Re: Light strategies and importance change lighting

BCD spikes removal option without the denoiser How do I set this up so that the denoiser only effect the fireflies? It is an option I have to add but it should be pretty easy. I have added the support for running BCD spikes filter alone, decoupled from the denoiser. It can be done by setting the ne...

Re: Realistic simulation of camera and laser

As part of this, I need the camera to act like a physical camera. It needs to simulate an actual sensor surface that will register pixel illumination when directly struck by a laser (or other light source, but the laser is the most crucial). I haven't gotten good results so far. "Hitting" the camer...

Re: Problems with specular reflection and homogeneous volume

When using Path, scattering is seen between the light and the mirror, starting from the light source. I.e. the cube is ignored completely. It is just normal and expetect, path tracing is not able to render caustics of not intersectable light sources (like point, spot, lasers, etc.). If you replace ...

Re: When is principled shader coming out?

Side note: if someone build a pre-made set of nodes working like a "uber-material", it could be exposed in BlendLuxCore like a single native node (i.e. some kind of macro nodes) and exported, under the hood, as the aforementioned set of pre-made nodes.

Re: Usability and Luxcore workflow streamlining ideas

I know I could appear as a stupid but I can't really understand the difference from a distant light and a sun light. It is HUGE (in Lux context): just try to render a glass sphere on a plane (better if with BiDir), the sun will cast a caustic while distant light doesn't. Distant light emits all par...

Re: Direct Light cache: how to avoid splotches?

Please Dade can you test the new code with AMD and my problematic scene here ? : https://forums.luxcorerender.org/viewtopic.php?f=5&t=675&start=10 It is working fine for me (but it was also before with my Linux + very old (stable) AMD drivers I never upgrade ... because they work). To test the new ...

Re: Light strategies and importance change lighting

No without some type of warmup with rejection of samples during that period or some additional memory storage. A solution that may be worth trying is the BCD spikes removal option without the denoiser part. It uses a samples histogram (i.e. the additional memory I was talking about) to reject sample...

Done, this is direct light only:
Impressive :geek: what are the DLSC settings for this ?
The defaults, I only raised the warmup samples because the default value (12) is really low. I'm thinking to rise the default.

P.S. for the record, it is a scene with 11,000+ light sources.
