Hey, thanks for replying
I basically; sculpted in 3dcoat - did an autotopo - baked sculpt onto retopo with auto uv. Then used the 'send to modo'. Normals are off, (can see the seams), I tried to invert the green, still weird.
Note- it does work to export the normal map separately from 3dcoat and bring that into modo. But it would be nice if the link one worked for me
I had fiddled a bit with the normal map settings, which didn't seem to work. (same problem with the default and tweaked normal prefs)
