With the introduction of Physically Based Shading (PBS) to CRYENGINE, it is important to adhere to how we configure our materials & textures to get the correct look & feel from every surface in the game.
To assist you during this process we have developed a set of debug views to investigate how your materials & textures are setup.
This CVar has 9 modes that cover the specifics of the PBS render to ensure that you are configuring everything correctly.
r_DebugGBuffer = 0
Off, normal view mode.
r_DebugGBuffer = 1
Shows the world space normals of all assets in the scene.
r_DebugGBuffer = 2
This debug view shows how rough or glossy surfaces are. Note how the reflective sphere in the scene is pure white.
White = glossy, Black = rough
r_DebugGBuffer = 3
This represents the Specular Colour of the material.
r_DebugGBuffer = 4
This shows the albedo of surfaces which was previously known as diffuse map.
r_DebugGBuffer = 5
Grey - Standard, Yellow - Transmittance, Blue - POM Self shadowing
The Vegetation & HumanSkin shaders have the Transmittance properties active by default.
r_DebugGBuffer = 6
Shows the translucency values set on assets in the scene. (Black = none).
This is controlled through the Transmittance Colour set in the materials shader params.
r_DebugGBuffer = 7
Sun Self Shadowing
Displays the self-shadowing of material that use Offset Bump mapping or Parallax Occlusion Mapping
r_DebugGBuffer = 8
Displays in red and yellow, any asset that uses SSS. The brighter the colour, the higher the SSS index.
The SSS index can be set in Illum and the HumanSkin shader.
r_DebugGBuffer = 9
This view helps you understand if your specular colour is reasonable range.
- If your specular colour is too low, it will be tinted Blue.
- If your specular colour is too high for an dielectric surface but not yet in the metal range, it will be tinted Orange.
- Pink reveals colored specular which is not yet in the metal range. This is only valid for oxidized (rusted) metals.
