@Odin: in the meinit file you need to set su-39 humancockpit=yes.
Then in the "Bazar\World\Shapes" folder, you need to copy and rename those 2 files:
kabina-su-25t.cmd rename to kabina-su-39.cmd
kabina-su-25t-glass.lom rename to kabina-su-39-glass.lom
You're done. The Su-25TM (Su-39) will share the same FM, cockpit (etc...) than the Su-25T.
I also have some great news:
Thanks to Skypat's ModMan 6, there is no need to edit your graphics.cfg file, it is all automated now. My package will automatically edit the trees value to "trees = {200000, 15000}" as requested by TekaTeka's Tree Shader Mod installation. It will also add the requested path to the new cdds files included in this package (no need to use the cfgupdate util anymore), will edit the fogparam2 value to "0" to remove building transparency and also modifies the "around_object" value to 15000. Finally, it will edit the noise values as suggested by rockwelder with his Ground Pounder Terrain. I've tested this extensively this weekend and it works like a charm :thumbup:
What it means:
No graphics.cfg replacement = no need to redo your game settings, they will stay the same after installation, and the mod installation will edit only the required lines, and revert them back to default values on uninstallation :)
Can't thank Skypat enough for that!
Cheers,
