Flickering while rendering from different perspectives
Hello Together, I have an issue, with rendering images of a static scene from different angles. If i Rotate the camera around a lighting element there is some kind of flickering on the floor (See gif). 0001-0156.gif The setup is very somple (and also attaced): There is some led which is lighting up ...

Re: Settings to get the luminance in an .exr file
Thanks for the fast reply.
Im using the Blender Plugin. ´The file im working with is attached. I've deactivated the tone mapping and set gamma to 1, view Transform to raw and exposure to 0.
Thanks

Settings to get the luminance in an .exr file
Hello Together, I heard that in an .exr-File the Luminance in cd/m^2 is stored. Here: https://forums.luxcorerender.org/viewtopic.php?f=4&t=1601&p=20519&hilit=.exr+luminance#p20519 is said, that if I turn off the Tonemapper the values are stored in cd/m^2. In my opinion this vaule shouldn...

Re: Gussian Scatter as surface property
Ah i see. Schicks Brdf alone has no scattering. Its just an alternative for Fresnel?
In the glossy Material is also a lambertian scattering implemented?

Re: Gussian Scatter as surface property
Yeah i mean a gaussian distrubution around the specular Reflection. The formula i have is similar: f(\rho)=C * exp^(\rho)^2/(2\sigma^2)] with \sigma=1/(sqrt(2ln(2)) * HWHM and \rho$is the angle between the normal and the scattered normal Anyone know how to implement this? Can i take the cpp and chan...

Gussian Scatter as surface property
Hello together,
Is there a material node that scatters like the Gaussian Scatter function. I know that glossy material works with the Schlick brdf. Is there a way to kompare the Schlick model with the Gaussian model?
If not is it hard to implement?
Thanks,
Meinhard
