Heres what mine look like:

but when I add something else and texture it, it looks fine, that is exactly what mine looks like too.

Open up your .BAK file for the .map you are creating they are
the same, BAK is just short for backup, see if the back up is
the same.

Hope this works, fingers crossed.....

how should I open it, should i rename it a map file? or...

Not using CoDRadiant go into your cod/main/maps folder you
will see your .BAK file thats associated with the .map file you made.

yourmapname.BAK

Right click it and open with, browse to the codradiant.exe

C:/ProgramFiles/Callofduty/tools/bin/CoDradiant.exe is default path.

See how that goes, im assuming of course you have not attempted
to save since you noticed these white textures.

when i do that codradiant opens, but no map loads

that is a memory leak log
is this for cod radiant or uo radiant?

i made the map with codradiant

would this not be easier to delete and remake those 2 blobk houses?

this happened to the whole map, it is pretty big, so no not really
