Instance Animation via RawTexture3D

Dear babylon.js friends,

I am trying to orchestrate per instance animations using a ShaderMaterial and RawTexture3D. The vertex animations and targeted vertices are not always as I would expect.

For example, in the following PG, I expect the larger instance to have its top vertex animated down and back up by 3 units, yet it doesn’t even animate. I expect the smaller instance to have its top vertex move up 1.5 units then back down, which it does. I do not expect any of the bottom vertices to animate with the given settings, yet they do.

Any insight into why my perceptions are incorrect would be greatly appreciated.

Looked into your project and noticed that you were normalizing the pickPoint against its own length rather the lengths of its components.



Thank you so much @ranjian0 !
