I think it is ironic how most of the work of making static shapes is put into making the collision meshes, rather than the visuals.
Like seriously, someone find a way to auto-write collision meshes or something.
I feel bad for the people trying to make maps, they spend hours making the loving collision meshes for them.
I'm not a programmer but it would be nice if someone would program something to autowrite the collision meshes.
Maybe than I would get blender and make a blockland static map. if I made one it would be one of a full house: a map with bedrooms, kitchen,
living room, hallway, backyard, frontyard, and maybe something extra, all in one building.
If it takes this long to make collision for one room, HELL NO am I going to make a full house map!
But this addon is great and I'm grateful that there are people willing to sit at their computers for hours to make the collision for maps that already exist! just to be able to play them on v21.
keep working on this, eventually you'll find and easy solution to this time consuming problem.
