Possible to change tilesource collision image?

i got runtime loading of the image displayed on a tilemap, but i’m wondering if it is possible to change the image used for collision during runtime aswell.

No, that is not possible. I would recommend that you look into resource properties and possibly Live Update to achieve this kind of thing.

I am trying to make a modding API, so i want to cut down on baked-in things when possible.
This isn’t the biggest loss, though, since i can just reserve a partition of the tiles to be used with collisions.
