Hello all, I did a comparision of two almost equal setups. Both are using the same scattering volume definition but one with a perfectly polished surface and the other one with a surface using a little roughness (0,00001). The results look like this: DF23_polished.jpg DF23_little_roughness.jpg Why d...

Hello all, This is the test condition: A light emitting surface with edge length of 1mm x 1mm emits 1 lm of light in an lambertian way. This is observed by a camera very far away (infinte) normal to the light surface. Theory says: luminance = luminous flux / solid angle / projected lit up area lumin...

Hi, If one coniders scientists and engineers, you have to have a clear idea what features you would offer them (and advertise as such). I really have a clear idea... I'd like to have a photometric real world visualisation, using physics based light sources that interacts with physics based surfaces ...

Hello, Rolls Royce I don't think that the parameters are to complicated. They in some cases just different. If you really like to remodel real world behaviour you'd probably need even more parameters. The question is where does luxcore want to go to? Does it like to be a cycles clone, or does it lik...

Hello all, I totally appreciate the discussion about spectral renderings. I agree to all of your pros and cons... my latest thread could point to one more situation that seems to be limited to current RGB solution. https://forums.luxcorerender.org/viewtopic.php?f=4&t=2678 I would like to see a &...

Hi CodeHD,

Does the solution of FarbigeWelt solve your issue? Does it meet your expectations?

Hello all, I'd like to create a special material combination. It is a special red acrylic that allows also a special yellow light to come through it and still looking yellow. The following image shows the absorption of the red acrylic and the spectrum of the light source. Material_VS_Emssion.jpg Is ...

Hello,

does this setup behave like you'd desired it? BR

Ideally with some optional interpolation types (e.g. linear, exponential etc) between those points.

Hi,

Might be the right time to introduce kind of brdf node that allows to define the portion of scattering types (matte, glossy, specular) per incidence angle. Ideally with some optional interpolation types (e.g. linear, exponential etc) between those points.

What do you think?
