It will attempt to plant the bricks in the order they were collected. I can think of a way to allow this but it would probably really lag for big builds. I'll look into it.
I would have assumed that it worked just like the duplicator's dupesave feature in that aspect. I think a very low build distance in your prop prefs can fix this from becoming a huge issue with items that shouldn't be on the ceiling. I think if you do implement this, there should be a preference to disable and enable it.
You have to be creative with this mod in order to get things to work the way you want them to. If you want a prop that specifically goes on the ceiling, you need to make sure that there is a brick, maybe invisible, that gets close enough to the player that they can plant it on the ceiling without hitting a very low prop build distance that may be set in place to keep other objects, such as crates, from being built on the ceiling.
There is a built-in too-far build distance that you can adjust with RTB prefs. I can probably modify the mod to allow a toggle between TDM and building modes that dont respect and respect build trust, respectively. I should fix item and emitter rotation first though.
Yeah, that's what I was saying, that there are restrictions keeping players from doing ridiculous things with this.
Like I said before, I know this mod is more focused on building destructible, prebuilt objects, but the creative applications for this is many and I was wondering if it would be possible to turn damage off, or make specific bricks immune to damage? I love the idea of basically being able to pick and purchase dupe saves, just not always for combat situations.
