Re: CGI tech news box

Ok, so I got it, and it's the denoiser from Declan Russel just made into addon. ... A kind soul would do like this: troopy28/OptiX-Denoiser-for-Blender (@ GitHub) then continue or better, start in denoiser specific thread... (i get you're passionate ;) but please, just move on - let us stay on topic)

Re: How to imitate real world materials

Let's assume I've a real sample in front of me. How would you test whether is representation in luxcorerender is right? I can't reproduce the lighting conditions of my appartment easily (quickly) in blender. For starters you create a controlled environment: a studio or a lab (ie. Cornell Box ). You...

Re: Light pass through solid object

i'd say it's precision issue mixed with bad values and inadequate scene construction Thanks for your input Kintux ! if this didn't lead to performance (speed) issue i'm more than happy with that ;) If i understood correctly, issue was with light leakage - so i simply applied Solidify modifier to Sp...

b1.png b2.png bump_lines_2.png Works fine - you got your UV mapping rotated by 90°. So, maybe it's this UV map orientation that's buggy? I would imagine, no matter how the map is oriented, resulting effect should always depend on bump and lighting properties. Bump_OK.jpg Lighting: Sun&Sky, Tonemapp...
