I have checked torque indicators code - I am not sure how exactly you expected it can work, draw_havoc_engine_bar uses 2D draw functions that no longer longer work with the 3D cockpit. You can't just copy old code, it should be modified for sub objects manipulation, or texture animation. I have changed trq_gauge object and added function to control it's scale->y value, that's the way how usual instruments works. You just need to set in the scene parent's position, and object rotation (to fit cockpit surface), other indicators can be added same way. And, are you sure you have used exactly the same function as in the 1.15.0? as this particular bar behave differently.
