LuxRender v1.6RC1 Release

Postby jeanphi » Mon Mar 21, 2016 5:02 pm


We are happy to announce the first release candidate of the 1.6 version of LuxRender.
This release features tremendous improvements to the new LuxCore render engine which is still missing some of the features of classic LuxRender but has gained numerous unique features to help artists creativity.
You can get a visual outlook of the new features in the wiki: shadow catcher objects, sky ground color, new image pipeline, much better nodes support in Blender, automatic blender materials conversion to name a few.
The Blender integration is not the only one to have seen huge improvements, the 3DSMax plugin has also been reworked and is now much better integrated, follow the development in the 3DSMax forum.

Note: LuxBlend is not yet compatible with Blender 2.77 due to the switch to python 3.5, you need to use a previous version of Blender or compile luxrays by yourself with python 3.5 dependencies

If you find any issue please report them in the forum or in our bug tracker. Note that the Blender plugin is now using its own bug tracker at BitBucket.

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:

I wonder why this is, py3.5 does not change any lux relevant part.
My Linux and OSX builds run fine with Blender 2.77 when done with python 3.4 !
Is this only true for windows ?

Anyway, i already changed my boost to be compiled with py 3.5 ;)

Hey guys, the issue with OpenCL on GPU producing black renders when textures are used is gone, thanks!
Meanwhile I have a new bug to report: object motion blur with OpenCL doesn't take into account shatter settings, meaning the amount of blur doesn't change, but switching to CPU makes it work.
