I joined this forum pretty much when the ck came out, and then I took a break. I just recently started making a player home for the first time and was disappointed to find that in game, parts of the floor and walls kept vanishing until I was a few feet from them, where they would reappear again. I've seen outdoor objects vanish in the early release of the ck, but indoor objects disappearing? today? Anyone have this problem, or figure out a work around. It was kinda disappointing putting all that work into it, testing it, and finding this problem. Thanks.

If you duplicated the cell your using from a vanilla cell, then you also duplicated the room bounds. You need to remove them if your changing the layout of the cell.

toolbar >View >Show/Hide Window
check mark 'Portals and Rooms'.

Thanks for the response. Hmm I actually did remove the rooms and portals early on. Maybe I missed some? I'll check it out again.

Edit: Ah that led me to checking the occlusion plane box.. and I found several left over occlusion walls... thanks.
