color and attribut from points to VDB

Recommended Posts

Hi,

I'm trying to pass the color from polygon to VDB, transform the VDB then apply the color back to polygon but I don't know how to do.

 I tryed to use "VDB advect points" but I can't figure out how it's working and if it's the right solution.

Hello,

You could use a VDB from polygons, add Cd as a surface attributes, then in an Attribute VOP use Volume Sample with P as position.

Hi Tanto,

Thanks for your answer.

So I did what you said and it's working on the first frame.

Now, the problem comes from the advection I guess.

The colors seams to folow the turbulence but not perfectly.

 

Anyone has an idea ?
