ludus::content::scene_format::MaterialRecordV5¶

Struct

Version 5 material: version 3 terms plus alpha coverage. A masked surface discards fragments whose base texture alpha (straight, unaffected by sRGB decoding) is below AlphaCutoff; an untextured masked surface is fully covered. Coverage applies to both rasterized views and transport rays alike.
