To my knowledge the first set of model props ever released which contains Helicopters in model format based upon the Black Mesa Research Facility. The pack includes 6 animated model variations - 3 in regular size - 3 in miniature size for scripted_sequence usage.
I'd like to point out that I'm not the author of the models and as far as the transport helicopter goes it was originally created many years back by:
Model, Skin :-
Animations : PRiMACORD
I can't say who created the other helicopter model as I downloaded that one from a Russian site which acts more as some sort of storage site where they collect all sorts of models for mappers. Should the original author see this Helicopter and identify the model as his\hers please contact me so that I can add you to the credits. Additional Information can get gathered inside the readme.
The pack consists of:
-6 Black Mesa Helicopter models
-3 in regular size
-3 in miniature size
Each model has 3 Animations:
Rotor (Rotors are online. Same Animation name as for the Mini_Osprey.)
slow_spin (The Rotors are slower indicating that it's soon preparing to launch or just landed.)
This pack is on a free to use basis. I would love seeing this in many upcoming SP maps and mods for Hl1. :)
I hope you folks will have fun with it.
