Color value for each polygon

[CinnamonMetal]

The class hou.polygon doesn't have a color() method. How can get the color for each primitive as a tuple in a mesh (python) ?

I think you just need to fetch it as a normal primitive attribute

floatListAttribValue(name_or_attrib)

http://www.sidefx.com/docs/houdini/hom/hou/Prim

using "Cd" as the attribute (make sure you actually have the attribute as primitive attrib, rather than points for example)

 

 

[CinnamonMetal]

curNode = hou.pwd()
prim = hou.Prim
for thePrim in prim:
    primColor = prim.floatListAttribValue("Cd")
    return primColor

As close to the above; although it errors ?

Yep, tons of errors in that. You can only return from a function, which you have not declared.

Here is my guess of what you might want. But be aware, the code will fail if there is no Cd attribute on the incoming primitives. So you may need to use hasAttribute before you attempt to retrieve the value.
 

node = hou.pwd()
geo = node.geometry()
for thePrim in geo.prims():
    primColor = thePrim.floatListAttribValue("Cd")

Yes, thank you  

Although what direction must I need to try first, to get the values as readable (rgb) tuples rather then this; 0.33311760425567627 ?
