Hello guys,

So… I'm trying to add an attribute to a geometry, in the primitive level.
I tried it with an OBJ I downloaded and I got: GeometryPermissionError: Geometry is read-only.

So I tried again in a simple BOX node I've just created… same error. Cannot seem to add attributes to geometries.

My line of code:
geo.addAttrib(hou.attribType.Prim, ‘intensity’, 0.8)

What's the catch?
Thanks,
Francisco.

Does that error happen when you run it from a Python SOP? Or where are you running that code?

This is what I put in a Python SOP, and that worked for me:

node = hou.pwd()
geo = node.geometry()

# Add code to modify contents of geo.
# Use drop down menu to select examples.

geo.addAttrib(hou.attribType.Prim, ‘intensity’, 0)

Thanks a lot! That worked for me too!
