Hi. I need to turn off decorations culling completely so they will never disappear while they behind the wall. Disable Culling doesn't helps. Can you tell me please how to disable it, so even tall decorations will not disappear behind the default wall?

Sorry, there was a bug with the 'disable culling' option.
It should work as expected in 1.10.4

Still same. To recreate this problem, make a simple maze using default wall tiles. Now add a veeery tall decoration (like 80x1200) set it's scale to 4, Disable Culling, and play the game. When you'll walk through the maze always watch that tall decoration. It will disappear from time to time when you're too close to the wall that's between you and the decoration. I need an option to allow the decoration to be always drawn even if it's behind the wall

When I'm away from the wall it works:

But when I'll get closer to the wall it disappears:

Unfortunately it's still a problem. Clark is aware of this so let's hope for a possible fix.
