- MODEL TESTING
-
-The viewthing and gun positioning tools from Q2 have been integrated and
-enhanced into a single model testing facility.
-
-Model viewing can begin with either "testmodel <modelname>" or "testgun <modelname>".
-
-The names must be the full pathname after the basedir, like
-"models/weapons/v_launch/tris.md3" or "players/male/tris.md3"
-
-Testmodel will create a fake entity 100 units in front of the current view
-position, directly facing the viewer. It will remain immobile, so you can
-move around it to view it from different angles.
-
-Testgun will cause the model to follow the player around and supress the real
-view weapon model. The default frame 0 of most guns is completely off screen,
-so you will probably have to cycle a couple frames to see it.
-
-"nextframe", "prevframe", "nextskin", and "prevskin" commands will change the
-frame or skin of the testmodel. These are bound to F5, F6, F7, and F8 in
-q3default.cfg.
-
-If a gun is being tested, the "gun_x", "gun_y", and "gun_z" variables will let
-you adjust the positioning.
-
-Note that none of the model testing features update while the game is paused, so
-it may be convenient to test with deathmatch set to 1 so that bringing down the
-console doesn't pause the game.
