Thok barrier textures

As the zone builder tutorial says, I haven't chose any upper texture for the thok barrier, therefore where the texture is missing I should see the sky. However, while in 3D mode it shows the missing texture and in game I see graphical bugs. The thok barrier is composed by multiple adjacent sectors with different heights but I noticed that this thing in GFZ doesn't cause any problem. What else could I try?

Are both the floor and the ceiling of your Thok barrier at the same height? That's required for it to work properly

Yes they are, all values are <=0 if this matters

EDIT: I'm enclosing a picture:


The wall on the left shouldn't act like that.

What's the ceiling flat for the part of the thok barrier with the missing upper textures? It should be F_SKY1 if you want the sky to be visible.

I understood that F_SKY1 was only for the internal sector, now I solved, thank you!
