LuxRender v1.5RC1 release

Postby jeanphi » Sat Jun 20, 2015 9:36 am

Hi,

There has been a tremendous amount of work since the release of v1.4 and we are now very pleased to present you the first v1.5 release candidate. We're moving along quite nicely towards LuxRender v2.0 and we hope you'll enjoy that new release.
As for v1.4, LuxRender itself has not seen much changes but the new LuxCore rendering core has gained a lot of features and nearly matches classic LuxRender.
You can get a visual outlook of the new features in the wiki: major speed improvements, volume precedence, new materials and textures, volume emission, strands, better integration in Blender and 3DSMax to name just a few.
Paolo, Reality plugin author, has experimented more than 10x speed improvements with the new rendering modes: https://www.youtube.com/watch?v=b6fyJQOzfvU

If you find any issue please report them in the forum or in our bug tracker.

Thanks to all developers for their hard work and to the users for their feedback throughout the development process.

Please consider making a donation if you like our work and want to help us continue to improve LuxRender.

You can download packaged builds from our download area, or get the source from our mercurial repositories:
LuxCore: http://src.luxrender.net/luxrays/commit ... er_v1.5RC1
LuxRender: http://src.luxrender.net/lux/commits/tag/v15RC1
LuxBlend: http://src.luxrender.net/luxblend25/commits/tag/v15RC1

You'll find below the full change list since v1.4.

LuxCore new features since v1.4:

  • OpenCL micro kernels for improved performance and reduced pressure on OpenCL compilers
  • OpenCL tweaks suggested by nVidia to improve performance (general commonly accepted tweaks not specific to nVidia hardware)
  • new biased path render engine with more tuning knobs to trade between render speed and render accuracy
  • integration of Intel Embree technology for faster triangle intersection
  • vertex color interpolation for area lights
  • adaptive tile rendering with automatic stop condition
  • auto-linear tonemapping support
  • new irradiance pass with optional contour lines for lighting studies
  • accelerated Blender mesh convertion
  • add camera response support, metal2 fresnel parameter, blender procedurals in the built-in lxs parser
  • improved OpenCL Sobol sampler
  • new substract, blackbody, irregulardata, lampspectrum, fresnel (color, luxpop, sopra, preset), pointiness textures
  • image storage improvement to reduce memory pressure with large textures
  • new glossycoating material
  • new orthogonal camera
  • new volumetric cloud texture to simulate realistic clouds in the sky
  • add various interpolation modes to the band texture
  • new strand shape support
  • fixes to mix material
  • fixes to volumes
  • fixes to glass materials
  • fixes to lights handling
  • fixes to motion blur in OpenCL
  • remove hybrid CPU/GPU render engines

LuxRender new features since v1.4:
- add new LuxCore features to the luxcore render engine
- easier build on OSX and Windows
- fix imagemap texture alignment (1 pixel offset in some circumstances)

LuxBlend new features since v1.4 (LuxCore API unless otherwise specified):

  • proxy support
  • alpha transparency support
  • improved real time material preview (correct mix material, volumes, ... support)
  • light groups support
  • support for camera clipping planes
  • add support for hitpoint data textures
  • lots of improvements to the real time scene preview and editing
  • lots of UI improvements for consistency and robustness (a huge refactor of the code has been done for that)
  • improved imagemap handling
  • improved volumes texturing
  • improved motion blur support
  • add color ramps support
  • add particles motion blur support
  • fix visibility handling
  • fix camera shift support
  • add support for new LuxCore features (textures, materials, cameras, volumes, ...)
  • fix border rendering
  • add support for volume emission

Hi, I'm not seeing any options for volume light emission when in LuxCore mode on the LuxBlend included with this download. Is this still not available without the latest dev build?

Don't you have this option under Volume parameters section? If not, make sure you've updated LuxBlend correctly.

Btw. for some "demo files" on volume emission, check this link: https://drive.google.com/folderview?id= ... sp=sharing
(These are from my little tests in this thread)

Nope, no sign of that. After I installed Luxrender I completely removed my old LuxBlend folder from Blender before copying the new one from the LuxRender folder. I noticed that in LuxCore mode the material preview isn't working as well.

What OS/architecture are you using? Could you point to a Lux distro file you've downloaded?
