Asking if anyone else has had this problem before. I know it's a simple fix, but have been scratching my head for couple days now.
I made a simple/custom "sliding door" for a "cabin/room"
(it is part of a custom segment). Note the wall next to the door
with the "door" closed. With the "door" open the wall is
transparent!
With Door Closed

With Door Open

At first I thought it might be the shader I applied, but
removed it and same problem?
Any help would be great

thanks, best
My games never have bugs. They just develop random features..
