Matte shadow distortion

[miro.digital]

Hey guys,

recently had a project rendered out both as a single layer file and also with render channels + matte surface with shadows. Single layer file rendered perfect, but the matte's shadow alpha came out distorted. Any ideas what causes the issue?

CPU render on Windows, Houdini 17.5.391, nightly 5519.

Thanks!

Chris.

Hey there !

Are you by any chance using the Irradiance Map option under the GI settings ?

Cheers!

Hey Gosho,

nah, used BF/LC with CPU. Shall I try BF only?

Thanks!

No, no need for that. It was a long shot anyway. To be fair, I have no clue. Is it possible to share the scene so we can check for issues ?

Cheers!

Haha, okay! I have an NDA in place, will try to replace the objects in the scene and send you the link in email.

Thanks again!
