Re: Direct Light cache: how to avoid splotches?
I mean according your explanation here user will not have to worry about such kind of scenario : hard to reach light or big scene (view) small scene (view). This fix/improvement is more about the "normal angle" parameter and problems with light sources at glancing angles, in particular wh...

Re: DLS and material settings
I think the direct light cache still uses light sources with direct light sampling disabled. Maybe this could be considered a bug in the direct light cache? Yes, it had no harm but it was a waste of time so the light sources, with DLS disabled, are now skipped when filling DLSC information. By the ...

Re: Direct Light cache: how to avoid splotches?
This rendering explains the source of the problem: prob.jpg Triangles have normal interpolation and, often, the line between "day" and "night" falls in the middle of a triangle and it is due to the interpolated normal starting to point "away" from the light source. Now,...

Re: Usability and Luxcore workflow streamlining ideas
Also, some sort of luxcore ubermaterial (preferably metalness+roughness) should completely replace matte,glossy,metal,glossy coating and glass materials... ideally all matterials except specials like carpaint(which should also include flakes) and some easy to set-up skin material. Materials is a bi...

I sent you a PM with the scene. About the carpet on the floor I confirm I used a matte material Thanks, going to check but I have the strong feeling the problem is in the impossibility to have reliable cache information over the carpet (the particle system for hair simulating the carpet will likely...

Re: Direct Light cache: how to avoid splotches?
And what's up with the spot made of bright pixels here? Related? The first step when checking a DLSC related problem is always to switch max. path depth to 1 so you will see only direct light sampling: prob1.jpg It becomes quite evident that at glancing angles the information of the cache are not c...

Re: Direct Light cache: how to avoid splotches?
Isn't this always the same bug? I mean visually it always looks like the MIS issue with caching, or is it something different? Only if it is glossy and I asked before (https://forums.luxcorerender.org/posting.php?mode=quote&f=4&p=8053#pr7607) to redo the test with mate material so I assume ...
