Discovered this tool a few days ago and I really enjoy using it. I would like to present a suggestion to help fix bleeding/flickering issues. Due to the way texture rendering works, using the objects created by this tool with regular sprite sheets will often result in bleeding problems in an engine.

Here's an example of what I mean:

Now, the same website also links to a common fix:

The workaround is using an extra 1px border around the tiles. I myself use a gimp script to generate these (http://registry.gimp.org/node/24816 for anyone interested). Unfortunately, using extra spacing dealigns the grid. It would be nice to have an extra option under Extra UV Grid Settings for spacing to accommodate this.

Thanks for creating this tool! It's great to work with.

Thanks for letting me know about this, I did not know this. My use case would have been with unfiltered and non mip mapped textures so I wouldn't have come across it otherwise.

I noticed this issue as well both when rendering and using BDX. Bleed border would be much appreciated! :)

So I can get a handle on this problem, I'd like to know what your workflows are for adding the bleed border to your textures.

Ample's Gimp link is the way I work around the issue generally: 1 or 2 extra pixels surrounding each tile. In the created gutter the outermost line of pixels immediately neighboring the border are duplicated. That's pretty much it. :)

Hey folks. Just wanted to let the thread know that tile padding will be in the next release!

To access tile padding, select a tile grid and expand the Extra UV Grid Settings options.
