Zmapper - Obj' space Normal map 2 Blender

ZBrush Usage Questions
#1

Can anyone out there help me with ZMapper settings for a good
object space normal map export to Blender?

I’m using an object space map to avoid seam issues with the Tangent map.

But I’ve tried just aboiut every combination of ZMapper settings, and still
haven’t got a good render.

My best effort was ‘inverted’ in the sense that the illum’ in blender is
on the ‘back’ face of the object. But inverting the normal map in blender
just resulted in a totally un-illuminated surface (all black).

Hellpppp!

To work object space maps in blender you have to swap green and blue channel(blue channel need also to be inverted).
After you have to map to nor negative.
If you use the best object space maya configuration and after do this stuff it should work.

Thanks a lot renderdemon!

That does indeed do the trick (once I’d worked out how to get Gimp to
run the swaps for me).

Owe you one.
