Re: Why Does Luxcore Support Materials Based on the GGX Model?

Why Does Luxcore Support Materials Based on the GGX Model? Why shouldn't we ? In case you wanted to ask why "doesn't": current Disney material uses a GGX distribution. I transplanted Microfacet Reflection from pbrt to luxcore How ? Where ? What does mean "transplanted " ? and the results did not me...

Why Does LuxCore Not Support the GGX Model?

I transplanted Microfacet Reflection from pbrt to luxcore and the results did not meet my expectations.
I'm using Trowbridge Reitz Distribution.

Re: I want to implement a standard surface material similar to arnold

I want to implement a standard surface material similar to arnold, like https://autodesk.github.io/standard-surface/ However, when luxcore performs evaluation, only one of the reflection and transmission can be calculated at a time. How can I implement multiple lobes like a standard surface? Just c...

Re: I want to implement a standard surface material similar to arnold

You could take a look at the disney material, especially https://github.com/LuxCoreRender/LuxCore/blob/2863718772213dd938913da4fff37b0c0ffaf49f/src/slg/materials/disney.cpp#L269 Yes, I'm actually learning the luxcore code, but the disney material in luxcore does not have the transmission effect. I ...

Re: sun linked to sky proplem

I'm doing an animation of the transition from sunny to rainy days, but I find that the sun of luxcore has no way to turn off the shadows, which is quite counterproductive. I set the sun's intensity to 0, but since sun is linked to sky, sky's brightness is also set to 0. If sun is not linked to sky,...

Without a test scene to reproduce the problem, it's impossible to fix this.
A traceback with more details would also help.
ok,I'm reproducing the problem.
