Re: BIDIRCPU can now use PhotonGI cache to render SDS paths

Yes, i agree, bidir should be kept simple to use. A try and error approach works in a situation where you can tweak all other parameters in order to maximize speed. In a bidir situation, where you cannot tweak almost nothing, a try and error approach is uncomfortable because each rendering test take...

Re: Best noise reduction approach

Thanks BYOB, yes , we re rendering from command line. Do you think it's enough to enable albedo form the image pipeline or something like that?

Best noise reduction approach

\Hi, i'm struggling a bit with Oidn which always blurs important details form renderings. We tried by using multiple samplers but results are very similar one to each other. In the following image the main problem is the floor in the background which suddenly blurs. I know there are multiple tricks ...

Re: Specular reflection vs diffuse reflection.

The mixer test would be perfect if you would be allowed to use a fresnel function to blend the nodes. It cannot be a constant value (like it is in maxwell after version alpha) but a value which varies accordingly to the incidence angle. It is pure non technical speculation, but as I understand : IO...

Hi tokiop, thanks for your tests. The mixer test would be perfect if you would be allowed to use a fresnel function to blend the nodes.

Re: strange behaviour of homogeneous scattering volume

Hi Lighting freak, i think that the blurriness increases not because the mayor thickness but simply because the mayor distance between the upper surface and the paper behind. Try to elevate the thinnest sample at the same elevation of the thickest one by putting some coins below it; you should get a...

Re: Specular reflection vs diffuse reflection.

To be honest, we're doing these photo tests to have a solid base on which to align multiple rendering engines from a quality standpoint. Our rendering platform, Felix, currently uses Maxwell but we want to migrate everything to LuxCore. I knew about this reflection problem in Maxwell, but I hoped th...

Re: Specular reflection vs diffuse reflection.

I think this feature i very important for a rendering engine which states to put physical correctness at top of his priorities. But forgetting luxcores official goals i'm sure that this features would give luxcore the final touch regarding naturalism and image smoothness. Not even mentioning the fac...

Re: Specular reflection vs diffuse reflection.

The only way i found to get something similar to the correct result by using Maxwell is by creating two spheres with a 0.2mm offset between them; to the outer sphere i applied a transparent plastic and to the inner one a white matte. View main 600x600.png In Luxcore it should work in the same way. I...
