Primitives Color

[modjtaba]

Hi
I've made an effect using Houdini primitives and they have colors. I used attribute promote to send colors to vertexes and added Cd in to attributes tab of Octane Object Properties.
using new Color Vertex Attribute node in octane its displaying white only,

note: when I convert it to poly it gets white again in Houdini itself.
Thanks

Hi,

Can you share an example scene with this issue to take a look at it here? The vertex colors should work on the mesh objects without problems.

OK, got the Idea. problem was with my attribute promote,
I shall promote from Primitive to Point and Share Cd in octane attribute tab from Point instead of Vertexes,

Thanks Juanjo

Yes, the problem is that you are not working with polygons. Your primitives are packed geo that only support point attributes. If you still want to use vertex attributes, you need to unpack the packed primitives transferring the Cd attribute, as you can see in the attached image.
