It doesn't matter if I put the 2nd tilemap on another layer or not. Or whether they touch each other --though the idea is one is superimposed over the other --like a "layer" in RPG maker which allows you to have a tilemap for the floor and another on top of it for the walls and objects...
No matter what, If I create a 2nd tilemap object, the tile editor refers to the 2nd one only. I can simply no longer edit the tiles of the first tilemap object. AND no matter what, I'm editing the 2nd tilemap object.
Either there is a way and I just haven't figured it out or
Construct is limited to only one tilemap object or
this needs to be fixed.
I would really like to be able to have a tilemap that just has shadows and lighting effects that I can paint on top of my first tilemap. Or if collision is involved, have a tilemap for the floor where colision is ignored, and have another for the walls and objects.
