Variance Clamping

Variance clamping is an evolution of old radiance clamping and helps to prevent fireflies while preserving the colors of highlights much better.

Sky Ground Color Options

Example using a green ground color

The sky lightsource supports two additional properties:

  • Ground albedo (the brightness of the ground)
  • A custom ground color for the lower half of the sky

HSV Texture

The saturation of the image texture is controlled by a checkerboard texture

A new texture for hue/saturation/value manipulation was added.

LuxBlend

  • New, improved image map node (shows thumbnails, can select image from already loaded images in Blender or open a new one)
  • Renamed "Null" material node to "Transparent", can now use colored transparency
  • "Material Datablock" node to use any scene material in a nodetree (supports materials made in the "old" editor, too)
  • Use an OpenCL kernel optimized for live editing in the viewport (reduced number of kernel recompilations)
  • Ability to export to the new LuxCoreUI right out of Blender
  • Support for pausing/resuming of final renders

LuxCore Node Support

LuxBlend now supports node materials in LuxCore mode.
A new volume node editor was added as well and most nodes were reworked to provide a faster and more intuitive workflow.

New Light Groups Interface

The light groups interface was reworked and is now capable of live-editing during the final render.

Live-Editing of the Imagepipeline

The image pipeline can now be edited during the final render, making it possible to adjust the brightness, input pass and other parameters.

Transparent Film

A convenience function was added to import the RGBA_TONEMAPPED pass directly into Blender as the render result.

Cycles Scene Converter

A simple converter for Cycles to Lux conversion of materials and lights was implemented.
It is not very advanced, but for simple scenes it can provide a starting point to relieve some of the conversion work. The success rate depends on the complexity of the Cycles materials.
