Cryptomatte problem

[marcovalmori6]

Hello,

I'm having some trouble with a cryptomatte pass; basically after setting up the driver (either by using the tool under Arnold/utilities/setep cryptomatte or by using a script), the final render has a bluish color cast, not present in the actual render, and by looking at the console, it gives me this warning:

Could you help me figure out what's going on? i've never had such a problem in the past, right now i'm on R25 with Arnold 4.0.0.1

Thanks

I cannot reproduce this with CINEMA 4D R25 and the latest C4toA, on Windows 10

Can you tell me how to reproduce the warning? Or upload an example scene?

And maybe an Arnold log (with verbosity = Info) ?
