Re: Idea for an improved sampler

fair enough, if it's been tried and no improvement was found, no point reinventing the wheel on that one. In regards to the problems with the serial nature of MLT, it's definitely a limiting factor - while not quite the same, i've run into similar issues trying to implement hamiltonian MCMC in my ow...

Idea for an improved sampler

So, i've been getting myself familiar with monte carlo sampling for an unrelated machine learning project, and a thought struck me. One of the biggest issues with the metropolis light transport algorithm in unidirectional path tracing is the fact that it's not noise aware; it's good at finding light...

"A Simple and Robust Mutation Strategy for the Metropolis
Light Transport Algorithm"

looks like it could be a simple way to increase the performance with little overhead.

Re: LuxCoreRender v2.1beta1 released

found a bug - when using the bidirectional engine, enabling the samplecount AOV stops the sampler from doing anything - 0k samples/second, 0 samples, however it still shows rays/sample correctly. Not sure if this is a blender plugin specific bug, or a bug with luxcore itself.

Re: Simple scene, working on replicating my desk

I have the focal point on the center of the drawing, i'll try a small test render later with the focus on the glass instead. Thanks for the pointer. It's clear you're doing a super realistic pics there. you can also increase your specular deph to something between 16 -- 24 to get a clear glass. keep...

Simple scene, working on replicating my desk

Decided to really try and get the hang of a photorealistic workflow, ended up with this - it's simple, but I like how it's turning out. The pencil clearly need some work though.

I'm thinking of eventually expanding this to have everything on my desk, then maybe try to do a full room.

Re: LuxCore v2.1 proposed features

i would love to see roughness added to architectural glass, in order to do more realistic SSS shaders - using the translucent shaders isn't very accurate, and causes much longer render times compared to using architectural glass, textured transmission & a heavy scattering volume. Currently there's a...

Re: Dark side of the moon

i know, it was overkill for the scene - the scene started out as a worst-case scenario benchmark. A re-render using single scattering only took around 4.5 hours to converge.

Dark side of the moon

Long time lux user & lurker, decided that the new release was a good time to start getting more active in the community. So here's my attempt to recreate a classic image! I'm amazed at how much faster the engine is - only took 20 hours to render to 5% convergence using an underclocked fx-8350 on bid...
