Selectively Metropolised Monte Carlo light transport simulation https://cs.dartmouth.edu/~wjarosz/publications/images/bitterli19selectively-teaser.jpg For this indoor scene lit by a sun/sky environment emitter, path tracing resolves most of the lighting well, but introduces high variance in the ref...

Re: pathOCL turning singlesided meshes transparent

I think it's precision issue, starting with huge plane/boundary to satisfy the need for horizon... can you remove the big stuff from your scene and check again? There is no ocean mesh anymore (it's disabled from rendering) what you see is just ground color set in sky shader Even so, it's in the sce...

Variance-Aware Multiple Importance Sampling - Jaroslav Křivánek Many existing Monte Carlo methods rely on multiple importance sampling (MIS) to achieve robustness and versatility. Typically, the balance or power heuristics are used, mostly thanks to the seemingly strong guarantees on their variance...

Re: Environment lighting results different by cpu and opencl

You got coplanar faces which are causing an issue. The room floor and the plane (ground) are located at same height (0).
Either move one up/down or cut out a whole from the plane.

Re: infinite plane

imo, Iray has it best (especially for architects) since ground and more is being part of its Physical Sky

Re: Material Null generates Visible Edges and Intersections

The problem is quite easy to explain: the eye ray hits a front face however it doesn't detect the hit with the very near (on the edges) back face (due to numerical precision). The result is a volume segment between the front face and the far camera clipping plane instead of between the front and ba...

:D You're taking good care of both and they both look great!
Really appreciated.

Re: Material Null generates Visible Edges and Intersections

I don't know how Blender works but are you using an array of cubes instead of a single big cube :?: cubes.jpg In this case, you are going to have a lot of problem with all the overlapped faces, (lack of) numerical precision will do a mess of your scene. Why aren't you using a single big cube ? Even...
