Re: CPU vs GPU shading

I made the observation, but had to increase min. epsilon by factor 500. It depends much on how the edges are connected in the shape. This glitches are often seen with GPU rendering after bolean operation difference.

Min. Epsilon: Metropolis, GPU Path vs CPU Path

Modelling a new ashtray I've noticed some glitches in view port render which have been removable increasing min. epsilon by factor 100. Now, testing Metropolis regarding sun light and glass windows I've noticed a glitch, dark line below second window from left, in the final render when using openCL....

Re: at rickyx, reason for investigation

Can you post an image of what you want to reach? I got this: Laser.png In interior design often I totally remove the window glasses. Often I don't need reflections or I just mix transparent with glossy using a fresnel. Well, my idea was to setup a fog chamber for tracing beams. But the beams haven'...

In the scene the effect started with a plane surrounding the room outside. 2018-09-22 CPU BiDir Sobol (2).png 2018-09-22 CPU BiDir Metropolis (2).png In the abstracted scene there still passes some light through the...

Sobol hides sun light through glass

With CPU BiDir, Sobol sun light does not pass through glass in some circumstances. To find the source in the scence leading to this effect took a while to be found. With CPU BiDir, Metropolis sun light passes through glass in the same circumstances. Also interesting CPU Path, Metropolis works too, b...

Re: first steps

In another quicktest I noticed that leaves at the top of the hedge look very green and wrong. Any tips on how to fix that? Nice trees in the background. But the very green leaves on the top of the hedge look like growing grass. Did you check the viewing angle? Are your leaves flat or 3d bend? Just ...
