Re: render and viewport show different results

Another notice: Emission material emits light only in one direction (normal, while backface is black) which makes it cumbersome when used on flat (non-solid) 'twisting' geometry. 'Solidify' fixes this, but with 'Rim' on, is more than doubling the number of lights. eg emitter_flatbad-solidgood.jpg I...

Re: low cpu and gpu usage

I am observing same behavior, as if no CPU cores are used with Open CL (or something alike). Also with Standalone. It's only happening with the 'Azure' latest build . Are you sure ? I did this test: 1) download https://github.com/LuxCoreRender/LuxCore/releases/download/latest/luxcorerender-latest-w...

Re: Clouds

Atmosphere looks great!
Do you intend to go for the full environmental & atmospheric synthesis (inc. Rayleigh scattering)?

Thanks & keep it up!

Previous 'cores' (up to 09.10.2018* - posted in forums) work fine.

*edit: correction on the 'core' date

Re: DLCS Explained

Are there any specific papers which were used as a basis? Nope, it is original work. read the vray adaptive lights It is loosely inspired by this but they are (probably) using the photon map to extract the data while I have to build everything from scratch for obvious reasons (I don't have a photon...

Re: metropolis CPUvsOpencl

Metropolis The metropolis sampler is an "intelligent" sampler that uses the Metropolis-Hastings algorithm and implements Metropolis Light Transport (MLT). The metropolis sampler tries to "seek the light". This makes it a good choice in almost all situations. It does this by maki...

Re: DLCS Explained

Are there any specific papers which were used as a basis? Did the fast run again... (a short overview): Since i know appleseed 1.7 has (had?) Light Tree sampler (WIP) ~ similar to DLSC, i Started with Petra's GSoC 2017 with AppleseedHQ which lead me to Efficient sampling of many lights (@ompf2.com)....

Re: Strange black zones

Smooth Shading issues.
Either set to it to Flat, lower Normal Angle or add supporting Edge cuts/loops to the mesh.
