Hi!

I'm currently working on a multiple color explosion, and I need to transfer the color of these points coming from a colored sphere inside a popnet node with the trails they have generated in another DopNetwork.

Is this possible? Any idea or suggestions are absolutely welcome.

you will find the answers there!

good luck!

That's very interesting, thanks a lot

you can generate vdb grids from arbitrary particle attributes via vdbFromParticles' “point attributes” multiparm, hence you can add Cd there to make a color vdb grid.

alternatively, you could skip creating a color vdb grid and simply modify the diffuse color of the volume shader (ie read the point color at rendertime with a pcfilter).

Thank you for your time, i will need time to apply your resource because of mi Houdini level but seems to be a good idea.
