Modifing the Standard Shader (specular setup) and Multiple UV set.

Questions & Answers
1

Hello,

As you know the Standard (Specular setup) used in Unity by default is using the Alpha of the Specular file texture to define the glossiness. is there any way to change the shader to just use them separately in 2 different 8 bit PNG file that could be more optimized than one RGBA file ?
(I also got trouble using the Alpha from Substance Designer.)

And also, i want to use an Occlusion Map, but i want to define the UV Set 1 to be used instead of the uv Set 0.

Making some modification of that shader look’s so tedious to me as i’m just a 3D CG artist not a programmer.

You will have to edit the shader thrugh code.

For a CG artist Shader Forge Unity Asset Store - The Best Assets for Game Making Is a great pickup, this will allow you to create shaders with node based interface. It’s easy to use and will let you create the small modifikations your personal projekt needs in shaders. Shader Forge will allow for all of the modifications you ask for above without a lot of hassel.
