¿can i draw Objects only when in a certain range around the Player?
hi there :b
You'll see... I have a level were you're walking thru a LOOOOONG Avenue full of Zombies & other physic objects like boxes, cars & stuff... it is at night so the player can't se anything beyond certain zone around him & zombies won't follow you until you can see them.... Problem is, there's a lot of stuff being draw, even if it's not visible yet. I don't really have performance troubles yet but anyways i wanna know if there's a way to only draw stuff like enemies & other objects when you get close to them.
was thinking about changing the clipping range of the camera but it also stop drawing buildings so it looks ugly (maybe could i apply the clipping range only to certain objects?) *also a friend of mine suggested me creating triggers to spawn objects while you're going thru the level, but as far as i have seen, this creates an awful little lag. *then i though about making spawners that creates zombies one by one, before you get close, but once the object is there, it still there & even if i could erase them, if the player goes back, the level would be empty...
Any ideas?
maybe i'm overthinking it too much & i'm just a beginner but i really wanna make it as flow & fast as i can
thanks you very much O:!

One approach would be to place your buildings on one layer and set the culling mask of a camera to render only that layer, using a far clipping plane. Then place all your other in-game objects (zombies, boxes, cars and stuff) on another layer and use a second camera to render that layer with a much closer clipping plane.

for anyone coming to this answer, i did what Tanoshimi suggested me; i used a Camera to render just the buildings & Skybox, then i used another to render other objects & put this as a child of the other camera. Problem then was that then i could see those objects even if they were behind buildings, i solved this by creating a script that when coming near to a certain range & therefore rendered, those objects were moved into the default layer so it was normally rendered, then when out of sight, they come back to the other Layer.
