Title: Tilemap "Tearing"
Post by: brutang on January 04, 2015, 11:01:45 pm

I'm getting this issue on some tilemaps, mainly backgrounds, etc. I set the padding on the tilemap collection everywhere from default all the way up to 10. Anything I'm missing?

Image attached to demonstrate what I mean; i get a 1px line horizontally and vertically through the tile connections as my character is moving.

Thank you

Set sprite collection padding to 1, set to extend. That should improve it somewhat.

The appears when the geometry isn't aligned to a pixel, and either 1. the vertex gets transformed to the adjacent pixel, or 2. the uv sampling is incorrect. In the case of the latter the above should fix it.

same issue. I also went in and selected every tile individually and did extra padding: 1 - no different.

Are you displaying this tilemap pixel perfect on screen? Are you using an ortho camera / tk2dCamera?
If you're still having the issue then its probably not pixel perfect or aligned properly to a pixel, in which case you'll need to snap your camera position to pixel boundaries.

If you're still stuck, post a repro in the private support forum and I'll take a look.

Regular ortho camera (not tk2d camera although i switched to that and have the same issue).

Not sure what you mean by displaying it pixel perfect, sorry. Thanks for the help so far!

EDIT: Fixed it by changing Pixels Per Meter to 99.9 on Sprite Collection settings.
