TGA Physically Based Shader
A Physically Based Lighting CGFX real-time shader for Maya which was originally created to be used by our students at The Game Assembly for their 3D game projects. This shader uses a few different textures which differ from the traditional specular, gloss and reflectivity. For reference and discussion of this shader please visit this thread on the polycount forum. A big thank you to my colleague and friend Niklas Hansson whom I initially created this shader together with.
- A real life material based fresnel term that alters specularity and reflections.
- A substance texture to mimic how materials reflect and refract light in real life.
- A roughness texture to define a materials surface structure(smooth/rough).
- Image based lighting via a cube map for reflections and ambient lighting.
- Roughness controlled pre-blurred mip levels of the cube map for reflections.
- Blended Normals to give a subtle skin effect in conjunction with normal maps.
- Emissive Texture to fake emissive surfaces.
- Fully linear shading pipeline.
- A bundled cheat sheet image with color swatches for several substance values.
- Shadow Map(pre-baked) support fully integrated with the shader (This feature is experimental and only works with one direct light source).
- Transparency support through the Albedo texture alpha channel.
- Energy conservation between ambient light and reflections.
