This should add a recipe to convert your regular chimneys to always smoking ones. Add a stack of 32 charcoal below your crafted chimney block in the crafting grid to light it up, then place like normal.
You can also "extinguish" the smoking chimney by placing it into the block grid, which will return the original vanilla version.

This first version is only able to convert 4 chimney types as it uses the vanilla creative mode chimney pieces, which are legacy blocks. This currently only includes the red, gray (blue), brown, and tan (fire) chimneys. As a result of the smoking versions being legacy blocks, the colors are a bit off when compared to the original survival mode chimneys.

I'll work on converting the current 7 versions of survival mode chimneys to have a lit version with smoking stacks in a future release. This should fix the colors as well.

I was very quickly able to figure out how to make it work with with all 7 variants of the survival block chimneys. However, any previously placed blocks from the 1.0.0 release will still have the old variants. Unfortunately, you will need to re-create the chimneys again in order to see the new variants. Nope, that should work too. "Extinguishing" the old lit variants to return the vanilla survival version, which you can re-light to the new variant if desired.

Designed for VS 1.20.3, should work with any 1.20.x

Confirmed to work for dedicated servers.
