I have a cube and a normal map that makes the edges look rounded. If I use any kind of filtering for the normal map sampler I see really thin seams, I know what's causing it but don't know what to do about it. If I use no (or point) filtering the seems goes away but then it's pixelated when I get up close. What should i do ? Is this a common problem ?
PS - I'm using D3D9 and HLSL
