Cryptomatte - C4DtoA setting

[cdordelly09]

Hi! What is the correct method to add the cryptomattte AOVs with C4DtoA? I tried to use it with the provided script in the user guide but I get some issues to read it in fusion.

I get this error:

...agic Design\Fusion\Modules\Lua\cryptomatte_utilities.lua:323: attempt to index a nil value

stack traceback:

...agic Design\Fusion\Modules\Lua\cryptomatte_utilities.lua:323: in function 'parse_manifest'

...\Roaming\Blackmagic Design\Fusion\Fuses\cryptomatte.fuse:425: in function <...\Roaming\Blackmagic Design\Fusion\Fuses\cryptomatte.fuse:413>

Cryptomatte1 failed at time 0

Maybe I need to change something in the Crypto Driver?

The Cryptomatte node works fine in fusion because I already tested with the Cryptomatte sample images so I'm thinking that my issue are in C4D.

The scene are attached. Thanks!

Your scene looks good to me, the EXR loads fine in Nuke. I have no Fusion, so I can not test it there, but this is the output from my render:

Hi @Peter Horvath! Your file works perfect in fusion, maybe I'm doing something wrong in C4D, I'll try to reinstall the cryptomatte and re-render the file.

I already reinstall the Cryptomatte and works perfect, thanks Peter!

Im having the same problem, how did you do you install for c4d? I followed the guide in the C4Dtoa Doc but no luck

Hi @Frederick Ross, I only re downloaded the cryptomatte shader from the AL site and reinstalled just like the instructions. Be sure that you are downloading the build for your OS.
