Volume absorption definition
Hi all, From measurements I know the exact transmission of some different coloured clear materials. Due to having this measurement with different thicknesses I'm able to calculate the absorption coefficient. In old luxrender it was possible to transfer this absorption coefficient to the render engin...

Re: Angular roughness/Angular glossiness
Hi,
But if you select a static color instead of IOR the angular dependency is lost, isn't it?

Re: Angular roughness/Angular glossiness
Hi all, I think the "glossy" material node has an option called "IOR". If one select this the amount of reflection is calculated by Fresnel law. The Fresnel law makes a reflection more bright with more plain observation angle. Additionally the roughness parameter could be used to...

Re: parallax mapping Fstorm
Hi,
Thank you very much.

From now on you're my personal hero. A test scene runs much quicker than before and reaches the good result in a time that I could get little animations with a single weekend of rendering.
Thank you very much.

Re: parallax mapping Fstorm
Hi, with complicated light paths I meant something like that: Lichtleiter_neu.jpg I've added the blend-file to that post. If you'd like you could try to find a solution to reach this result without biDir. It would be really helpful for me to find something to speed those kind of visualisations up. T...

Re: parallax mapping Fstorm
Hello,
BiDir is still the only engine that seems to be able to manage complicated light paths...
I guess is often used by people that care about the physics based realism.Bidir isn't often used so it is not a lost

Re: export IES file from Luzrender
Hi,
I would be interested in such a tool as well.
Could you please be a little more specific how you might get some [cd] values from luxcorerender?

Reducing roughness by value
Hello all,
what happens if I reduce the roughness value (limit with direct entry is 0,001) with the help of an value node? Is it possible to reach lower roughness values with this trick?
Thank you.
