Quake3World

Recently I saw something strange in one of my projects:
With r_showtris 1 I saw the outlines of one of the models inserted into one of my maps (the id major statue) outside the level bonds in the void. Still, the model was in the right place inside the map. Could that be because the origin accidentially lies somewhere in the void? Has even anyone ever seen that, too?

You probably accidentally made a copy of the model and placed the copy out in the void. IIRC, that normally that gives you an error. Anyway, you shouldn't have polygons rendered out in the void if you didn't specifically put something out there, or don't have any complicated sky portals or mirror portals, etc.

True, if its origin is OUTSIDE the map, it should not be visible. But you are maybe right monaster - because when the origin of model is inside of map than it is rendered even in void. I saw it in my map too.

Here's a screenshot that I've been able to take recently of that phenomenon:
You'll see the original model (default major statue) on the right, perfectly visible when playing without "r_showtris 1" by the way, and its "ghost version" on the very left being already in the void.
