Hi, I have planes (faces back to back) that are getting ### ERROR couldn't build bsp because of overlapping surfaces (orange). This was taking from the a10 bsp so it shouldn't be erroring, so I assume I'm doing the shader tag wrong. "alpha_test#" this happened to some glass too that had the '#' material tag and i just deleted it. I also have a z buffered triangle that I can't find.

I saw where the video had the same error as me, but it's very compressed and hard to understand. I honestly couldn't get anything from this video.

Thanks. I figured that, but if bungie's original model had 2 sided and transparency there must have been some flag for both of those. I'll do that thanks.
