A little Enigma

What do you think, how does the object of the scene looks like?

Re: destructive denoiser

Just a guess: random sampler with adaptive set to zero and maybe uniform light strategy. There are different kind of random pattern, real random does not care about human favour for order. Real random can lead to clumpy noises, but human expect well distributed patterns. A well distributed pattern m...

Off topic: Dark Energy

In my opinion a surprising article for people interested in physics or philosophy.

Re: destructive denoiser

Isn‘t it a question of the right balance in a picture? If I think about colors and brightness I get several conclusions and one of them tells me a bunch of equotions. Since photosensitive silver plates it has been a quest for the perfect lightening. Don‘t sit in the sun for a candle light dinner. Ho...

Re: destructive denoiser

I'm gonna do some comparisons, but first. Just to illustrate how "good denoising" can you get with simple luminance noise reduction in lightroom vs default luxcore denoiser which eats a ton of memory and can only denoise properly clean areas of the image. BTW the only areas where denoiser did a sma...

Anyway, this thread is not about instancing, it's about film memory usage (at least I assume that it is causing most of the issues).
Thanks for the explanation, which makes sense.

I forgot to ask, what is about light groups? Does memory usage grow with their number?

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

What if there were an individual cache radius for each light source, depending on the volume of a path render with depth 1? This might be done even recursively, starting with a large radius, stopping at a maximal number of chaches per visible scene and light sources. What is "the volume of a path r...

Re: Luxcore and memory

To stress memory usage a bit a setup a test scene with 250 trees with particle system. I don't see much unexpected memory usage nor with opencl path neither with opencl tile path. a) In memory it's still just one tree not 250 if it's in the particle system. b) But I guess it is because cycles is mu...

Re: Luxcore and memory

To stress memory usage a bit a setup a test scene with 250 trees with particle system. Thanks to B.Y.O.B. I have been able to reduce time creating a tree group. Most tricky thing is the orientation, I think the behaviour of particle system regarding rotation is strange for a long time. One has to ro...

Re: LuxCoreRender v2.1alpha3 released

Does anybody know how to use transparency for image texture materials with luxcore blender addon? (I know one can chose image's alpha chanel but I don't mean that one.) Great! Thank you much B.Y.O.B.! Sometimes one doesn't see the wood for the trees: Foresting.jpg and animated: https://youtu.be/gnm...
