Ok, managed to close the gaps in the way I described (and left those holes for the light cones .. see 'new_front_panel.png')
Also made new exhausts in the way it can be seen on the real rearview pics, closer to the middle and cranked downwards ('new_exhaust_pipes.png')
Since it no longer has an internal Police light (which would disappear because of alpha channel transparency method
) I also tinted the windows again more and detached the side windows as :OT part so they can be hidden in menu, very useful for the few smokers that are still left ..
see attached pics of current state, I also added the car for testing (car_test.zip) without internal sounds .. fce meshload: 549kB, polyload: 3199
I will see what I can do about the layered taillights still, that's a reasonable objection Paul always had raised, if the bumper normals don't get messed up I will try to 'countersink' them into the rear bumper as a merged part so let's see what will become of it ..
