... OK guys, here is the B-25H-1 USA with its dedicated Textures folder (as there is no US standing gunner, I had to "cheat" a bit) ...
https://www.mediafire.com/file/vw54o2xhxi72zed/B-25H-1(USA).7z/fileCredits :
Pilots & gunners : Ranwers
B-25C pilots & gunners addition : gunner0134
"As usual" fixes : Epervier
Next step the "J" series ...
EDIT :
Sorry, I forgot to delete all lines related to Pilot3 (borrowed from gunny0134's C version, but not visible in H version)
Starts line 1212 of hier.him file for those using Notepad2 ...
So open the hier.him, scroll way down to [Pilot3_D0] and either put a double slash like illustrated, or delete all lines related to Pilot3, Hmask3 and Pilot3_D1 ...
