Re: LuxCoreRender Project wants you!

Unit tests are an automatic testing procedure usually intended to verify the functional of a single feature (i.e. a single part of the source code). They are particular useful to catch regressions (i.e. bugs introduced with new features). They are supposed to be run at every commit of new source cod...

Re: LuxCoreRender Project wants you!

One of the problems of current unit tests for LuxCore is that they far exceed the the max. time available on Travis-CI. Run all of them on an average machine, requires many hours. We would need a dedicate server to run the tests non stop but we are lacking one. P.S. as end result, even if we have th...

It should be possible to use the Alpha channel to mask the background :idea:

lol, so no one ever got ahold of octane source to prove it was lux and he was just another (sadly all too common) open source guy who wanted to change the license to get paid for "all his" work, and kill off his open release(s)... regardless of everyone elses' years worth of contributions, and in t...

Sometimes it is not clear to me what is meant to exterior or interior, e.g. for a plane a 2D object with no volume.
You can not use a 2D object if you want a correct volume rendering, just use a slim box if you need a plane.

Re: Test scences GPU Path vs CPU BiDir

In the past I always had the impression that LuxCore Bidir can in fact render SDS paths, however they converge very slowly. Nope, it is like rendering caustics of a point light for a path tracer, it is just not possible (because the point light is a not intersectable light source so it can not be h...

Re: DLCS test

Why DLCS lighting is so diferent from log power/power strategy ? it deliver so much light There was a bug in area light source power computation (when the using power/efficiency parameters) causing power light strategies to erroneously sample only the soft area light outside the windows. I should h...

Re: Test scences GPU Path vs CPU BiDir

I haven't yet read the discussion but are you aware that SDS (Specular-Diffuse-Specular) paths can not be rendered by a normal BiDir but they require BiDirVM (or something equivalent). Note: a volume scattering point is considered a Diffuse path vertex (i.e. "D") while a glass intersection point is ...

Dade, why can't we specify exterior volumes for light sources?
I never tough to the implication, it is not required for Path tracing but it is for BiDir.

Re: DLCS test

I'm looking into the scene but before to start I'm checking a strange problem I have when exporting the scene in text format.
