LuxCoreRender Forums

Hello!

I was wondering if LuxCoreRender would give even better results when using Linux versions.
I know some software performs better and is more stable on Linux. Has anyone compared it? Or what are your thoughts on this matter?

Linux may perform (a lot) better when using hybrid rendering (CPU+GPU rendering, enabled by default). The Windows scheduler is really bad, I can barely move my mouse when compiling Lux on Windows, no problem on Linux.
The same kind of problem may lead to a difficulty in feeding fast enough the GPUs when the CPU is busy doing rendering too. It doesn't happen on Linux but we have received some report about this problem on Windows. It is something I have still to check on Windows. It may be worth leaving 1 or 2 cores free on Windows to have the space to "feed" the GPUs fast enough.

For the rest, there may be some difference in code optimization done be GCC vs VisualStudio C++ but it is usually a minor difference.

Okay, I think I'll give linux version a try.

I managed to get Linux working, but after installing LuxCoreRender addon I get this error message. I guess it is related to my files location, but I can't really understand the problem.

It means that it is missing a library file (like a DLL on windows) and can't load it.
Can you test it with this zip file? https://www.dropbox.com/s/5d56jggyb0brl ... v.zip?dl=1
Remove the failed installation first.

I'd say this is expected cause libembree is not designed correct for stationary use.
Such will also happen if you use a dynamically linked blender ( selfcompiled )

There is a thread where i explained the issue.

If you want you can get a fixed libembree.
To make things short:
- get the libs replacement i pm'ed you.
- unpack and place in : /home/<your_userhome>/.config/blender/2.79/scripts/addons/BlendLuxCore/bin

If the issue persists, you have a dynamic blender and need the other trick described in the SteffenD thread or
get an official 2.79a/b.

Thanks for quick responses. I realized I had older version of Blender installed so I updated is to latest version. The first error is gone, but new error popped up.

Is that with the zip file I posted above?

Yes, I used the version You sent. Since I am very inexperienced with Linux, it may be, that I have installed something incorrectly.

I doubt it. The "install from file" button is enough.
I'm a bit at a loss what it could be. Maybe a version conflict with a pre-installed embree version?
