Probable bug in (regular) Path tracing method
Closed, ResolvedPublic


System Information
Windows 7 - Geforce GTX760

Blender Version
Broken: 2.72 95182d1 (official 2.72)

Short description of error
Rendering with regular path tracing method (no branchedPT) and using a "sharp" glossy shader I get reflections in the diffuse passes, both direct and indirect. Can't think that is intended ;)

Exact steps for others to reproduce the error
Open the file render then switch to the other method and render in another slot. Then compare the passes output{F116492}

Hope the report is ok, bye!

Sergey Sharybin (sergey) lowered the priority of this task from Needs Triage by Developer to Normal.

Can confirm it here, but only when the glossy is being mixed/added with a diffuse shader. Without a diffuse shader, it works fine.
