Leak through cylinder=unfixable

[Emperor Jack]

I have a leak that goes through an inverted cylinder. It is going to be used as a pipe/slide thingy like in rotcannon. I have replaced it like you do with other brushes. No fix. I have created and oppostite invert to it (a pipe around the outside so it dosnt look invisble from the void. I have replaced it about 50 times. No fix. The red line goes right through the middle. It pisses me off really really bad.

Any help will be pleasured!

Patches aren't structural, you need to have caulked brushes forming a box around it.

Patches are detail, you need to have caulked brushes forming a box around it.

Whoops.
Typo fail.
Fixed now

Everything leaks through cylinders. Put normal brushes between them and the void.

Not only cylinders. All curves are not structural.

Anything that's a patch of some kind doesn't count as structural
