collision shapes create extra unwanted collision bounds when they are placed with a small gap.

example, as you can see the collisions have an extra collision boundry that goes up unto the sand.

here is what the collision bounds i defined look like, and there are not multiple collision layers. the collision is normal when placed using a normal tilemaplayer.

these are animated tiles by the way

i was doing more messing around and this happened as well

I can't reproduce the issue on my end... Could you share more details on exactly how this was set up? Like if you have multiple Terrains in the same atlas? I think maybe the tile you're using to paint the World Grid might have hitboxes, which appears in-game on top of the ones in the Display Grid.

Unfortunately I don't have much time to work on this nowadays, but it could help the next time someone views this issue.

I'm using the 4.4 latest main branch commit and set up a tileset with 1 physics layer and got this result when i played the scene with Visible Collision Shapes:

The collision hitboxes appear normal to me, though I might be missing something.

I am using godot 4.5, which may be the problem. Sorry if this information is not what you needed but I've never done a github issue before sorry. If there's a way to show the backend grid in a way that shows would help debug then i can do that.

Here is my tileset with all the collisions.

Here's what my tileset looks like, with the terrain drawn onto it.

I only have the collision drawn onto the water tiles. The water tiles are animated. I went around an inspected my shoreline and it seems to be mainly caused by when the terrain is near a curve, as straight lines are normal. ill share some examples of those below.
I did try making the sand bounds of the terrain set bigger but it made it worse.

I ended up swapping back to how it looked before, and it made those issues stop but readded the previosly mention issues. Here are some examples of what it looks like with the terrain drawn like the photo of it at the start.

Straight lines are fine but the areas near turns of the sand seem to cause all the issues.

Also, i had a partially unrelated question. Is tilemapdual compatible with big tiles?

I had this dock asset i made, but it won't place on the tilemapdual layer, and neither will anything that isn't a part of a terrain set. I have to make a normal tilemaplayer for it, and that causes the tilemapdual water collisions to block walking on the dock and i was wondering if there was a way to make it work on the tilemapdual layer.

Thanks for your responese!
