FPS actions in a whole-world sim will be problematic. FPS engines provide the telescopic detail levels, but a world engine would need special rendering exceptions for what you describe, Zeos. Could it be done? Heck, anything seems possible these days. But in terms of more global thinking, is that a feature that would be a high priority? Sure would add to the immersion when the product is much further along on its timeline. I love the ideas that come along in this forum. Sure wish I had the code skills to at least offer some sort of help. Massive project!!
