Hi, I'm animating instances on a surface by controlling the size by a null. I have a random texture on the instances but when I render the frames out the instances change color every frame, attached is my set up what am I doing wrong ?

How are you rendering the scene, in update or full scene reload mode? This sounds like a scene full reload that is changing the instances IDs, or something like that.

If you want to share a scene with this problem, I could take a look at it here.

Thanks,

I've been checking your scene and I'm afraid that there isn't an easy solution to use the random texture with your instances. The problem is that the number of instances is not the same in all the frames, so after reloading the instancer for each frame, the IDs used to get the random texture change. Perhaps you could use a texture in world space to add the random appearance or something like that, but not the random texture node.

Thanks,

Just make a few variations of the source object with a different color.

Thanks for looking into it for me and explaining the issue I just added separate models in the instancer in the end. Thanks
