I was importing a few textures and what I observed was some were being imported at a high res while others were being imported at very low res. Looks like a bug. Suddenly by chance all of them reverted to good quality yesterday, and today I face the same problem. Happens with only a few.

Hmmm… In the editor go to the toolbar, settings, and engine scalability settings and change that. Otherwise, I know that in maya there is a setting to see a mesh being smoothed without actually applying the smoothing to it — this might be your problem.

Texture imported is of low quality
