How to avoid the rain dropping through the roof?

#1 Add portals
it will stop the rain for showing inside.. much like how it stops the terrain from showing..

#2 In TGE 1.5.2 I find the Show Terrain toggle doesn't actually work. I saw some other folks having this issue as well. They appear to be portalized because rain doesn't show through them and I receive a massive framerate boost when entering the building as it stops rendering occluded content. Any ideas?

#3 Thanks. But it doesn't work to me.

I still can see the rain dropping through the roof. Where should I add the portals?

#4 You need to make sure that the entire building is closed up. So if you have windows, doors, ect. You will need to portal them off. Also make sure theres no leaking holes in the corners and such. Any little leak will keep the portal system from working and then at that point your going to see rain inside the buildings.

#5 @ Thomas,

Thanks. Do you know how to make the triumphal arch portal off?
