Edge split to make flat edge not working I've been struggling with this one for a day now. 





I will have to tackle why all of a sudden everything I put in game is extremely pixelated as well. However the issue I have here is the strange "x" shaped shadow that seams to lead into the handles at the centre. That is directly mirroring the triangulated mesh. In the past with weird artifacts like this usually marking the edge around it sharp and doing edge split modifier works but it is not working here. You can see the cyan lines where I tried to mark sharp edges usually this sort of thing would solve it. I have no idea what alternatives there are to flatten the plane of each drawer. Is it a normals thing? Do I need to fix those in some way too? I'd like to find something else besides Edge Split since it piles onto the mesh making it bigger in size.

Thanks in advance.

The X shaped shadow in your shader might be due to the triangles leading to the inner circle, you could try deleting those triangles and recreating using quads instead:
