What are the exact version numbers of After Effects that you are using (for both machines)?
laptop: CC Version 22.214.171.124 and CS 6 11.0.3 ( the client uses CS6 so I kept it for compatibility)
desktop: CS6 126.96.36.199
thanks for you suggestion.
That's true and I did upgrade the desktop: CS6 to 11.0.4 last night before another render just to eliminate this as a potential problem.
However, After Effects crashed again after rendering about 2 min worth.
So, I don't think the version of After Effects is the culprit here. Any other ideas?
Trying tiff sequence next.
Check composition settings>Advanced>Shadow map
Check, by holding down the shift key while opening preferences Preferences>Secret and set purge after every couple of frames.
Turn of MP rendering
If that doesn't work try a 4K render with different source footage, even a still. If it works with different footage or a simplified comp then go back to your original comp and start turning things off one at a time until your render succeeds.
thanks very much for your comments.
I am still working though your suggestions to find the problem while working on several projects. Please could you tell me what the settings should be for Composition settings/Shadow map?
My composition settings>Advanced>Shadow map are: Classic3d: shadow map resolution: comp size.
I tried the purge idea but that was unsuccessful, looking at removing keyframes/replace footage next.
