shaders - lighting on specular channel?

[legacy-Gbro]

I've been messing with shaders for fun and have run into something - I can't seem to get lights to affect the specular channel of the shader at all. The specular pass is allways unlit. Is there any way to get around this?

[legacy-Wackywack101]

yes i had the same problem. Just duplicate a shader and change the textures for it to the ones u want.

I've got a stupid question. PerformLightingOnSpecularPass is set to True right?

[legacy-Gbro]

I did try that. It doesn't seem to do anything in the editor (the specular texture stays fullbright) and UDN's shader description says that the option is not used.

Of course I could be wrong, seeing as I have not tried this in game yet.

I don't think Shader passes are affected by ambient lighting.
Probably an optimization for the sakes of performance.

this is true...a pitch black wall with a shader will still shine...it looks kinda weird

Darken the texture(s) that you use for the spec map. It will give it a better look. In photoshop I usually put a multiply layer filled with black at 60% opacity or so to darken them. Just need to play around with how dark they are to get the look you want.
