Hi
I wonder if its just me, but I tried the exposure slider on the Physical Lens, and it seams to do nothing, the intensity slider works
Tried 19.0.546 and 19.0.531, same behaviour
Cheers

And, there seams that the Lens Shader only works on LOP Cameras, imported one from OBJ and added the properties under Karma Lens Properties , but the "karma:camera:lensshader" is not being set correctly
Cheers

Those both seem like bugs, the latter being a bug in Scene Import.

Would you mind logging an issue for each of those, with a simple hip file if possible?

Thanks!
