LuxCore

New Features since v2.6
  • BIDIRCPU can now use PhotonGI caustic cache to render SDS paths
  • Optimized the parsing of mesh light sources and it is now about 3x faster
  • Introduced (partial) multi-thread support in pre-processing of Light sources
  • Integrated OpenColorIO v2.0
  • Added the support for new TONEMAP_OPENCOLORIO tone mapper
  • Added the support for color spaces (Nop, LuxCore and OpenColorIO) to image maps
  • Added the support for color spaces (Nop, LuxCore and OpenColorIO) to constant textures
  • Added the support for color spaces (Nop, LuxCore and OpenColorIO) to implicit definitions of constant textures
  • Added the support for color spaces (Nop, LuxCore and OpenColorIO) to materials
  • Added the support for color spaces (Nop, LuxCore and OpenColorIO) to light sources
  • FILESAVER avoids to save the internal random image map (used by randomized tiling)
  • Updated to Intel Embree v3.12.2
  • Updated to Intel OIDN v1.3.0
  • Updated to OpenImageIO v2.2.13.1
  • Regularize coordinate system to solve some anisotropic related issue with glossy material (pull request #521)
  • UVRandomMapping2D now supports optional random rotation step parameter (issue #528)
  • LocalRandomMapping3D now supports optional random rotation step parameter (issue #528)
  • Introduced the concept of Scene texture image maps resize policy and the support for NONE and FIXED policies
  • Reworked the way alpha channel is computed for transmitted paths
  • Introduced the MINMEM Scene texture image maps resize policy
  • Updated to Intel OIDN v1.4.0
  • Added the support for Intel OIDN auxiliary buffers pre-filtering
  • Added the support for new pyluxcoretools MakeTX
  • Introduced the MIPMAPMEM Scene texture image maps resize policy
  • GPU out-of-core rendering now automatically disable Film GPU image pipeline to save more memory
  • Added the support for Film-only out-of-core rendering (CUDA-only) with property opencl.outofcore.film.enable
  • Added a safety check for infinite light source when HDR with invalid values (NaN, Inf, etc.) is used
  • Added the support to Intel OIDN plugin for enabling/diasbling prefiltering with .prefilter.enable property
  • Disney glossiness evaluation (for PGI, Albedo AOV, etc.) now checks metal and specular parameters
  • Disney glossiness evaluation uses now the square root of the value to align with the roughness of Glossy2, Metal, etc.
  • Added the support for image map filtering nearest, linear was the only mode available before (issue #545)
  • Albedo AOV reflections and transmissions can now be configured (mostly for denoising)
  • Avg. Shading Normal AOV is now coherent with Albedo AOV reflections and transmissions settings
  • Intel OIDN plugin now pre-filters Avg. Shading Normal AOV too
  • Added the support for Albedo and Normal AOV warmup for improved denoising with BIDIRCPU
  • Added the support for camera projection UV shape
  • Added the support for OpenColorIO Looks to TONEMAP_OPENCOLORIO color space mode
  • Added the support for OpenColorIO Looks to TONEMAP_OPENCOLORIO display mode
  • It is now possible to set the light source volume like with camera (for BiDir)
Fixed Bugs since v2.6
  • Fixed the reading of IES files on system with not-US locale
  • Fixed a problem with Python and Property objects initialized as double even if they were int
  • Python Property object now consider int data type always as a 64 bit value
  • Fixed a bug rendering black baked maps when using bump mapping and COMBINED type with BAKECPU rendering engine
  • Fixed a bug when rendering caustics over volumes with Caustic cache (issue #533)
  • Fixed a problem causing the initialization of multiple dataset accelerators in some case
  • Fixed a problem with incorrect alpha AOV values (issue #536)
  • Fixed a problem when using Add/Subtract textures with bump mapping (issue #689)
  • GlossyCoating is now a delta material if the base material is
  • Fixed a crash when editing light source emission
  • Added a work around to pyluxcoretools with PySide2 causing a std::bad_cast
  • Fixed a possible crash when editing a scene
  • Fixed glTF export to work with Python base64.b64decode()
  • Fixed a bug in Disney material causing bright edges
  • Fixed a problem with not-NULL transparent surfaces when the interior and the exterior volumes are the same
  • Fixed a cut&paste error in ImageMapStorage::GetDuv() (issue #560)
  • Fixed a problem with indirect light going trough objects with white shadow transparency in BIDIRCPU
