Dear all,

We are using a Houdini Classic shader for transparent objects

It seems the Houdini physically based rendering engine does not support Transmittance color for transparent objects, is this correct or are we doing something wrong, is there a work around?



Thank you

Regards,
Cyrill

Check the box (Enable Absorption and Nested Dielectrics) on your mantra rop. Alternatively, don't use the pbr renderer. There's almost no reason to use pbr anymore, unless you are using your own custom pbr pathtracer, as the raytrace shader calls the pbr code producing identical results (there are a few exceptions, such as gathered emission for volumes.)
