Milestone 4.0.9

Enhancements

  • Reduced texture I/O for glossy reflection: For rays of type AI_RAY_GLOSSY, the differentials used to calculate texture sampling footprints have been improved resulting in generally larger filter sizes while still matching the requested visible detail. Texture sampling will now choose less detailed MIP levels when possible and will generally load less data from disk and do less work. (#3034)
  • Faster missing textures: For handle-based texture access via AiTextureHandleAccess(), the texture subsystem will not be redundantly queried once we have determined that a handle corresponds to an unreadable file. This can improve performance in scenes with many missing textures, which surprisingly can happen in certain production pipelines. (#3040)
