Hi Guys!
I have a object with a camera projection map. I'm using this object to create a sand simulation. Everything is working fine for the sim but I need to transfer the texture on the grain particles. Is there a way to do that?


Thanks@!

If I understand correctly, you essentially have a picture and want to make the picture colorize your particles.
You can probably use an “Attribute from Map” SOP or a “Color Map” node (VOP context) with a VOP and or ray SOP setup to get the color to the particles.

It would be a bit easier to clarify if you could post a file.

Hi, I have attached a exemple of my problem with a simple scene.
I have a sphere that have a image camera projected on it.
I would like to transfer the color of this projection on the sand simulation that i have created with this sphere as the emitter.
I tried to use the Attribute from map but its not using the projection UV but a orthographic UV.

If you could help that would be awesome!
Thanks!

Haven't worked much with particles before, but I think I got it.
I am sure you can optimize this, but the basic idea is to inherit the point attribute Cd from the source geo.

Thank you DASD!
It works great! So you need to subdivide the original geo to get more points.
I will test this in my project scene today.

Thanks again!
