hi, i am runing into this problem using vray normal map.

the more i bump multiplier next to bump slot (in which i have vray normal map) the more the reflections rotate. not sure what am i doing wrong here.

attaching images showing the problem. 1st with mult. set to 100 and second set to 200. as you see the reflections rotate for some reason and there isnt difference in normal effect.

any idea?1.jpg

I think the normal map is doing exactly what it supposed to do.

You can try switching the RB orientation and see if it give you a better result.

Other problem could be that your normal map is not good or was not created correctly.

switching RB just makes the reflections rotate in opposite direction. looks like the normal map is pretty much useless in vray as only time the reflections stay correct is when mult. set to 0. i am using normal map online generator. never had problem with normal maps it produces in unreal engine. even trying normal map from different source produces the same effect.
