###Scaling Artifacts
###Offset and Scaling Artifacts
When using a single texture for all the tiles, scaling the tileset (or even moving to a non pixel-aligned location) will most likely result in filtering artifacts like this:

This can't be avoided, as it is the way the hardware bilinear filter works. So, to avoid this situation, there are a few workarounds:
This can't be avoided, as it is the way the hardware bilinear filter works. So, to avoid this situation, there are a few workarounds, try the ones that look better for you:
* Use a single image for each tile, this will remove all artifacts but can be more cumbersome to implement, so first try the options below first.
* Disable filtering for either the tileset texture or the entire image loader (see the [Image Files](image_files) asset pipeline tutorial).
* Use a single image for each tile.
* Enable pixel snap (Set: ΅Scene -> Project Settings -> rasterizer/uxe_pixel_snap" to true).
* Viewport Scaling can often help shrinking the map (see the [Viewports](tutorial_viewports) tutorial).
