Milestone 4.1.3

Enhancements

  • Faster AiPerlin4: The 4-dimensional Perlin noise function AiPerlin4() is now about 1.5x faster. (#3777)
  • Faster bump3d: The bump3d shader now makes 25% fewer shader evaluations, which can reduce render times specially when using expensive procedural maps. (#3804)
  • Faster lights: Non-motion blurred lights are now a few percent faster to render, specially in scenes with many lights. (#3791, #3792)
  • Reduced per-object memory overhead: Ray accel structs now consume a few hundred KBs less memory, which can add up to hundreds of MBs saved in scenes with thousands of objects. We also lowered peak memory used in certain situations. (#3772, #3778, #3783)
  • overlay_mode in utility shader: We have added a new overlay_mode parameter to the utility shader which allows you do overlay wireframe on top of the regular color and shading modes. This can be set in the kick command-line with the -om command. (#3800)

Incompatible changes

  • Behavior of standard.specular_rotation changed: The specular_rotation parameter in the standard shader will now continuously rotate in the same direction when provided values outside of the [0,1] range instead of switching direction. (#3786)
  • objwire utility mode removed: With the new overlay_mode, the objwire color mode in the utility shader is now redundant. The same result can be achieved with -cm obj -om polywire. (#3800)
  • Hardcoded name of options node: The name attribute of the options node is now hardcoded to the string "options" and cannot be redefined. Calls to AiNodeSetStr(AiUniverseGetOptions(),"name","foo") will not have any effect. (#3817)
  • Removed shader_timing_stats: The global option shader_timing_stats which was used to report fine-grained timings of certain shading operations has been removed. The accompanying diagnostics AOV "texturetime" has also been removed. This both removes a bit of overhead and simplifies the internal logic. (#3818)
