Hi guys,

Was dabbling with the material shader builder in Houdini 14 and looking through the Surface Model node, there doesn't seems to have specular angle in it, not like in Houdini 13.

Did they entirely removed the specular angle option or it's just shifted to somewhere else or rename it to something?

thanks

What used to be the ‘angle’ to control the spread/width/roughness of the highlight is now the ‘roughness’ parameter. It is normalized to 0 - 1.

Although I've found this not to be consistent across all nodes. The surfacemodel does expose angle when choosing phong, blinn, cone. With GGX it shows roughness as the parameter.

The Mantra surface node uses roughness across all reflection models.

Ahh, I see. No wonder I couldn't find it. Cool! Thanks man!
