A consistency error is when a model (most often encountered in player models (p_model)) is preventing from launching the game.However the problem can be solved by typing MP_CONSISTENCY 0 before launching a game server in CS.However you may not be able to use the player model with errors in online/lan servers simply because 99.99% of the server's consistency is set at 1 when it's suppose to be 0.Then you can enter the server and not before that.
1. I dont know how to fix the muzzleflash problem
2. I did made a player model in the past but I never submitted because it didnt fitted nicely ingame plus it had consistency errors which is pretty annoying.
To WORK OUT means a session of physical exercise for training or to keep fit not working as a soldier,builder and such.And I wasn't working out all day long.Just 2 hours which is enough even too much.1 is enough but still.
