Hey guys. I have a question. In some recent coasters, I have seen squares made out of brown lines in the editor. In the sim, they turn up as solid walls:
go to the auto-supports panel,
uncheck the 'wide supports' and 'handrails', but leave 'catwalks' checked,
uncheck the 'enable supports'
set building mode or something to final and make the supports,
you now have catwalks around your track. You can move the nodes and make your walls
