Serious accidents with control of the expression spacing based on z-position of the layer

I have massive crashes when you use this script expression below. I have just a text layer where I control the depandend letter-spacing of the current z position. From z = 0 to-500 (directly in front of the camera), the values are transformed by easyOut() from 0-10. So far, that's all.

Now when I duplicate this line of text several times and start to change its position, then the accident happens. Text layers more I have the sooner the crash. This occurs when the edition therefore not made involved. In the preview is the applied standard rendering engine.

Unfortunately, there is no specific error message - it indicates just that AFX no longer works and is now closed.

My system features:

I have 8 GB of RAM and 10 GB disk cache. That should be enough for a text flying around.

I use the latest Version of CC of AFX 2015.1 13.6.1.6 running on Windows Ultrabook (Lenovo Yoga 1) 8.1. No CUDA detected so the preview is rendered by the CPU.

Anyone has an idea why this happens? Help is very appreciated.

max_spacing = 10;
z_position = transform.position[2];
var new_spacing = easeOut(z_position, -500, 0, max_spacing, 0);
text.animator("Animator 1").property.trackingAmount = new_spacing;

This is my test scene:

You create a hole of logic by referencing the layer itself probably. Should not happen, then I would call it a bug. Probably to do with flaky matrix code also used to smack and a few other things. Try to use a Null value and parent the text to it. This would work much better.

  • Serious problem with watch since the software update

    Hello

    I have a serious problem with my watch since to do the update of the software this morning.

    Watch dial keeps flashing between the Apple logo, dial and access code.

    Watch does not respond when you try to enter the access code or button does not not so can't turn off to try to restart.

    I tried to disable pairing my iPhone 6s but watch be message saying "can't match Apple Watch - Activation lock could not be disabled on your Apple Watch because of a server error.

    Nothing seemed abnormal during the update, I just let him do his thing.

    Any help would be welcome.

    With great thanks

    Hi Nicola

    Try restarting your watch force: press and hold the side button and the digital Crown for about 10 seconds, until you see the Apple logo, then release them and expect the watch again.

  • Weird problem with control of the ring and foot

    So I have some sort of weird issue with a control of the ring and a chart. I'm with LabWindows/CVI on a Windows 7 computer. The part of the program I'm looking at is basically to navigate through data - there are several "transition" (rehearsals experience), and you can choose the one that you want to watch in the list.

    Normally, you would select transitional in the list, it plots the data, then it is done, basically. However, all of a sudden (don't know how long it spent for), when I select anything except 'Average', he made all the tracing and such, then it changes control of the ring to 'Average' (it is not plot the average data or generate all the reminders that I can tell).

    Now the thing the more bizarre as you can see below, it seems that the switch happens just when I draw something on the chart:

     

    So, it's just weird. The code in this section is here:

       if(uidc.polyon) {
                polynomial_subtraction(curr_data, np, uidc.polyord, 0); // 0 Skip for now
            }
    
            // Scale the curr_data for gains, then pre-scale the FFT data
            // to have no change in the power spectrum (multiply by (2/np)
            for(j = 0; j < np; j++) {
                fft_data[j] = curr_data[j]*2/np;
                curr_data[j] = curr_data[j]*uidc.fgain[i] + uidc.foff[i];
            }
    
            uidc.fplotids[i] = PlotY(dc.fid, dc.fgraph, curr_data, np, VAL_DOUBLE, VAL_THIN_LINE, VAL_NO_POINT, VAL_SOLID, 1, uidc.fchans[i]?uidc.fcol[i]:VAL_TRANSPARENT);
    
            // Prepare the data.
            FFTEx(fft_data, np, npfft, NULL, FALSE, curr_fft);  // Do the fourier transform
    

    DC is a structure that I use to better organize some UI controls and uidc is for display RAM variables, then dc.fid is the Panel that is embedded in the tab "FID", dc.fgraph = FID_Graph and corresponds to the chart control. Control of the ring is actually in a child Panel, dc.cloc [0]. FID_Graph has a point, it can produce, but the reminder is empty (no not coded something there yet).

    I have also considered that perhaps something in another thread (I don't think there is, but whatever) I see is the cause, however, this behavior still happens on that line. I tried to break in different locations, on hold, then continues, as well by adding a loop containing Delay (0.01), a loop of 100 times. Always happens after the conspiracy.

    Does anyone have any idea why this might be happening?

    Hi Paul,.

    I don't have a solution, but I wanted to point out that, even if you see the ring to change its value only when you call the function of tracing, that doesn't say what this function call that really changes the value of the ring. In CVI, some drawing operations are batched, for performance reasons, and the Panel updates only visually at certain times. One of those moments when you draw a chart data. Yes, the ring changes visually at this time there, but it is probably just 'catch up' a change earlier.

    As you are looking through the code, when the value of the ring, you can use the term > command update UI to force the update panel, so that you don't have to wait for the tracing function and see if all goes well this change happening earlier.

  • How to make an image/object move with edge of the layer effect another?

    Hello


    I'm doing a video presentation of Whiteboard.


    What I should really do is bind the sequence .png of the arm/hand to the effect of sequential race that I applied to the layer below, as to pretend that the hand movement draws this layer (which is actually a scanned hand drawing) after masks I created with the Auto route tool.

    Obviously, I need to find a way to do it to avoid creating keyframes for each unique hand (REALISTIC) movement.

    I train after effects CC 12.2. I have a composition of 'HAND' with 7 different .png goes on loop, stop motion such as; a composition where the edge effect is applied to the design and overall composition where I would like to merge the previous two.

    Does anyone have any suggestions?


    Thanks in advance

    It may be possible to copy & paste the masks of illustrator and join some of them in a continuous path, however, but otherwise he must get used to the fact that there is no automated for any solution. Some things just need a tedious manual work and it's one of those things...

  • view the psd with feather and the layer mask

    There is one case where I can't display a modified to correct Photoshop image in LR.

    If the PSD file has a layer mask with a feather, LR displays a hard edge mask.

    There is no problem with a normal gradient or shadow a layer style.

    I'm on CC PS and LR CC, latest versions.

    Anyone have the same problem?

  • Need help with dodge/burn the layer

    I am wanting to dodge/burn a photo that I have edited with several layers.  If I do a double bottom layer, then the healing marks appear.  If I do an empty layer, nothing of the dodge and burn appears.  I don't want to have to flatten the image.  What I am doing wrong?  How can I get it works.

    Thanks in advance.

    If I understand correctly, you want to dodge/burn on the net result of all of the layers. If so, add a layer of white on top of the stack and do Alt + Shift + Ctrl + E.  This creates a snapshot at all underneath. Identical to flatten the image except that all the underlying layers are preserved. Then make your dodge/burn on this layer.

  • Is there a control of the expression for the opening of a string?

    Hello

    Just curious, is there a control of the expression that allows a user to enter a string that could be read by the expression?  I don't see on the submenu Sub "> Effects options for expressions", but thought I would see if anyone has any ideas how to proceed without having to reference an external text file.

    Thank you for your time and help!

    -Laz

    Yes, it's possible, of course, and to make things even less intrusive, I couldn't access comment a layer attribute rather than rename them the current layer.

    But in my situation I am desirous of an AE to select artist in a closed set of channels.  I don't want to enter their own data for fear that there is something wrong with the formatting, etc.  I'd rather have a drop down of sorts for the selection.  Thus, creating null items in the project Panel, naming them with unique names, then dragging in the model and by applying an expression control 'Control of the layer' layer in quesiton, AE artist can choose one of these layers, and then my script can read the value of the control layer name.

  • Cluster (buttons and the radio channel controls) - select the right file

    I have a list of text files and I need to select and open an of based on radio button selection.  How to sync the radio button with control of the chain so that I can get the name of the control of the chain and open the right file name?

    The attached vi does not work as I would like.

    Edit: Or is there a better way?

    Depends on the source of the list of files.  If you embed it in LabVIEW via a table or another method, then obviously a recompilation must be made.

    If the list of files will come from a specific directory, then simply read the list of the files from there when starting of the VI (see example).

    Or you could store the list in the text file and read the file at the start of the VI.  You can edit the text at any time without recompilation.

  • Control of the expression / Slider control works with the percentage?

    For example, I want to do something with keyframes, so opted to use "regulator toslide ," but is now defined by the "cursor", if I put the wiggleexpression (2.5) and place 2 on the regulator to behind the scenes, knowing that the value will be replaced by the value of "slider" so in the case of the control slide was "10". , would look like this: wiggle (10.5)

    But I want to know is if the control of the expression of origin by a percentage and not a replaced, for the value of the slider control.

    Thank you!

    If the amount of your max value is set, then by creating the cursor to drive the percentage of this number requires a few simple calculations.

    Degree of accuracy desired percentage to be hover would require a small change that in mathematics.

    This example allows you to animate a percentage of '2' frequency (maximum value) in agitation, but allows the range '5 ': stay

    mV = 2; maximum value

    PERC = (effect ("Slider Control")("Slider")/100);  makes a percentage since the slider value by using 0-100

    Wiggle(MV*PERC,5)

    explanation:

    There are several ways to do so.

    The slider is unlimited, so you can define OTHER rules in your expression, but to keep it simple:

    You must multiply your maximum value of your "perc."

    However, we want to transform the number 'perc' in a fraction.

    A simple way is to divide the amount of cursor by 100.

    Multiply your max value with the result of your cursor (/ 100) and you have your percentage.

    (* You can use fractional numbers to animate instead of this, but the cursor is easier to control in this way.)

    Hello

    Uninstall Faultwire and look for the codes manually as needed. The link to troubleshooting blue screen
    page will show you how to get them.

    How old is the system? A real computer store (not the leeks and glances at a Best Buy or other large surfaces)
    Stores) can help to give a proper diagnosis of the machine.

    You can use Safe Mode - repeatedly tap F8 as you start - use to back up your data in a redundant
    way off the machine. Then re-install Windows that "might" help if the problem is software partner.
    Of course, you will need to reinstall your programs and restore the data in the machine.

    Although there are a large number of errors there could be a cause for all. Try to remove ALL power and
    reinstall all the memory cards and cables (at both ends, when possible) - actually delete and replace.
    do not just tight. Clean the dust bunnies (of course those who are for a PC - for a laptop to ensure that)
    the vents are clear). Try using a small fan blowing through the vents to see if heat is a problem.

    Update key drivers - display/video, NETWORK card and WiFi (network), sound (do not forget to check the sound card drivers
    What update because they will often rollback then repeat the installation until the correct version appears), modem
    and all of the other major features, you could have as 3rd party mouse or keyboard.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system. For
    each driver in the list, additional useful information is displayed: load address of the driver, description,.
    version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - Device Manager - Display Adapter - note the brand and complete model of your
    video card - double - tab of the driver - write version information. Now click on UPdate Driver (this
    cannot do anything as MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
    This will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party with their
    own the software and drivers and all other main drivers that you have.

    Now go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restoration) and then of the manufacturer of the device
    (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for the BIOS, Chipset and software)
    updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after each installation.

    Always check in the Device Manager - tab drivers version you install actually shows up. This
    because some restore drivers before the most recent is installed (particularly that audio drivers) so install a
    pilot - reboot - check that it is installed and repeat if necessary.

    Repeat to the manufacturers - BTW on device at the DO NOT RUN THEIR SCANNER - manually check by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    If you update the drivers manually, then it's a good idea to disable the facilities of driver in the Windows updates,
    This leaves ONE of Windows updates, but it will not install the drivers who are generally older and cause

    NOTE: Often restore audio drivers to check the version after installing and restarting is
