The amount of light passing through the bsdf file

Hello friends
About the bsdf file. How do I know how much light is passing through this material(transmittance light)? Can I change the amount of this transmittance?
Thanks (32.7 KB)

Hi @Aliarch,

You can use BSDFViewer or the web-based viewer to see the light scattering of each patch of the incident hemisphere.

It is possible to change the scattering data manually in the xml file, however, I don’t think that is advisable. You’re are better off generating a new file.


thank you @mikkel
this is a file for scattering light.
Is there a bsdf file for focusing light?
