Compositing: Image -> Value conversion is incompatible with older compositor
Closed, ResolvedPublic


In old compositor, connection from color output to scalar number input simply converts RGB to brightness, however afer tile branch merge it seems to convert to brightness*alpha so the results of post processing will be much different from older ones.

I don't know if this change is intended, but it should irritate us because we have to modify the node settings in most of all older .blend files.

I just posted the patch for this problem:

Please check it.

Has the compositor's behavior been accidentally changed? Or, should I modify my existing .blend files???
