At least I can get my playback in AE to be correct by Purging the Cache, but I need to be able to render out a final movie.
And upon futher work I was able to get an output with "Render using Open GL" checked, but I was told not to use this by Todd here: http://forums.adobe.com/thread/734343
Is this still true, or did this change with the update?
If rendering using OpenGL gives you results that you're happy with, go ahead and do it. But most people aren't happy with it.
I'm guessing that the reason that rendering with OpenGL made things work is that OpenGL turns off Render Multiple Frames Simultaneously multiprocessing. Try turning that off directly and not using OpenGL.
First my specs, just in case:
MAC OSX 10.6.6
AE CS5 10.0.1.19
24 GB RAM
That kind of machine ought to work well for multiprocessing. So if Todd recommends turning multiprocessing off, you simply may have your memory and processor allocations out of whack.
Check out this blog, also by the Good Mr. Kopriva:
It's possible that there's a bug with how the Illustrator files are being used when Render Multiple Frames Simultaneously multiprocessing is turned on. I haven't seen such a thing, but it's possible.
If I turn off "Render Multiple Frames Simultaneously" OR if I use Open GL, then the project Renders just fine. However, with "Render Multiple Frames Simultaneously" off the render time is increased to about 13 min for a 30 second comp.
Could it have anything to do with Nesting my composition? If I have multiple 3D .ai layers in one comp, and I precompose/nest that comp inside another one, should I turn on 3D for that nested composition, or should I leave it off? And if I leave it off, will I still be able to navigate a camera around those objects in 3D space?
I'll try turning off 3D for the nested comp and then see if Render Multiple Frames works...
Also, thanks for the quick replies, and I'm sorry it took me a bit to get back on this one. Busy Busy all the time!
No dice with that last one... seems I'm stuck having to use OPEN GL or have "Render Multiple Frames Simlutaneously" Turned off for the moment. Not a huge issue I guess, as I can still render a higher quality one without Open GL, it just takes a while...but its kind of a bummer that I can't utilize some of the extra power that my system has.
BTW my RMFS settings were
RAM available: 24GB
Ram Reserved for other Apps: 8GB
RAM for AE: 16 GB
Installed CPUs: 16
CPU's Reserved for Other Apps: 1
RAM allocation per BG CPU: 3 GB
Actual CPU's that will be used: 4
I'll keep messing with my settings and renders when I have time, and I'll let you guys know if anything changes. Again, I appreciate the help.
Unfortunately I have no solutions but I am having the exact same problem. It seems to be some type of bug as all can be fine and well one minute, then you save & exit, go back in later and an illustrator layer has disappeared. Again, the layers are not disappearing in the timeline, just in the active camera view. I've noticed when they disappear in RAM preview, they are still there when scrubbing and vice versa. My setup is pretty feeble compared to yours so perhaps it is just a RAM thing...
MAC OS X 10.6.5
2.4GHz Intel Core i5
AE CS5 10.0.1.09
AI CS5 15.0.0
I should also point out that I already had 'Render Multiple Files Simultaneously' switched off when the problem started. I've just discovered that if I bring the resolution down to half on the RAM preview then everything is back so perhaps for me it is just the frailties of my machine...I don't see how that could be true in your case though...
The half res solution was short lived I'm afraid, I have 3 layers which are taking it in turns to disappear. You can make them visible by putting the preview down to half res, then they disappear again, upping it back to full res or putting it down to 1/3 then seem to solve the problem...for about 5 minutes. It's now got to the stage where I'm constantly changing the display resolution just to see my layers again. The real bad news is that despite getting the preview to the stage where I can see all of my disappearing layers & everything is behaving as it should, the render is missing a layer.
Is nobody else having these problems? This is an absolute nightmare.
This sounds like exactly the same issue I was having. If I messed around with my resolution settings, some layers would appear at certain points, and some layers would disappear (in active camera). However, I noticed that if the problem all I would have to do was "Purge" the cache (Edit>Purge>All, and everything would pop-back. Hopefully this helps you a little bit. I have yet to fix or figure out a solution to the problem for a Final Render with Multiple Frames Turned on. Perhaps this is a bug then? At what point do we consider submitting a bug report/request?
I can verify that this is happening to me too routinely since moving to AE CS5. It only seems to happen to Illustrator layers. It is possible to get the layers to display properly if they're exported to Photoshop but this is not a solution for most of my purposes.
This seemed to be an issue with the continuous rasterization bug that is documented elsewhere on these forums. If you make sure that every layer with the illustrator files has "continuous rasterization" turned on, then it should fix the bug, or at least it did for me.
None of these standard solutions have worked for me; or in some cases, they seem to work, then the problem recurs. Among the standard fixes that I've applied are: switch on Continuous Rasterize for all Illustrator layers, turn off Render Multiple Frames Simultaneously multiprocessing, and turn on thumbnails in the Project panel. Last time my Illustrator files weren't appearing, I was able to get them to show up by converting brush strokes to outlines in Illustrator and resaving the files.
The Illustrator files are now working okay as long as they're 2D, but I've just converted them to 3D layers and I'm back to square one. I can see the layers in Active Camera view but they disappear in any other view; and when I can see the Illustrator layers, they don't respond when I move the camera around and act as if they're 2D.
After Effects CS5 is now unusable for me. I'm going to have to revert to CS4.
I'm also having a problem with disappearing Illustrator layers in AE CS5.
When I open up the comp, only the layer bounding boxes and anchor points are visible against the background color. The layers have become entirely transparent, but opacity is set to 100%. The asset thumbnails in the project panel are also affected.
Here's the really strange thing: the layer visibility will return temporarily if I open the layer panel, and click the layer eyeball on and off. When the file is opened again, the layers are invisible again.
Rebuilding the project, reloading the assets and purging the cache makes no difference. Turning on the continuously rasterize switch for each layer does seem to help. This is a very, very simple 2-D test comp: no nesting, effects or even animation yet. I will probably try rebuilding the project in AE CS4 to see if the same problem occurs.
I'm a beginner and have only been using After Effects since last fall (iMac i5/16 GB running OSX 10.6.6).
I soooo had this problem late last night at 1 am in the morning, and though my project is due today, I got so frustrated that I just shut everything down and turned my computer off! But, when I opened up everything this morning, it was working fine... (twilight zone soundtrack music)
After reading everyone's posts, the only explanation I have is to shut it all down and restart your computer. My computer is set to clear all my caches and other extras, which refreshes the computer's RAM and resets the program software. If you're work load is as big as mine (or bigger) you might set your system up to do the same, clear everything out, SAVE AS, and Restart. As long as you can see all your layers and effects, and the problem is being able to see a preview in active camera, this should work.
I am experiencing this problem as well, and while on hold with Tech Support (who told me no solutiuon exists) I figured out a solution that so far has worked for me. The problem is in how Illustrator saves the file; by default "use compression" is checked; after re-saving the AI file with compression un-checked the problem has gone away.
Great that you solved this for your project. I always uncheck compression, so this solution won't work for me.
I finally gave up on my comp with disappearing layers & moved on to other stuff. Fortunately, no problems with infinitely more complex projects in CS5.5.
We've been having what sounds like the exact same problem at work, and nothing seemed to help. We tried turning off the multi-processing, turning on/off open GL, continuously rasterizing the illustrator layers, nothing worked... Until we realized that our Illustrator files had a second, huge artboard surrounding Artboard 01. Deleting the larger artboard fixed the problem.
Thanks for the response. What worked for me was re-saving the AI file without compression. Nice that you could solve it one way, and I could solve it another, but Adobe tech support couldn't at all.
We tried that too! And weirdly, it seemed to work after we did that, until we closed the project and came back to it.
I had the same problem. I did a render in HDV (1280x720) MP4 and some layers they disappeared when I tried to do render.
The solution that I founded is make the render without compression. Only AVI Uncompresed UYVY and after that compress the clip to the format do you need with the Media Composer.
It was the solution for me.
Suerte y saludos!.
Thanks for the response. What worked for me was to re-save the Illustrator file with compression turned off.

i'm using CS5.5 and i had the same problem... Some layers dissapeared, others were half visible (seemed to be cut). Changing AE setting didn't help, only saving the AI file without compression worked out, at least for now. Pity that AE developers haven't fixed that bug in CS5.5, since it already appeared in CS5
There was a known issue with layers disappearing when Render Multiple Frames was turned on that was fixed in AE CS5.5, but this could be a different issue. Can you send in the project with the illustrator file in a bug report here? Mark it attention Will Lockwood and I will take a look.
richardbwallace solved this for me thanks A LOT man! Tried resaving with compression off, didn't work. Deleted the large artboard and now everything is rendering perfectly with multiprocessing on.
>Go into your illustrator file
>Zoom all the way out until you see the grey area around your artboard.
>Select your artboard tool on your left toolbar
>Select the large surrounding artboard, press delete.
You don't have to zoom out but it may help in selecting.
I am on CS5.
Been battling with this for months and was forced to work with multiprocessing off! Thanks again Richard!
I have found the genesis of our problems. I first noticed this on a project where I was using Illustrator (CS5) artwork supplied by a designer. He was using the "Film/Video" presets to make an HD formatted AI file. I liked how handy the grids and title safeties were so I kept using the preset on other projects. Thats when I started noticing artwork disappearing. I had to purge it at multiple points in my timeline just to get a render out.
When I read richardbwallace's idea to look for the second artboard and delete it, everything clicked into place. Instantly everything came back. I have a feeling that Adobe needed to add that artboard to make something in the film and video presets to work the way they do and didn't anticipate or test for this issue.
I have not checked if other presets use the same double artboard trick, but if one of them does, I bet it will cause the same problems.
tl;dr - Video and Film presets in AI add extra artboards which cause the issue.
CS6 Illustrator layers interface (labels and icons) - appear / disappear
1. Open layer panel
2. Double click layer icon above the affected layer(s) object(s) that do not show in the layers panel
3. Enable print
Layer interface data re-appears. This influence cascades to any layers & objects below toggled layer print/noprint
Further testing for the tech boys
- Creat New Document
- Create Box inside artboard
- Create layer 2 - make box inside artboard.
- Dble click 2 disble print. only that layer is affected
- Enable print on layer 2
- Create a rectangle on layer 2 that spans the artboard and beyond the art board
- Disable print on layer 2 - all layers below go blank
- Enable print on layer 2 - layers below reappear
- Delete the spanning box
- Disable print layer 2 - layers all disappear. its like it remembers the object outside the artboard and continues with the bug
anyway I have other things to do today ... so fix it Adobe
I'm having the same problem. Running Illustrator CC on a MacPro 2 x 3GHz Dual core Xeon, 8GB RAM system 10.7.5. At the same time the Mac also slows down. Some files are fine one day, then the contents of the layers palette disappears the next.
I have now reverted to CS6 and the problem has gone away.
I can only assume that it's a preferences problem. I would appreciate advice on which files to trash. Does a clean install work with CC?
I now have a fix for this plus the problem of the inability to log into the cloud. The two seem to be related. The fix is here; http://helpx.adobe.com/creative-cloud/kb/unknown-server-error-launching-cc.html
Going through their trouble shooting plus deleting the Illustrator 17 preference files in the application support AND the preferences folder is necessary to perform a complete fix.
What worked for me was to turn off Motion Blur for those layers.
This seems to be an old issue that has just occurred for me in AE CC 2015 so does that mean that the bug has not been fixed?
Re-saving the illustrator file and un-ticking "use compression" also worked for me. I wasting a lot of time figuring this out so would be good if suddenly layers in AE didn't just disappear.
