3D box disappearing. gif inside.

So I can't figure out what is going on here. Does the engine stop rendering the box when it thinks it's out of vision?

Well. I figured it was the x2 zoom events I had in there that messed up the 3D box object draw distances, I deleted that and it worked. I removed the link to the cap as I continued working on it.

Yeah, I think this is pretty much just the cut-off of the 3D camera. I also think you can change the view distance (in the game properties) to look from further away, and then make the boxes bigger, and that might fix it

Thanks for the reply.

Unfortunately that didn't help with the disappearing. Raising the eye distance (3d) just diminishes the 3d box effect. In fact, I'd like to lower it from the default 500.

Edit: Okay I just found out that raising the depth of the 3d box to the same or higher value as the 3D eye distance stops the disappearing. But this isn't ideal as the walls will obviously appear as skyscrapers. Anything else that might help fix this?
