Chimney doesn't protect fire from rain even if covered and even has a roof?

[Unleashed]

As you can see in this screenshot, the thing is fully protected and has a roof, but when it rains it always goes out...
Any Idea why and how to fix it?

My guess would be perhaps a misalignment on the roof. It looks like smoke is escaping elsewhere. Can you plop some torches inside and get screenshots from inside looking up at a couple different angles?

my covered straight chimneys protect against the rain

You specifically need a thatch roof above the fire. a flat wooden platform does nothing. the rain degradation just passes through it

[Tachyon]

That's not really protected on either side. You need a vertical chimney with one of those little 1x1 ridged roof sections right on top. Floor sections let water through... because they don't count as roofs.

It looks like you're using flooring as a roof, which doesn't work. If your fire is below that, it won't be sheltered.

you cant use floor to protect your fireplace, the roof needs to sit above the fire. it will rain through the floor pieces on your fire

yep put roof on top of the chimney any you are good.

It looks like you used flat floors above the fire. There needs to be roof tiles directly above the fire, it's one of the quirks of the build system.

Something I noticed. Perhaps it's simply the design. The physics in this game are MUCH better than a lot of games. Smoke naturally wants to rise. trying to angle it out a side ventilation system like that, I'd imagine the smoke is amassing at the top and rolling out too slowly causing a buildup and is choking out your fire.

Try building it straight up like a regular chimney. Add 4 small support beams to the top, then add a roof on to of that. The smoke rises up and out the sides from a more natural angle. IMO of course. GL! Hope you figure it out!

Unless you put the flooring on first for maximum coverage, then throw thatch roofing over that. Did it to one of my structures. Works great.

as long as somewhere along the vertical axis there is a thatch roof above the fire* no need to be directly above, probably could of specified a bit better xD.

Really difficult to say from the screenshot.

You don't really need a chimney per se. I've had "open air" fire pits with only an exit hole properly placed several "layers" directly above.

You do need adequate air flow as I found out. Ex, if you place a fire and surround it by walls to make a chimney, leave an opening at top with a thatch roof covering, but constrict the air flow by putting a half block in the "chimney opening" you will get smoke inside and eventually the fire goes out.

It's also possible to slightly misplace your roofing/walls/whatever and leave a gap since the building is flexible. Redo (thatch, floor does not count as roof) roof over fire to check that.

Yeah, I love the smoke physics. I spend way too much time designing visually appealing chimneys and found smoke cannot pass through areas too restrictive. Beams seem to be able to block if too close together, even if it seems open enough. Notably a 1m x 2m beamed rectangle.

I should get some screenshots sometime. Another one I like is having a roof divider wall between sleep and fire area, then letting the roof peak funnel it outside. Our primary smelting port has the hut with that. Looks pretty neat.

You need a horizontal exit for the smoke since a lot of water will come straight down.

Oh it might be this then, I'll try and let you know ;)
