#3DS Problem
I did a full reinstallation of 3DS.
I tried something else too; I loaded up one of my projects that was
not working correctly and hid everything. Then I unhid single
objects, one at a time and rendered each time. The first few objects
rendered fine (the carpet, floor tile, walls, ceiling and wood
paneling), then as I unhid more objects, I was told that it couldn't
find the texture maps I was using for the objects that were already
unhid and rendered OK.
I tried rendering the scenes with OUTPUT-RENDER-COORDS=OFF and it
still gave me messages that it couldn't find the maps, but I didn't
get the .LOC file error.
