Thanks for the input Tinkerer. I was afraid of that. I'm trying to port items to the GM mode pallette so sadly these things need their own bounding boxes. Ah well I am making due and will just provide helper blockers to GMs also I suppose.
In regards to Cylinder AI bounds - I have applied this to several trees and pillars (via copy / paste and manually adjust the radius and height) and they all appear to work as expected (i.e. the AI refuses to walk through them and will "circle" them) so I don't think your assessment that they don't work is at least partially incorrect. At least as far as placed objects via GM mode. I dunno if Divinity Engine struggles with them during AI grid placement, patrols or the like. Shrug.
Anyway thanks all the same.
