RTX 2070

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...

Re: PhotonGI cache

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...

Re: PhotonGI cache

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...

Underground

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...

Re: PhotonGI cache

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....

Re: PhotonGI cache

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...

Re: PhotonGI cache

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...

Re: PhotonGI cache

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

Re: PhotonGI cache

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...
