Increased threshold for engine vibe at high speed/revs
Updated run-time creation of wheel collision shape and wheel render mesh setup, so the corresponding actor can be created at wheel offset instead of vehicle origin.
Added wheel shapes (updated according to wheel pose) to vehicle actor to detect wheel-to-wheel contacts.
Added wheel helper shapes to vehicle actor to retain basic collision response for wheels.
Forces and damage resulting from wheel-to-wheel contacts are applied to vehicle.
Added support for factor (specified in data) to adjust the amount of effects applied on wheel-to-wheel contacts.
FFB impact force more authoritative (requires new profile)
Disabled wheel helper shapes.
Threshold for wheel detach caused by damage is now used also for detach caused by wheel-to-wheel contacts.
Fixed intermittent loss of control response (e.g. cycle hud/info).
Restored wheel-to-wheel contacts between AI vehicles.
Added tweakers for wheel contacts
Enable dev pause in all configs
Fix default livery not showing up in menu at first for new profiles.
Game server protocol changes:
– Added support for alternative game server port received from the redirector. This will allow us to switch to Java-only server easily in the future
– The game will now request replies to be in the formatted text format. This argument is ignored by the PHP server as it does not support any other format, but will be required once we switch to the Java server
– Added handling of free trial login replies
