rendered issueSomehow my animation is not rendering, it just render every frame I tell it to but no change in actual object movement. The playback in viewport is running fine.

Also, I used random per island to assign random color to each sphere, but when I render on random frames their color kept changing randomly, how can I make the color stick to each sphere throughout the entire timeline?

Link to my .blend file

Edit: I solved the not rendering animation problem with Realize Instances node in geomatry node editor. But the colors are still changing every frame.

my shader node setup

  • $\begingroup$ pls provide blend file because we have no idea what you did except for this one shader node. I just can assume that you generate new islands somehow.... $\endgroup$

  • $\begingroup$ @Chris The screenshot says it's version 3.6.0 $\endgroup$ Commented Jul 14, 2023 at 10:39
  • $\begingroup$ using 3.6 right now, could you try rendering a few frames? The issue I'm facing is not in viewport but in rendered images (especially around the 45-65th frames, when the spheres begin to separate). Appreciate your help! $\endgroup$

hopefully you want a solution, and not(!) that the random per island works somehow...

so here is my solution proposal:

by using this GN setup:

you create your "own" randomized per island attribute and you can use that in your shader node tree:

result (this time cycles rendering ;). ):
