Fran...I think any old br whatever*[ even just a terrain saved as your scene's name...but somewhere else so you don't over write your work]* under the 10 M limit will do...just name it the same as your scene...we won't be looking at them or comparing and that box will not appear again...LOL.. ...

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
