Ok guys: BIG UPDATE:
I was able to export the Daimler successfully and brought it into the game!
But got a few problems though, like
1) I copied (with help of Wolfi) the tweaks for MainGun and the MG, MG has sounds, but if I fire the MainGun, I dont here the sound. The tweak is exactly the same like the Abrams, name changed to DaimlerMK1 ofcourse (except the path for sound). Anyone got Ideas?
2) My car is driving forwards all the time without doing anything.
Now some pictures:
View when "entered", Rotates with turret. (Needs more work, this is just temporary.)
And I'm proud that I could manage the wreck so that the turret as a wreck is in the same position as it was before!
Edit: Just fixed the height of the vehicle so now there is no longer so much space between the wheels and the body.
