Having begun this thread and opened this bucket of worms, I sort of feel responsible for the problems. I haven't added to the thread because I do not wish to make work for anyone. You, Epervier, have done more for 409ers than anyone, and I certainly do not feel it right for me to ask any more than what you've already accomplished. I downloaded the Weapons_De folder and placed it in my my mods folder. I definitely think it helped with the cockpit flash problem. The issue seems to be with my Me-410, specifically the B model loadouts. With the weapons folder in place, I guess roughly half the loadouts give the following error message in QMB:
Mission loading failed: INTERNAL
ERROR: Effect param file
'effects/smokes/Gun.eff' NOT loaded
Without your weapons folder, I do not get this error message, however, the cockpit yellow flash returns.
I do not post this to ask for any more effort on the issue, but to merely try to provide info.
Thank you, to all, for your help!!!
