Hi,
I have spent some time trying to resolve this problem but I keep getting more and more confused. I stumbled upon this issue when converting and exporting normal maps for a game.
The basic problem I have can be reproduced like this:
- Create a new scene
- Open the node view, enable nodes
- Create a Combine RGBA node and set R, G and B to 0.5. (Keep alpha at 1.)
- Connect the Combine RGBA node to either a file output or a Composite node.
What I would expect is to get an image that has RGB=(127,127,127) everywhere.
However, I do get an image with RGB=(188,188,188) - which confuses me greatly and makes all the normals in my normal map point towards an incorrect direction.
I guess blender is applying some sort of color conversion before displaying or saving the file but I have found no mention of this in the documentation. I am using Version 2.71-2 on Arch linux. Any help is greatly appreciated!
Thank you!
