PBR Effect

These shaders mimicks PBR using standard ones.
You have two shaders one for static models and another for animated models like characters.

You need these textures in the material editor in that order :
- diffuse = diffuse map
- normal = normal map
- specular = inverted roughness map colors
- metalness = metalness map
- skybox = skybox map

Once exported your maps from a painting software , Invert Roughness map colors in a painting program.


There is some shader variables that you can tweak :

//Reflection power : 7
outcolor = mix( outcolor , ( texture(texture4,cubecoord) * outcolor * 7 ) ,color_metalness ) ;

//Color correction : 0.07
outcolor = ((outcolor + 0.07) * (1-color_specular ) ) ;
