Normal map in blender #63

How to decode the normal map in blender test set? I tried the traditional 2*rgb-1 but it doesn't look good, and the norm is not 1.

We never ended up using the normal maps and I believe they are faulty. They are the result of saving the "normal" render pass from blender. The method does not properly retain the complete information. I will remove them when I have the chance to avoid future confusion.

Thank you! I am trying to let the model learn the normal vector so I wanted to use those maps for evaluation. Need to find other datasets then.
