poured powder material
« on: June 28, 2019, 06:38:36 am »
Hi

I am trying to create falling powder similar to the attached images.

I create a cylindrical shape in CAD, I then used the flakes displacement to create a sort of powdered material. I thought that I could vary the width of the stream by using an opacity map but it all ended up looking pretty terrible. Any suggestions on how best to approach a material like this would be much appreciated.

I could see this being very difficult and inefficient to do with CAD, you might want to try particle systems in a polygonal modeling suite such as Blender3D (free and open-source) or Maya/3dsMax/Cinema4d and import those particles into Keyshot for rendering/

Hello.

I didn’t tested it yet, but I think this can work with a sweep (like the flow of the powder), displace this shape a bit and use a scattering media for the powder. With a very high dense and a small transparency distance, it should look like the ref pics. You can control powder color in the diffuse channel and use a very dark grey as Albedo to give it a solid look.

Hope that helps

Cheers
