If you tried the default BR101 locomotive in game, there is an lcd display imitation in it's cab, and there is blue quad that raising and lowering as the current is changing. Now that's what i want to replicate, but i can't. i've modelled a quad, tried to animate it by scaling, or moving vertexes. In the modelling software it works, but not in game, where nothing happens. I tried reset xform, everything. Only the rotation, or position changing animations appear in game.
How did they do it on br101?
