So I am currently make a game in unity and I am using modular level design. I have created the modules in 3DS max using grid snapping so that everything is exactly 2x2 units. When I bring it into unity, they grid snap together perfectly. Here’s the problem, where the edges meet there is a tiny seam. If you get extremely close you can notice there is no microscopic gap or overlap between the two faces. The worst part is that it flickers, even if you’re standing still. Not only does it flicker, but it also happens to be a purplish flickering line between two greyish textures making it impossible to ignore. More information about the seam: Its one pixel thick, it only appears when you facing more perpendicular to the edge, if you are parallel with it, then it disappears. I’m guessing It has something to do with Unity’s estimating and rounding problems but I’m not sure and that doesn’t help me fix the problem. Hopefully one of you unity wizards can help me. Thank you 
Eureka! I found the answer! All you have to do is uncheck allow MSAA in the camera settings and the annoying little flickering lines dissapear! Hope this helps for anyone else that encounters this problem. Cheers
Is this really the recomended solution?
Cool if it helps but it looks more like a bug for me
