   Lights
  Is there a limit on how many lights that you can use at once?  I thought I heard something about 8 but my book didnt say anything about a limit.  And what would be the best way to produce a muzzle flash?  Thanks   -Rob 
  How many lights you can use depends on your graphics card.  Most modern cards allow you to have up to 8 *active* lights.  You can have pretty much how ever many total lights you want.  But there is a limit as to how many lights you can have active at any one particular time.As far as a muzzle flash goes, the easiest thing to do is to use a billboard.  This topic has been discussed many times here on GamDev, and there are plenty of resources on the net that talk about it as well.  Your book probably has a section on it too.  A simple Google search should give you all the info you need.neneboricua ;  Some games use a separate mesh, textured with a flash-looking map or something, that is rendered for the muzzle flash.  It''s a very simple and easy solution.  Plus, you can control exactly how you want it to look. ;  Yeah thats not a bad idea considering every gun will have a little differnt flash.  And about the lights, I see that like indoor levels have lights in the ceiling that look like there emmiting light but it might just be a lightmap with a nice bright texture.  Does anyone know of any good level creators(indoors)?  Because I am useing this one Called Cshop and it sucks.  I want one that I can make like walls and primatives ans texture them but me abe to import models that I made myself.    -Rob ;  qeradiant is a good level editor, but i don''t know about importing your own models.
