Hi guys I've updated to 2.2.1 and now always getting strange result in my emission aov. The mesh lights are surrounded by noisy specular highlights and I have no idea where it's coming from as I don't have any emission on this meshes. Also there is no problem when I preview the channel aov in ipr, this problem only appears when I render to tiff/exr. Any ideas?!
You have specular highlights in the emission AOV? I can't repro that, can you post a simple example scene or ass file?
I have some weird thing that looks like spec highlights in emission channel, but I have no idea what's that.
I was digging in the problem and found out that it's a transmission channel in standart_surface is causing the trouble. The transmission is catching the light from a nearby sources and transferring it to emission channel! Damn, have no idea whats that, seem like a bug.
Seems to be a bug, indeed, we're looking into it.
Weirdly if you create a custom AOV with the light path expression C[LO], that seems to work.
