Continuously changing ID of object with utility node

[Hadrien_palanca]

Hi everyone,

Does anyone know how to fix object id with instancied object and keep the same ID for the whole animation ?
I have found that it happen on frame to frame that object ID (with utility node shader) may change and messed up the animation. I have a scene with a lot of character, same mesh, different texture according to the object ID (with utility node). So I would like to make sure that each object ID stay the same on each frame. Actually object ID can change on one frame to another this lead to a change of texture on every frame for my characters and motion blur thinking that they are different object on each frame, here is a quick video to illustrate that.

Can anyone help me on that ?

Thanks

The problem with the Cloners is that they always regenerate their object cache and in some cases it's impossible to track the objects between frames. For instance if the number of objects changes. I'm not sure what's causing the flickering in your scene. Do you really need that History Depth in the MoInstance nodes?

Ok, I understand, indeed I don't need that history depth (default setting), maybe I will try to replace those instances with cloner but I am afraid that I may be facing the same problem with cloners even if the number of object doesn't change.
