Fixed

• Some black artifacts when rendering with depth of field.
• DynamicPathTracingSceneGenerator.reset not correctly resetting the class resulting in errors when calling "generate" again.

Changed

• Materials to use a texture instead of uniforms to cut down on max uniform errors.
• SUPPORT_DOF no longer needs to be explicitly set and will be toggled automatically based on the bokeh size parameter.
• Removed direct support for environment blur with addition of MIS. Instead use BlurredEnvMapGenerator to preblur an environment map.
• Antialiasing jitter is now performed per ray in the shader instead of via camera position jitter for improved AA.
• GRADIENT_BG define option to FEATURE_GRADIENT_BG

Added

• Support for "matte" material flag.
• Support for Multiple Importance Sampling for the envionment map and an associated "FEATURE_MIS" flag.
• BlurredEnvMapGenerator to blur environment maps.
• Support for rendering transparent backgrounds.

Removed

• Support for gradient environment colors. Use a DataTexture, instead.

New Demo Features

  • Use EnvMapGenerator to blur the environment maps.
  • Add support for setting background alpha.
  • Add new environment map options.
  • Add floor opacity slider.
  • Add support for "matte" materials rendering as transparent.
