This is going to be short. I think there should be a way to open up the Garage Doors at the Auto Service Station for that extra imagination, especially for those who like to customize their cars in the right area. I told ya it was short, but, I think this idea would be a big hit!
I love this idea, I love it when maps are interactable in a way but how would this work? would they open up if you got close?
Well GTA does this with some of the house gates, boom gates, and garage doors where if you get close they open up, but this might require the garage door or the entire garage to be it's own prop on the map (logically, anyway, I don't really know though)
The way Sandy Mountain did it was with animated meshes, which are much lighter on performance and probably easier to develop than anything JBeam-based. And the code used to make them work is pretty standardized, iirc, so it shouldn't become outdated, break, or need much upkeep. The only cost is that they don't have collision, so should you drive into one before it raises off the ground, you'll just phase right through it.
