LuxCoreRender Forums

I have one and am very happy with it. At full speed (slightly overclocked 1740 MHz) it sucks 140-160W Power, very efficient. Warning: The official Blender 2.79b required for LuxCore will not recognise an RTX in Cycles. That needs a newer build with RTX support (newer CUDA version) which will not run...

Maybe the issues come from the export/import? For example excessive scale in object space, or extremely large/small models, causing floating point precision issues? I just fought with this last week but now with a build from two days ago I cannot reproduce it :? Either I'm stupid or it's gone, anyw...

Thanky guys!
Always wanted to animate a test scene with two orange cars ...

Light leaks, that is light penetrating tight meshes, are a serious problem in Blender and Lux. In my main 3D app Cheetah3D this problem doesn't exist and whenever I port an interior scene with sunsky into Blender I have to put it into a Box for shielding, and the box has to be black or light will ev...

New animation. PathOCL, no PGI but OIDN. 200 frames á 3:50min. First attempt was with scattering volume but that took to long, will try that with Cycles again. Then I wanted to slow it down and scale it up but DaVinci Resolve failed me, so it's too fast now. Anyways, even without cache, animating w...

Mmmmm, this thing is going to be quite fast on GPUs, check the samples/sec Whoa, now this looks very promising, great work! I didn't expect this to come so soon and started some (non-PGI) animations over the weekend so I won't be testing it right now. edit: I have exposed the normalangle parameter....

The normal threshold is not exposed in BlendLuxCore. Should I add it, is it needed? Or is this just a very rare pathological case? B.Y.O.B., I think during the alpha testing all accessible parameters should be exposed. Then the users will find out what is necessary for tweaking and what can be hidd...

I just hope this won't end up like dlcs, great feature but unreliable because of unfixable splotches. I'm confident Dade will fix this too. :D . Maybe photon variance clamping to eliminate firefly photons? But it's possible the fallbacks will diminish the speed gain. Also glossy with roughness <0.2...

Just discovered that strong bump maps can throw off the cache totally.

After all, LuxCore is advertised with a big orange "Physically based rendering" as the first thing you see on the homepage. That may raise expectations ;) There is the rendering equation by J.Kajiya and I guess every algorithm that solves it without deviating can be called unbiased. Pathtracers, in...
