A friend of mine is handing me multi-pass EXR renders from octane and I'm looking to rebuild and composite them in Nuke. I'm not familiar with the way passes from Octane rebuild to re-create the beauty. Given that Octane renders out filters for each pass, I'm guessing it isn't additive, such as Arnold. Can anyone tell me the correct order and operations needed to rebuild a beauty pass out of Octane for C4D or Houdini. Any help would be appreciated.
