Forcing an autotile?

[Asterion]

Hi, all; I've been using RPGM for about a week now, and was hoping to get some input on something that's been vexing me from the start.

A feature that I've wanted to have in my map is a stream of water flowing out from the base of a building. Unfortunately, the autotiling system has been sort of... interfering with that:



Instead of flowing out from beneath the bricks, the water can only just stop short. I tried adding overlay tiles of holes for the water to be moving through, and they look great with the water, but all of the natural-looking ones betray that they're covering grass instead of brick.

So, might there be a way to force the top square of the river look like it's continuing past the edge of the building? I imagine I could do a lot of mucking around with setting the autotiled versions as their own tiles, but I'd rather avoid that, if at all possible. Thank you!

What you want is a small part of the so-called "shift-click-mapping".


As a new user, I suggest you follow the link to the "starting point" in my signature, it contains explanations and links to other tutorials (including shift-click-mapping) and is probably the fastest way to get the basics of RM.

Oh, this is perfect. Thank you!
