I just tried out for the first time the driveable Jeep (with and without .50) included in my B.A.T. 4.0 game. At spawning the thing does a rollover crash and the game is over. An error says hook Engine1ES_01 is not found. I tried adding such a hook, but to no avail. The new error is
INTERNAL ERROR: HierMesh: Wrong chunk idx (-1, N:19). I note that my newly added hook in CF_D0.msh is 19th (and last) in the list.
I looked at the model in the mesh viewer. What a mess! For starters, the nice tires are floating in the air. Not of importance, of course, is the presence of other aircraft meshes and hooks that weren't removed/cleaned up what making this new 'aircraft'.
Anyhoo, where can I find a working version? I wanted to test out behaviour with my new treatment of the layered forest. If the driveable vehicles are treated as aircraft, I would need to add an exception (or other code if I want to create certain consequences) for these if we don't want them to be stopped/damaged/destroyed when abutting a forest edge.
