LuxCoreRender v2.3

Since there was no current OSX version of LuxCoreRender i decided to take the quest to compile it
and learned alot about “static linking” on OSX but finally it worked out.

So here is the current github version. Should work on macos 10.13 and greater.

LuxCore 2.3alpha0

Would be great if you guys give it a good testing.

For the denoiser to work you have to give it a litte “chmod 755 denoise” from the terminal in
/Users/‘yourname’/Library/Application Support/Blender/2.81/scripts/addons/BlendLuxCore/bin.
replace ‘yourname’ with yours and adjust your blender version.

Wow this is impressive. I used this renderer 2007 and I am pressed how this runs now directly inside Blender.

denoiser still has issues to launch after I did chmod 755 denoise in side bin folder.

thank you !

Too bad it’s not building photongi for me :frowning:

@u3dreal I can’t get it working on my MacBook or iMac. Blender 2.81 crashes on checking the box in Addons. Any ideas? Would love to test.

Hi all… could you run blender from a terminal ? just cd to Blender.app/Contents/MacOS and type
./Blender … that should give you a terminal info about what is going wrong.
Post it here.

I just tried the version on my website on another mac. its running.

Can anyone confirm with this scene plz ?

Make sure to uncheck the intel device when running OCL !!! It crashes almost every time with normal scenes. Small scenes might render.

maybe you need cuda installed to use ocl with nvidia cards … i don’t know … hav cuda installed everywhere :slight_smile:

Very first caustic baking and glTF export for SketchFab: https://skfb.ly/6PzuS

As far as I know, it has never been done before. The baked map alone is quite a beauty:

For reference, this is the original rendering with LuxCoreRender:

out of curiosity when

whay are lights so agressive in Lux?
I turn of the world and the light then works so drastically overexposed
adjusting also the multiplier or color has little influence

Cycles

Lux world off

Lux lamp color 0.001

This would be a combination of two things:

  1. At the moment LuxCore uses an automatic tonemapper, so turning off the sun/world will have it try to keep the same final brightness in your image. I recommend setting it to linear under Camera settings.

  2. The Sun/Sky lights in Lux assume the same strengths as our Sun/Sky. Most lamps have a 10-100W power, and if placed outside in daylight would have little to no effect on lighting. This comes up more if your using the linear tonemapper and add a sun/sky to a scene lit with normal lights.

You have to turn that off or change gain.
It was strange for me when I started using Luxcore, but it kind of is nice. When I’m doing caustics in a dark room it’s ‘pumping up’ brighntess to make even small caustics visible (without banding effects), just like our eyes are adapting to the brightness.
