The LuxRender has just released the first release candidate for the upcoming 0.8 version.
Changes since v0.7.1 (also check the new in 0.8 wiki page):
- New GUI options to save render on demand (most file types are supported), with or without separate light groups, statistics overlay, ...
- new glossytranslucent material, initially developed for better leaves rendering
- film response curves to emulate traditional cameras color response (some curve are for black&white films too)
- GPU acceleration for path tracing when sampling one light at a time
- render queue to process several files in batch mode from the GUI
- support for split vertices in mesh subdivision (mesh will no longer open up in the presence of UV/normal seams when subdivided)
- new light groups color handling for better accuracy when adjusting light color
- outlier rejections (this will eat slightly more memory and slow the render a bit, but the noise level will be reduced significantly)
- finally usable exphotonmap integrator
- new band texture to enable complex gradients
- new volume scattering feature atop the volumetric absorption introduced in v0.7 (only homogeneous volumes for now)
- much improved ply mesh loader (supports quads, texture coordinates, subdivision, ...) and export to ply for various exporters instead of lux native (faster export and loading)
- on the fly microdisplacement to allow very high subdivision depths without any memory impact
- lots of bug fixes and improvements
