CFS2 doesnt support rear canopy. But you can reassign the variable to concorde visor. Either by using MDLC to extract a source that you can edit and then recompiling it. Or by using a hex editor to directly change the mdl.
In the source code change this {9E5C1C92-D1A9-477F-B78C-68AD64D4AF56} r_canopy
for this {89E2CA9B-1E3C-4647-B1C2-50117EC99508} visor
In a hex editor Find these bytes
Code:
92 1C 5C 9E A9 D1 7F 47 B7 8C 68 AD 64 D4 AF 56
and replace with these
Code:
9B CA E2 89 3C 1E 47 46 B1 C2 50 11 7E C9 95 08
Model converters take note, how the byte order of those numbers appear changed when compiled in a model. Hex editing is much quicker than MDLC.
