Short description of error
Cryptomatte rendering works fine if 'Accurate Mode' is enabled and the Material Cryptomatte Pass is checked. As soon as 'Accurate Mode' it is disabled, Blender closes immediately when starting a rendering with F12. It is worth noting that I was not able to reproduce this every time. Sometimes I had to render twice or three times to have Blender Crash.
The output in the Console is:
Windows fatal exception: access violation Thread 0x0000395cWindows fatal exception: access violation Windows fatal exception: access violation Windows fatal exception: Error : EXCEPTION_ACCESS_VIOLATION access violationAddress : 0x00007FF697CE3EC4 Error : EXCEPTION_ACCESS_VIOLATION Windows fatal exception: Address : 0x00007FF697CE3EC4 Module : C:\blender-git\build_windows_Full_x64_vc15_Release\bin\Release\blender.exe access violation
Exact steps for others to reproduce the error
- Start Blender with Factory Settings
- Use Cycles as Render Engine
- In the Passes Tab, enable 'Material' Cryptomatte Pass
- In the same tab, uncheck 'Accurate Mode'
- Hit F12 -> Crash
