Snap Points Problem

Development Modding ARK: Survival Evolved

I am in progress on a mod that requires snapping items to foundations. Currently, I am having some problems with strange obstruction. It’s late here and I’m tired, so maybe I just haven’t played with them enough, but here is what’s going on:

In the first, you can see that I have placed one object at the side of a foundation successfully. I put up a wall to test placement against a wall, and I get an obstruction message, which would seem normal if not for image 2, where I can place a wall behind the already placed object. And image 3 is just bizarre. It will successfully snap to intersecting both the currently existing object and the wall.

I currently have the objects snapping to match group 2 for the foundation snapping. I have the walls ignored for snapping and have adjusted my snap coordinates so that the meshes fit properly on the foundations.

Any suggestions?

Have you tried unchecking “Use Placement Collision Check” in the actor blueprint? That won’t help where the game code breaks and just says that you can’t place a structure in that location but it should stop the can’t place due to obstruction messages.

Thanks hogscraper. I still want it to obstruct, but only if it’s actually obstructed. I figured it out after two 10 hour days of staring at snap numbers and blueprints comparison.

For anyone that may find this helpful:
If you put the flag number of the thing you want to not be obstructing your structure in the “Trace Ignore Structures with Type Flags” box, it will ignore items with those flags when placing. I only found this out when I tracked down how foundations ignore the check for pillars.
