This page will describe the material and texture standards, formatting, and hierarchy in PS unreal. Asset naming follows the layout on the main art page.
In summary, Materials are set up as instances of a limited number of material masters, which reduces the shader calculations required for the game. These masters are:
- terrain material
- ceramic building material, ie. tile roofs
- normal building material
- generic level asset material
- weapon material
- character skin material
- character hair material
- character armor material
- particle material
- flora material
- fur monster material
- carapace monster material
Textures are mapped to several input types, and are being converted to the newer PBR (physically based rendering) material system to take advantage of the higher quality results.
Texture types are:
- Albedo, or diffuse maps (including an alpha layer)
- Normal maps
- RAM (roughness, ambient occlusion, and metallic) maps: roughness is in red channel, ao is in green channel, and metallic is in b channel.
- Height maps (typically only used for landscape elements)
- SSM (subsurface mask) maps: distinguishes skin from clothing for subsurface effects
- Tint mask: primary color mask in red, secondary color mask in green, skin in blue
