Here is the latest release announcement for LuxRender 1.6 from the LuxRender forum:

Hi,

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.

Guys you render looks really interesting i plan to integrate it in my pipeline. Good job guys keep doing it.

3

Thanks to everyone who worked on this release.
Probably interesting for the Blender people:

4

Congratulations on a great release and thanks for sharing!

Is there any chance NV GPU cards will be supported on Linux, ever?

5

I think that’s up to Nvidia (and their OpenCL support).
But I never heard that it does not work before?

6

I have had no luck using nv GPUs i had so far, at least i have a feeling they were not involved in rendering which would be endless process compared to Cycles. List of supported GPUs does not mention Nvidia for the Linux too.
Could be i do something wrong or simply expect miracles.

Will try latest release.

Thank you for your time answering.

7

There is definitely people using Nvidia GPU’s on Linux. Try to use the most recent drivers.
Even my poor Intel integrated graphics can sometimes work if the scene is simple enough
The page you’ve linked just list some known to be working systems, but it not an exhaustive list.

8

I had the newest drivers directly from nvidia’s site with OCL support they provide for Linux every time i tested Lux; this shouldn’t be an issue.
Thanks for the support, i thought nvidia on Linux might be excluded as such looking at the table…

You can test if OpenCL works correctly with LuxMark: http://www.luxmark.info/
It should list the devices it can find.

@eppo, What Linux distribution do you use?

If it is ubuntu based, install “ocl-icd-libopencl1” package. If the package is already installed, you reinstall the package.

Edit:
Note that there is a package called “nvidia-libopencl1” which can lead to conflicts. If you have it installed, you uninstall that package, and reinstall “ocl-icd-libopencl1”

So in short, you need to have installed “nvidia-opencl-icd-XXX” (where XXX is driver version you have installed) and “ocl-icd-libopencl1”

Thanks YAFU, i really do not want spam this thread with support related things, i’ll try again and move to tech support.

12

Cool thanx for sharing !

But i have two problem, How to render UV in luxrender ? and the other for light is tricky so what mean gain and importance cause i can’t control the intensity?

13

@threedslider, did you mean uv image maps or something else?

Gain is how much brighter a light source is compared to another, however by default the tonemapping will be set to ‘auto linear’ which adjusts itself based on light brightness. Try switch to linear instead and then adjust the lights :slight_smile:

14

Ok thank you, light is resolved. For UV yes i mean to uv images, with or without nodes ?

15

Wow… lot’s of changes, congrats on release and keep it up! Great job, sincerely thanks!

16

2D image textures use UV mapping by default.
What exactly are you doing and what does not work as expected? Can you provide a screenshot?

17

Crashes immediately on OS X when hitting Render, or switching to rendered view.

There is a screenshot :

Any idea from that ?

It looks like you didn’t save the image to disk.

20

Whats this setup ? Hackintosh ? Could be a simple driver issue then. Also use at least 10.11.3 or newer.
