1. Shader in Unity: using alpha as specular intensity and diffuse as specular color, could it work?

   

   Topic by Kyalie · May 2020 · Home› Coding, Scripting, Shaders

   Hi guys! I've been in the industry for a while but never had much love for poking around shaders settings and such. So when it comes to properly explain to our shader programmer the kind of result i would like, i end up not being sure if it makes sense at all. What i'm trying to achieve for our stylized game is to use the…

   Using the RGB channels from the diffuse as specular color for the highlighted parts (like how in 3ds max you have specular level (black and white intensity) and specular color (RGB, color)) Example, here the lighter version is specular only, with the highlits being rather desaturated, the more contrasted one has its…

   Just tell them what you want control over in the shader and they'll sort the rest out You can use any channel of any texture to do anything you want in a modern shader and how they're packed can have a huge effect on quality and cost so it's best to let the programmer worry about that.

   An alpha channel will work well for intensity. I'm not sure I understand the second part, you can't get color from the alpha channel if that's what you mean? I suppose you could make a color property in your shader that gets multiplied with either the specular intensity or a mask created by a remapped specular intensity.…
