I’m trying to use a tilemap collider 2d in conjunction with a composite collider 2d to have “walls” on the edges of the tiles but the composite collider doesn’t seem to be merging them properly in some places and as a result i get walls where i don’t want them.
the red arrows indicate where it’s generating walls where i don’t want them.
i did some tests and apparently it works fine with a normal tile.
It breaks when using a terrain tile from the 2d extras, any way to fix it?
Edit: i tried using the rule tile instead and it seems to break on the edges of rotated tiles?
a year later and this is still broken, no idea how to fix it.
Just ran into this 
pretty annoying. Do you know if it still happens when using a rule tile made from scratch? (versus duplicating the example one?)
Never managed to fix this, and i haven’t tried since the last time i posted. You could try making your own rule tile from scratch or try to figure out what’s doing it in the existing one, i moved on to other projects since then but id appreciate it if you could share your solution if you figure it out!
For sure - I’ll tinker some more and post again if I happen to find the fix. Pretty annoying 
Thanks for the reply! 
Did anyone find a fix for this? Having exactly the same issue. Manual tiles are fine but rule tiles are causing all sorts of weird additional bits.
I ended up moving on to other stuff 
couldnt get it working properly ><
There is a new option in the CompositeCollider2D in Unity 2019.1.3f1, Offset Distance, along with the existing Vertex distance to help deal with the gaps.
If anyone encounters this thread- I don’t think its supposed to fix this, but this probably shouldnt happen in the first place so i guess whatever works ^^
I really dont know if it’ll work for you but for me it worked to simply hover with a regular tile from the palette over the painted ones in the scene
And yes, I laughed so hard when I found out this was the fix for it.
