Author Topic: "Pixelated" Normal map  (Read 956 times)

Hi, Im having a problem, my normal map looks pixelated in UE4. Im using Substance Painter to bake (DirectX and Compute tangent space per fragment is checked), and the smoothing groups from UV shells.
Normal map file is a PNG 16bits.
Is a very simple object , the top surface is flat.

Is this a real problem? Maybe the dxt5 compression? Anyone can help me to solve this? :-\

Yes, it is most likely due to the DXT5 compression. Note that once compressed to DXT5, your normal map is not 16bpc any more, and in fact even less than 8bpc.

for this kind of object just use vertex normals, a normal map is not needed
