Hi, I have Carrara now a few days and discover its features. Now I have the first problem.
Animations with turned on GI causes flicker in animations. Is there a way to avoid this?
Here an example with Irradiance map for every frame turned on. (See the flicker on the lights)

I have made the whole Animation with Irradiance map for static scenes, but this cause another Problem. Look where the figure starts walking, there is a dark shadow artifact.

Is there a solution to use GI in Animations with turned on Irradiance map for every frame?  :blink:

Hi Mazak, Can you indicate on your jpg files where the flicker is occuring. I'm not seeing it on the jpg files or the move... :-/ Mark

Download the pictures and view with an picture-viewer program like Irfanview. Switch through the frames and you will see the flicker.

What I saw there looked like jpg artifacting not flicker. In the animation if you aren't satisfied check your compression settings this will cause artifacting. Output to avi first. Also check shadow settings.

No need to think outside the box....
    Just make it invisible.
