Hi all,

I waited for last LuxeCore Render update for months and it’s been released several weeks ago.

For those not familiar with it, it’s a formidable, free open-source, spectral renderer. That basically means light calculation is not operated in RGB approximation like Cycles/EEVEE but with true physical wavelengths values. For example that enables accurate caustics or light bouncing from mirrors and lightning the scene a bit more.

LuxeCore is built with blender in mind and it’s very easy to integrate it. However it can be kind of painful to “force” it into the pipeline of a sufficiently advanced scene with a lot of textures to “transfer” and make compatible..

Here is my problem : in my scene, LuxeCore crashes and I get a crash log that I paste here

Luxecore_Crash_Log.crash.txt (115.8 KB)

I have no problem in other .blend.. If anyone can help me with it ? It’s hard to find documentation on the web..

And, just for the ones who don’t know the LuxeCore capacities, here is a comparison, 1st is Cycles with caustics enabled -cpu+path guiding- , 2nd is LuxeCore in same time limit.

I can only advise to at least try and play with it, this is actually impressive

Not sure about the crash you are experiencing, but I just want to say, LuxCore is not a spectral renderer, it’s also RGB. Spectral rendering also doesn’t help with caustics either. LuxCore’s caustics capability mainly comes from its bidirectional path tracing/light tracing, a direction Cycles rejected for making its light path etc. functionality straight forward to keep.

Octane is spectral though.
