Re: How to imitate real world materials

Also simple node setup with glossy translucent material show strong scattering even with low roughness values. BR Glossy transluscent is kind of its own little world to be explored best starting with time and a sunny mood. I wouldn’t mix it with any other material. If matte is low tide glossy trans...

Re: Convergence AOV

I have tried a median filter in the past (I even wrote an imagepipeline plugin for it), but it falls apart once you feed it a normal scene. It destroys texture detail and creates unacceptable blur. I'm not saying it couldn't be improved with some additional logic/thresholds/feature detection or so,...

Simulation of Filter Algorithm, 2D

Acutally to remove a part of noise and to remove one pixel size fireflies without directly neighboured fireflies, filtering with math function median is fast and reliable and might be one of the better solution if fast rendering is required.

Re: Convergence AOV

Yet I found 2D post or frequently applicable pretty fast algorithm with adjustable parameters removing most fireflies and noise. I will post some pictures of the simulation soon. This time 2D.

Re: Direct Light Sampling Cache (aka Light cache part I)

Finally, I observed the dark circle areas are related somehow to use of area lights. With point lights I found DLSC settings, most important are, for this scene, search radius 0.1 and entry angle 0.1 degree. Rendering is ongoing, I will post the result this evening.

Re: Different exposure when rendering different parts of the image

All I need to do is make sure that Auto Brightness is disabled, right? This is right. I would render a preview, adjusting brightness manually in linear tonemapper during rendering and then stop and restart wirh final resolution. I am very curious how your rerender will top your already fantastic wo...

Re: Convergence AOV

Finally,
I found an approach to reduce noise and limit impact of fireflies in a quite practical manner. After a few further tests I‘ll send Dade my simple numeric simulation, with the math and conditions to check if implementation in LuxCore is feasible.
