Ok, Still got problems.
Although now I see the new naming sequence in FRED, it does not list ALL of nebs in the effects folder, it runs out at F9, thus making the rest of the F's, G's, H's and I's not rendered.
For example, I put a copy of your "Hell's Inferno" into a mission via text editing, loaded it in FRED, and althought the background editor listed the proper names (G-series) of placed nebs, the selection list didnt. Alas there were no background nebs showing in FRED. So I thought maybe the Game will still render them, but no, it didn't.
Is FRED limited to how many nebs it can display in the background editor?
Why doesnt the game render types that FRED doesnt list when the file names are correct and the files are in their respective folder?
ie. If I use one of your other releases such as "Sinister Creation" where it uses the "A" group primarily, they show up in-game and in-FRED.
FRED version I'm using is 'fred2_open_r_08282005'
Sorry for all the questioning, just trying to wrap my head around whats happening.
