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.

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.

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?

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.

:) Got the external .crf working.
The dorfCurves.txt type formation works.
Only the blender exporter wont copy the crf file to exported scene 00000 folder.
It links the drive address that you set in luxcoreblend.
This is somewhat a bug, I'm going to fix it.

Re: Analog film simulation .crf file

Values are form 0.0 to 1.0. So, for instance, you can map red...

Re: A Dream machine

And use liquid cooling (closed loop is fine) for the CPU, it is so much better :!:

I'm on hold too because the have doubled the floating point units on the next generation of Ryzen/Threadripper and it could be a significative advantage.
