How do I mask the specularity in models? Diffuse and displacement have input slots for masks, but not spec as far as I've seen.
You know, I'd forgotten that this wasn't implemented. It wasn't quite as straightforward to do this as the others when I wrote the Default Shader, and I must have forgotten to finish it up.
There a few ways you could work around this, but I can't think of anything that's really ideal. A safe bet is to mix between two copies of the Default Shader - one with specularity and one without. You would mix between them with the Merge Shader. Other options are probably more complicated, especially if you're using opacity maps.

Thanks, Matt. Ill give it a shot and post the result.
ignore my last post ;)
What last post? Have you figured out how to add a spec mask to model shaders?
No, sorry.
Has anyone worked out a way to mask specularity on models?
Come on shader geniuses: does anyone have a soolution for the missing ability to mask specularity?
Or how about a mask for reflection: I'll turn off spec and use that if it will work, I just don't want an evenly highlighted model. Any method that works will be acceptable.
Hi there,
maybe you could try to connect your specularity source,a default shader
or the reflective shader i assume,to a surface layers child layer port and
control it via coverage and break up.

Yes, this would be the way to go for now.

I managed it with Matt's suggested merge shader; it works. I've used the blend version, but I'd like to see which renders better and faster. Any ideas about the relative quality and speed of these methods?
I'm afraid I don't know what would yield better quality or speed, but in my experience the Merge shader is a bit trickier to fine-tune than a simple Surface Layer or other Distribution Shader.

Yeah, it took a lot of trial-and-error before I got it right, but the result is fairly simple and looks nice.
