Terrain Isn't Hidden When Converting to Railing Walls

[sutcac]

I know I have run into this before but never really zeroed in on what the issue is. Trying to do an open carport as in the second image. I start out with solid walls and the terrain hides like it should, but convert to railings and the terrain is not longer hidden. Why? No change to the room definition. I know I can do a terrain hole, but it just shouldn't work this way. Am I missing something?

How about a terrain feature, the size of the carport, and set the elevation to whatever you need

[sutcac]

Terrain features don't influence the terrain. You don't set an elevation for them. Are you talking about an elevation region? I think the terrain hole actually works better because it doesn't influence the terrain. I am just curious why the change to railings negates the hidden terrain. Maybe it's just a bug. It just gets annoying because with each movement of these exterior walls, I keep having to go back and re-size the terrain hole.

Yes, your right, I use a lot of terrain elevation regions to get what I need in most cases. I guess the terrain hole is your best bet.

Yes, I use a lot of them too. And, I think I am finally figuring out Terrain Breaks!
