Unless you recode maps and interiors entirely this is dumb. They where pretty stufftily programmed and screamed late 90s. You couldn't even have HD textures on terrain.
Use staticmaps mod if you want "interiors" that are actually massive-ass vehicle shapes and are a giant "forget you" to what vehicle shapes where intended for. That being said, it works. Someone aught to make something to automatically generate an invisible block structure for the collision of it too, because the collision on them sucks.
Do you really think Badspot wants to program a new terrain and interior system on his 10 year old game on a dead game engine? I think we've gotten a lot out of blockland for $20. It's still really good as it is, and staticmaps and old v20 installers exist.
