Greetings,
I know the Geometry COP says “This COP renders geometry from a SOP as a single color image.”

However, I would like to also have the point color attribute (Cd) on the image.

In other words, is there a way to import an attribute from a Sop and have it displayed inside a Cop ?

Thanks,
Eric Gervais-Despres

Just stumbled across the same problem ..
Any solution found ?

You can use Intersect inside VOP COP generator to cast rays manually and then sample attributes at hit positions using PrimAttrib (it'll return interpolated values for point attrs). It's slow though, but sometimes can still be useful.
I'm attaching a simple scene to demonstrates this.

To access at Cd Attributes in COP :
In CHOP create Geometry and add your Geo in SOP, Attributes Scope will be : Cd
Use Pixel COP, red green blue will be the channel of the Geometry CHOP.

Pixel COP is slow, i don't know how we can have access to Point Attributes in VopCop ? (for bypass the pixel COP)

Kim Goossens published a tutorial on exchanging image data between SOPs and COPs.

Why my Houdini doesn't have Attribute for map? Or where is it?
