Specular showing on alpha

Pope Adam

hey PC

I'm getting this problem in my renders. I've got this griffon masked out with an alpha, but for some reason, all of my alpha'd planes are only masking out the diffuse channel. I'm using max and haven't done anything unusual with my shader. How can i make this stop, to get a nice crisp clear render without this ghost reflection?

think i figured it out... deleted the flat blue background on my normal map PSD... totally vanished after that :P

that's weird. I'd just make sure any alphaed areas are also black in your spec map, and all should be well.

fixed with putting an alpha in the specular map to link to the gloss map channel.

Thats lookin sweet Adam. Pimp Hammer of Doom +9 attack, 5 x d20 and a save for crushing damage.

I know this isn't in PnP but the first render looks much better (apart from the ghost specular of course)

The specular looks a bit "flat" if you know what I mean. Like theres no spec map at all, just a straight value plugged in.

This is excellent! I was having the same problem, and finally fixed it.
