Hi everyone
is it in some way possible to assign different material to a volume meshed geometry animated?
I explain
Imagine you want to see an animation of a sphere cutting off a cube in a volume builder. I would like to see that inside the cube there is gold and outside of the cube another material but seeing the animation of the sphere. hope i’ve been clear.
If you don’t need to see animation but just need the geometry is easy, as you convert to geometry your volume and with phong break selection you isolate only the inside part. Is it possible to achieve this but seeing the animation?
thanx

Hi Luigi,

Please have a look here:

I used a 3D Spherical Gradient. The Start and Radius of this Gradient are taken from the Sphere. The Radius is doubled to allow the Sphere’s surface to have the color at 50% on the gradient. (Cycle is off!)

This 50% allows to have the cube in one or more colors) and the Sphere in another color.

Yes, that is limited to spheres or perhaps a cylinder. Other setups are quite more difficult or impossible.

Another approach can be done with a copy of a model and create a Normal Move with the model. Then build the different colors as a model.
The Volume Mesher Voxel Range Threshold might help here, or even the Volume Dilate Erode on the elements to get the sizes changed. It depends to a certain degree what you like to have.

Let me know if there is anything else; I’m happy to look into it.

Cheers
