The model looks different than in Blender (weird shadows).

Do I need to filp the green channel for Normal map from 3DS Max into Blender or are they handling it the same way ? And to add to the confusing, what about Unity and Unreal? - #5 by iceythe - Basics & Interface - Blender Artists Community

Thanks, but I already found a solution. I just made a new normal map in Photoshop. It works well, in the picture on the left you can see the result, and in the picture on the right what it was before.
