I'm having issues with my 2d tilemap. When the camera moves, I see gaps or tears on the tilemap. I have found a couple of solutions that work some of the time: One is to set a negative cell gap on the tile grid. The other is to make use of another sprite material with pixel snap checked. With the negative cell gap, I still occasionally see issues when the camera moves. Pixel snap is inconsistent, it seems to work perfectly for awhile, then the problem returns. Does anyone know why this is happening? And if there is a better solution to the problem?
