This relates to the normals .exrs and mayyyybe the displacement map .pngs.
Convert them and then re-add them to Blender.

Update:

  • Photoshop can do this via Image -> Mode -> 8 Bits/Channel
  • GIMP can do this as well via Image -> Precision -> 8 bit integer

Time to test whether this fixes the normals. Don't forget to generate tangents:

Update: normal maps work when using 32 bit instead of 16 bit precision!
Displacement maps should be able to be implemented via a vertex shader: #171
