yeah and I think the venture workshop runs pretty fast too! LOL!!!
But as to all this broo-ha-ha about fast running levels. There is a compromise you have to make. I am working on a "library" level. If I put all the bookshelves in it a normal library would have, NONE of the bots can find their way around efficiently. So I remove a few tables, widen a few corricors, throw out some bookshelves and things get better. What is the most complex and realistic in level building often translates into lousy runtimes and gameplay. What we forget as "artists" is that the objective is to engage an enemy, solve a puzzle, and navigate our way through a building; not build a "realistic" building.
By the way, I moved the origin up high on a model and made him taller. He now leaps over the tables to come get me.
