pior do you import your normalmap as a normalmap into unreal? i didn't try and maybe you did but if you didn't you should try it, as importing it as a ordinary texture always messes up things in unreal
They are already broken up in the uv's and i think that all the other sharp edges are looking ok. Will try and harden the edges along the seem. But I think that I've already tried this... Edit: Ok this helped, Thanks! Although I got some of those black seems in between.. However, how will this work with the smoothing…
