Hello.
When I import a iges file from rhino the geometry comes into Houdini all black and I cannot get the colour to change. Does anyone know how to fix this. It's got to be something simple that I'm missing.
Thanks

Does it have zero length point normals on it? If so try just deleting them

Hi.
I figured out my own question!
To get the geometry to not show black in opengl, I added a color sop.
To get it to render, untick the Use Point color tick box in the surface panel of whatever material you use.
Job done.
