I load up an area (Say an interior) in the CK, and in the render window only half the area shows. There are obviously other walls objects and such in the items list and when I double click one it zooms me to it.. only.... It's invisible.

I have had this issue before and I fixed it by editing something in the Ini file (I think) but I can not for the life of me remember what. But it basically makes the Creation kit load every single thing in that's listed in the object window. (Apparently the ini file is set up to only load partials, and not even let you load more then one master file without editing it I have already had to edit the damn thing about 4 times just to get it to allow me to make more complicated mods, its stupid and ridiculous and all of this [censored] should be enable on it by "Default").

If anyone knows how to set it to do load everything, please let me know.

Thanks

You can force CK to load everything in a cell by pressing F5. By default a lot of items will be automatically hidden in order to maintain acceptable performance. Someone else might know how to get around this permanently.

f5 does not work in this case. It happens with cells which have parts used by other cells.

did you check "unhide all on render window reload" (or stg like it) in render window preferences / misc...?
