Normal Map Node Has Issues #202

Closed AlexeyAdamitsky closed 8 months ago

AlexeyAdamitsky commented 2 years ago

It isn't working as expected. The resulted shading feels inverted on all axis. I still can't figure out what exactly is happening wrong here but I strongly suspect there are issues which comes from Y-up vs Z-up coordinate systems difference in Arnold and Blender.

Order The one obvious thing we're missing right now is the Order dropdown menu. I believe the default order in Blender should be XZY.

Strength I'm not sure but I believe the hard minimum should be 0.

I've been testing Normal Map node. All my test point that in Blender we better set Color to Signed and Tangent Space to enabled by default. I don't know what Normalize does (or rather I fail to see any effect from this parameter) so I suggest we leave it disabled.
