• Number of layer effects + table with the names of the effects

  Hello

  1. I want to ask you, if you don't know the function to count the number of layer effects.

  2. I need function which returns the array with the names or identifiers of the fot effects each layer.

  I what T/F back function if layer has effect. But I don't know how

  write this.

  Thanks Domaneni

  This function will return an array of names of effects for the active layer. You can get the number of effects of the length property of the table. Effects names are names of equity manager so if you want that they correspond to the GUI, you will have to translate. that is the line in the action Manager is frameFX

  function getEffects() {
      var ref = new ActionReference();
      ref.putEnumerated( charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );
      var desc =   executeActionGet(ref);
      if ( desc.hasKey( stringIDToTypeID( 'layerEffects' ) ) ) {
          var effects = [];
          var effectDesc = desc.getObjectValue(  stringIDToTypeID( 'layerEffects' ) );
          // first key is scale so skip and start with 1
          for ( var effect = 1; effect < effectDesc.count; effect++ ) {
              effects.push( typeIDToStringID( effectDesc.getKey( effect ) ) );
          }
          return effects;
      }
  }
  

• get the number of layer of selectedLayers array

  I have "app.project.activeItem.selectedLayers", which returns an arbitrary collection of layers of the model. It can be layer 2, 5, 6 etc in the chronology of the model. However in my collection of selectedLayers they are referenced by index IE. 0,1,2 or 3. Is there a method to get the number of layers in the comp? for example, if selectedLayers [0] refers to the layer 2 How can I access the layer number.

  I think that's what you hear:

  app.project.activeItem.selectedLayers [0] .index

• How to get the layer number/id?

  I tried searching the forums, but found only inDesign (code 8)

  So the question is: How can I get layer number (defined by its name, or current layer)?

  Thanks in advance.

  If there is no game layer, you can use something like this.

  That will tell you how many layers with the name 1, and then select the last one.

  layerOne var = [];
  var doc = activeDocument;

  for (var a = 0;<>
  If (doc.layers [a] .name == '1') layerOne.push (a);
  }
  Alert ("the number of layer on =" + layerOne.length + "layer numbers =" + layerOne.toString ());
  activeDocument.activeLayer = doc.layers [parseInt(layerOne[layerOne.length-1])]; Select the last layer 1

• After effects layer properties Auto expands when I click Hide, Unhide, Lock, Unlock

  The title pretty much says all of this, I tried to search if this has been discussed before but no could not find anything.

  I'm on the latest version after effects CC, 13.8.1.38.

  This ONLY happens when the composition I work has enough layers to display the vertical scroll bar (which means that the number of layers exceed the size of the size of screen/composition). If I click Hide/Show or lock/unlock on any layer, it automatically increases its content makes life very irritating because I have to close it manually each time. If I increase the size of the composition window Panel so that all layers are visible (i.e. no vertical scroll bar) so it no longer occurs. So the key to triggering it is to ensure there are more layers than your screen has space to show in this Panel.

  I've looked everywhere in the settings and couldn't find something to turn it off. I know that the fastest solution is to keep the composition and store the number of layer, but it is not always possible for me that I must continue to work with items broken down in the same composition. My workflow would be more complicated if I continued to switch between the tabs before publication.

  All solutions would be highly appreciated I just can't work with this 'feature' useless. Thanks in advance!

  This is certainly NOT a feature is not that it is useless, it allows to work with layers of worse.

  Let's see if we are talking about the same thing. Here is a composition with multiple layers:

  

  I press the lock or hide and everything seems the same:

  

  so if we are talking about the same thing, there is something wrong with your software.

  try to reset the preferences Ctrl + Alt + press on the launch of the app you except that you please provide screenshots of before and after, and perhaps a video capture if you can and we will consider here.

• Is it possible to recover a layer that has been deleted?

  I'm trying to manage a layer last night and I was really tired, and anyway I ended up accidentally delete. Is there a way you can retrieve a layer which is eliminated?

  Unfortunately, the cancellation does not work on the command to restore a layer removed (at least not in 3.1.2

  I think that is why the secondary button appears when you press the trash can - reminder a little "are you sure".

  If you get to the layer 10 maximum, you could start a practice to duplicate the project before you delete layers.

  If you do not reach the maximum number of layer, just turn off the layers you don't want, then make the layer delete decision in Illustrator CC later.

• Active layer reference as the index when loading external text file

  I have a series of text animations, and I want to be able to load the content of the text for the layer of an eternal file.

  It is referenced in many places (I saw him here external text of Pro video Coalition - Expression Shorts - read the Document by David Torno), and the script is usually as follows:

  try {}

  myPath = "~ / Desktop/source.txt ';

  $.evalFile (myPath);

  eval (thisComp.Name) [0];

  } catch (err) {}

  "MISSING."

  }

  In this case, the layer is always array index-, so I would be able to replace the specific reference to the array index by a reference to the current number of layer. This allows a simple duplication of the expression rather than having to change each term individually for each layer. I think that the property that I need index - but it does not work! Or not the way I use it anyway.

  It is (a) of the terms I've tried

  eval (thisComp.Name) [thisComp.index];

  On layer 9 the error indicates the property! or method named 9 in the Array class is missing etc - so index 9 is interpreted correctly, but I use it wrong.

  Resolved, with the help of this post Re: disorder of the eval expression

  Solution - without the try catch block is as follows (including some debugging... stuff):

  myPath = "~ / Desktop/source.txt ';

  $.evalFile (myPath);

  myLayer = index;

  "result:" + myLayer;

  typeof (myLayer);

  myArray = eval (thisComp.name);

  myArray [myLayer];

• Maximum number of layers?

  Hey everybody,

  After obtaining a degree, I can no longer add folders in folders. Example before, I made a folder with 20 layers and another folder with 15 other layers. Right now, I can't put these two files in another folder.

  I tried dragging files on the buttons folder on the Layer palette. Using "present" and "send back" to force the files in the new folder. Restart Photoshop. Checked the menu Preferences in Photoshop for what anyone talk about records.

  
  Any help would be great. Thank you.

  Layer games?  There is a limit to how deep they can go: only 5 deep.

  But there is no limit on the number of games, or the number of layers that can be included in a set - less than the limit of total number of layer (which I think still is 8000).

• Satellite M55-S325 DVD write error (MAT * a DVD - RAM UJ-years 840)

  Hi all
  I have a Satellite M55-S325 with MAT * A DVD - RAM UJ-years 840 Firmware Version 1.52 I bought States 5 months ago, everything seemed fine until a few weeks ago when I tried to write some data DVD, I had unrecoverable errors while writing the DVD using NERO 7 ULTRA EDITION, but now I get this messege all the time and I'm not able to write any DVD the disc seems to be well in CD writing. I tried to use recording SOUND now that comes with the laptop, no luck. I tried to reduce the size of the files, and try with lower write speeds but still no luck. I disabled burning CD of the Windows XP SP2 IMAPI burning service COM as well. I use a good quality DVD-R that worked fine before. I would appreciate your help because my HDD is almost full (but still 10 GB of free space) and I need to get a backup of my data.

  Hello

  I can't find any strange or mysterious messages in the log file.
  You suggested that the drive can burn CDs but not DVDs.
  The calibration lens dysfunction is sometimes responsible for these issues.
  Unfortunately, I have no solution for this problem. The replacement drive must resolve.
  The unit is fairly new in this case, you should ask for help ASP.

• Problem of zoom of the Earth.

  I'm on Adobe After effects CC 2015 version 13.5.0.347 software. I have problems when you follow the tutorial of zoom of the Earth by Andrew Kramer at video copilot. I have the same problem as the guy in this thread: focus on Earth

  The first layers I have is pictures of inside a fireplace. I want the zoom to start at the bottom of the fireplace and all goes well until I reached the point where I have to unparent all the layers and assign each layer but the number 1 for the number of layer 1.

  [QUOTE]

  After checking that all the layers have no. PARENT, it assigns then all layers (except the first) to have the first layer as a parent. Then, it adds a key and scales image.

  As soon as I add the keyframe of the scale, all the layers below no longer appear, and when I move the slider along the timeline, it just zoomed in and out of layer 1.

  [/ QUOTE]

  Layer 1 is really huge and everything I see while moving the cursor is the number of layer 1 and Earth in the background. If I do not use the images of the fireplace and the only screenshots of google earth, it works perfectly. Why?

  Note: I've done this before and it worked very well, but it was on an older version.

  It was interesting! Thank you for the challenge. In fact, I learned something new today

  the problem is that you are parenting in a layer of 0% scale - you can do that, because when you use parental responsibilities, Ae does some internal calculations for the parental relationship to work S01.jpg... in this case it is the scale of values, and divide or multiply by 0 will be 0. all layers are turning when you their parent to a layer of scale of 0% to 0% right scale.

  you have another problem - for reasons X and Y scale of the first layer (the one you are supposed to parent) is not the same:

  

  Do you more problems when you parent he other layers.

  What you can do is this:

  1. create a null value

  2. copy the position of the first layer (S01. JPG) null - null value is now in the exact same place as the first layer

  3. change the scale of the null value to 0.1%

  4. parent of all layers of the null

  5. the null value for your animation to scale and will continue as planned.

  more information on how you got in this mess:

  I am looking at your configuration, and is not like Andrew. Here's Andrew Setup:

  

  the top layer of most is 100% and all others are growing nationally.

  It's yours:

  

  the upper part is more than 0% and others are growing nationally.

  so the problem is that you are parenting in a layer of 0%. Parenting generally did a good job hiding it does under the hood, but when it comes to scale, you could find situations where he just lost in the mathematical calculations to make it work: 0% is a case when it does not actually, non-uniform scale would be the other when she will distort your child. When you're parents, under the hood after effects done some math. Well, not quite under the hood - you can actually see, even if your layers will appear as usual.

  Take these two layers: at the 100% level

  

  Now parent layer 2 layer 1 - What do you get?

  

  scale values alike. Now let's cancel the parent and change the scale of 1 to 10% of layer

  

  even now as before Let's parent layer 2 layer 1

  

  wait what? 1000%?  It's just the internal wiring of the layers for the parent feature. AE did some calculations here. But what happens when you divide or multiply by 0... ? you get 0. That's why your layers disappeared. DETECTIVE CONAN!

• Slow with many layers of Photoshop

  Hello!
  
  

  I do experience notable in Photoshop slowdowns when working with large files (more than 4000 x 4000 pixels) with many layers.
  I tried different things, like tinkering with performance options in Photoshop, brush settings and global PC settings.
  Nothing seems to help.
  
  When you start with a new file (say 4000 x 4000 pixels), everything seems fine. As I work, I create layers more. When the number of layer approaches 80 ~ 100 I start noticing significant slowdowns. The Brush tool becomes lag (delay adds boring), zooming and paning is smoother and everything becomes overall slower.
  
  When checking in the Manager of tasks, either the graphics card or RAM or processor is fully utilized. Total CPU usage is usually only 20 ~ 25%, 50% of RAM but Photoshop is lagging as hell.

  I think I have a quite decent PC. (at least for this type of workload..)
  My PC current specifications are:
  
  CPU: i7 6700 k @ 4, 0GHz
  RAM: DDR4, 16GB, 3000 Mhz
  GPU: GTX 980 Ti
  2xSSD RAID-0 for the main system partition (Photoshop "scratch disks" can also be programmed to do this).
  Windows 10

  
  So, what could be the problem? Any ideas I could try?
  Or should I rethink my working habits of several layers?

  Update!
  After more inexperienced, seems to have finally found the culprit that is causing slowdowns.
  Layer blending Options. Especially those that generate their own semi-transparent area.

  I can reproduce this in the layer file 10:
  (1) create a new file with the dimensions of the 6000 x 6000 pixels (or something bigger) with no background
  (2) draw something
  (3) add option 'outer glow' merger with significant RADIUS
  (4) add a few more layers, repeat steps 2 and 3
  (5) create new layer below all other layers and try to get something in the area where overlap the effects of "outer glow".

  So the main takeaway:
  Be careful adding mixture of options to layers and rasterization them where possible.

• Canvas custom script

  The following sequence can be scripted in PSCC 2015.1.2?

  1 - get the number of layers in the active document

  2-call canvas size dialog box

  3 - Get the height of dialog canvas size value

  4 - Select vertical to the bottom of the anchor

  5 multiply the height by the number of layer

  6. create custum canvas

  I don't know if will grow them in the right order:

  #target photoshop
  var oldPref = app.preferences.rulerUnits
  app.preferences.rulerUnits = Units.PERCENT;
  
  var doc = activeDocument;
  var numLayers = doc.layers.length;
  var newSize = numLayers * 100
  canvasSize ();
  
  app.preferences.rulerUnits = Units.PIXELS;

• Very slowly pushing in CS6

  Hello-

  I've seen quite a few threads but no solutions but who work for this problem. My documents tend to have a number of layers, using very frequently shapes with layer effects. up to a certain amount of those, the app is very sensitive, and then once I've reached a certain level it becomes very slow. strange that moving a vector shape with the direct Selection tool is very well. regular repositioning of a group or a layer brings up the progress indicator dialog box.

  so far I have tried:

  -Disable layer previews (improve things a little bit, but still unusable with the largest number of layer)

  -changed the performance parameters (cache level: 2 or 4 and tile size 128 k) (also no effect)

  the only thing that seems to help is to divide the file in seveal apart those who have fewer layers, but this isn't really a viable long term for me, I use layers in and need a more global vision.

  others found a solution? I can't imagine being the only one with this problem.

  Thanks in advance for your throughts.

  Yes, related to the layer thumbnail. If you turn off layer thumbnails, or change them to "entire document" instead of 'boundaries of the layer', the problem goes away.  Default CS5 to "entire document" for layer thumbnails, so did not show the problem.

  And the good news is that it relates to a difficulty that I already have in the tests.

• generate the ramp of the order of the layers

  Is there a method (effect or script) that will apply a linear ramp to layers based on where they sit in the comp?  For example... If it is a composition of 100 layers, layer 1 would turn white and 100 layer would be black.  Any help or advice would be greatly appreciated... trying to figure out a quick solution to generate a picture of ramp based on the order of the layers.

  Thank you!

  Siri and my iPhone help me with this answer.

  You can apply the hue and saturation of your layer. You can then add an expression to the brightness value.  The expression is very simple.  It only requires that you know how many layers to use.

  If you have 100 layers and a composition of eight bits and then each layer must be reduced in luminance of 255÷100. Expressions include the number of layer by using the index of the expression.

  The expression looks like this:

  (index - 1) * 25.5;

  Now just duplicate your layer 100 times.

  The top will have a luminance you 04 Black, the background will have a luminance value of 255.

  I'll doublecheck this when I get to a computer, but I think it's perfect.

• Effect that takes place

  I came across an animation illustrating a series of diagonal lines takes place as a fan. The work is pretty simple, but I didn't know how to build this legacy and I was wondering if there could be an expression to create this kind of effect.  I appreciate any suggestions.  Here is the link below for the animation.

  It's just an exercise in basic mathematics. If you place a control slider on a layer zero, and then use the index (the number of layer) as a multiplier you can fan the layers by simply adjusting the slider. Add to this an if else statement to count the number of layers and stop to increase the angle when the circle is filled and you have the solution.

  If you put the layer zero with the slider at the bottom of the layer stack this expression should work for you:

  ctrl = thisComp.layer("Null 1").effect("Slider Control")("Slider");
  numSeg = thisComp.layer("Null 1").index - 1;
  val = 360 / numSeg
  
  if (ctrl < numSeg) {
       mult = (ctrl * (index -1))*(val)/numSeg
  }
  else if (ctrl >= numSeg) {
       mult = (index * val)
  }
  value + mult
  

  CTRL is the value of the slider control

  numSeg counts the number of layers of line in the model by subtracting 1 by the number of layer from the layer of null (null must be down)

  Val calculates the angle between the layers when they are uniformly distributed in a circle

  If the statement indicates whether the CTRL (value of the slider) is below the number of segments can multiply the value of cursor multiplied by the number of layer 1 (so the top layer does not turn) and then divide this value by the number of segments.

  The other if the statement indicates if the value of the slider is equal or greater than the number of layers, rotate the layer by layer number multiplied by 360 divided by the number of layers. This evenly distributes the layers around the circle.

  The value + mult to the end just says take the initial rotation value and to add the new value of the rotation of this layer. This works if you set the rotation angle of the departure first layer. If you want to control after duplicate layers then replace the 'value' with the expression angle controller.

  All you have to do to make this work is to set the anchor point to one end of a line segment, add a cursor of expression to a null value, put nothing down, then add the expression to the line layer and duplicate as many times as you want.
