PBL specular full black still adds highlights
Exact same shader, completely black specular color. The first is lighting mode is Blinn-Phong:
And now PBL:
Y U NO not render spectacular highlights in PBL mode with black specular color specified?

Specular doesn't work the same way as the "old" shader models. Specular defines the reflectivity when the view angle is 0, so, this is intentional. The easiest way to dampen it is to increase roughness / decrease gloss, or switch to a non-PBL shader.

Thank you for the prompt response. I am somewhat new to shader programming and do not fully understand the PBL model or its implementation specifics in ShaderForge. I am confident as my skill grows and the documentation on the product matures, I can leverage the advantages of PBL. For now, I am sticking with Blinn-Phong which meets my needs and is easier to learn given the plethora of information on the technique on the net.
Thank you for a great product and I look forward with enthusiasm to its continuing development and release.
