pimp, I worked it out.
There's an extra line in the default .lua that wasn't in my custom sceneVR file. It must go in when you go to Open Beta. My custom hangars are all made for the non-open beta version.
Weird though that in the open beta, non MT version, they work fine.
The line I needed to add is: sceneAPI:setEnvironmentMap("Bazar/Graphics/VRMainScene.dds",0.9);
Thanks for reading my post - I'll mark off as "solved now".
Solved this but left the post in case it helps somebody else.
Using R+Ctrl and Enter, I brought up the controller window. Found out that after updating DCS and also "calibrating" my Thrustmaster TFlight rudder pedals, the wheel brakes are always a little bit on! See the attached pics. With the help of Sacarino in a post below, I adjusted some settings in the rudder toe brake control mapping and all's well 🙂
Moral is: Use the Control Overlay to troubleshoot.
Original post as follows:
Since updating to DCS Open Beta 2.7.11.21408, all my hogs, A-10A, A-10C and A-10C II won't spool engines up to take off speed.
Taking off is impossible, even without any payload and half a tank of fuel.
When applying wheel brakes at the start of a take off, the bird doesn't even pull through them.
I've checked my wheel brakes haven't somehow become inverted, have ensured airbrakes are retracted and it happens whether skid or no-skid.
At Kobuleti, taking off Eastward in zero wind, by the time I get to the last hangar on the right, I'm just starting to get airborne.
At Groom Lake, Nevada, I don't even get speed for take off before running out of runway doing 115kts - again, no wind, no payload, flaps at 10 as always.
I've mapped keys to throttle and the throttle handles go all the way to the front stop, whether with the keys or my Thrustmaster Warthog HOTAS.
I've tried my other aircraft; AH-64 (torque easily goes above 100%), F/A-18C (still gets off the ground nice and quickly).
All ok on the Thrustmaster Calibration panel.
Have tried other missions; my own and the DCS Quick Start take off missions too (never played these before, was nice to hear Waggs).
The hogs all behaved perfectly before the update.
Has anybody else had this issue?
