LuxRender v1.6 Release

Postby jeanphi » Mon May 16, 2016 2:27 pm


We are happy to announce the final release of the 1.6 version of LuxRender.
This release just fixes a few bugs compared to v1.6RC1 but features tremendous improvements to the new LuxCore render engine compared to v1.5. It 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.

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.

LuxRender v1.6RC1 Release

Postby ostry5 » Thu May 19, 2016 12:56 am

Released version still doesn't work on Blender 2.77 on Windows (I'm on win 10). I see that luxblend still contains Python34.dll and blender complains
about this dependency while trying to load pyluxcore.pyd

That was exactly the same thing I though when I noticed the python34.dll, but here on Win7 Pro 64bit, Blender 2.77a 64bit (Portable), it works fine. I do also expected an error message complaining about the Python version but it didn't happen.
I forgot to mention that at first startup of Blender with the LuxBlend add-on installed I noticed that it reported still the 1.6RC1 version, then I updated the LuxBlend in the User Preferences and the revision switched to 1.6.

I tried updating luxblend but with no effect, for me it looks like botched build. Funny thing is that when I went to source code repository, I found Python35.dll among the dependencies...

Edit: got build from 20.V This one works with my setup. \thanks

Could you elaborate a bit on this? i can't get luxblend to use the internal export type
my addon luxrender folder does contain the pylux.pyd
