I'm testing this shader and have a problem with noise. There is no specular effects in scene. I've tried different materials (Arch, Mila, Mia Advanced, legacy) and hdri images, high sample values but ugly noise is still there.
My setup: create area light, turn on visible, select shape as user, connect user_ibl_env with hdri and set samples along with light samples. Am I missing something?
no spec, yep, thats the BIG problem. their is actually no consistence workflow with mr's ibl and shaders in general and spec/reflect workflow because nothing is connected because of the outdated mr integration.
you would need a native implementation of booth, mila and ibl (also for mia, but let us stop to talk about mia because its heavily outdated) and of course different visibility options that follows the new lpe paradigm.
