Element 3d "flicker" when rendered?
on Mar 6, 2016 at 10:57:04 am

Hello,

I have recently been playing around with element 3d, and I produced a shot with the jet that I am pretty happy with, however there is 1 frame of the final video where the jet disappears - it doesn't do this inside of after effects, however the video rendered from media encoder has this blank frame.

I tried rendering a version with only the jet and necessary lights (no particles or background) and had the same problem, suggesting to me it is something to do with element 3d.

Does anyone know what may be causing this?
Thanks.

The first thing I would do is purge all memory and disc cache and see if it handles the problem.

I remember having an issue like this and needing to 'force' Element to redraw each frame.

Easiest way to do this is add a really small wiggle expression to either your camera or jet so that each frame is unique.

For example:

wiggle(0.01,0.01)


Try increasing the numbers slightly if nothing happens. But don increase them so much that you actually see the object or camera wiggling around (unless you want that effect).

Hope this helps.

Lance

Hi, how did you fix the problem? Add a wiggle expression?

Yes. That solved the problem for me.

Essentially you just need to trick E3D into seeing every frame as unique so that it doesn't try to cut corners when rendering.

Back in the day it was well known that element had to have a moving camera, even if ever so slightly. So thats why wiggle works
