Hello guys,
I have a strange problem with Softimage’s realtime display in viewport.
There is a cube with a normal map generated from highpoly smoothed cube.
When I apply realtime shader and setup the maps - the weird black line appears where it should be nice normalmapped edge.
I did a test described here (comparing the same object with the same normal maps in different application viewports):

Why the same object with the same normalmap looks good in 3ds max viewport and bad in Softimage’s viewport? As you can see normalmap file is not the case as 3ds max displays both good - the one generated by softimage and the one generated from 3ds max itself.
Could you possibly know what I did wrong or what is the case here?

Cheers,
Idaho
