Perhaps you should have first tried to walk through cubes WITHOUT the noclip material and see what happens. Now go answer your question and feel amazed. :)

ok i'm wrong, or maybe i posted in the wrong way the question.

(i'm focused on using noclip on the floor : when the noclip is present the player pass trhough the materials. without noclip the player bounce a little.)
that's the point : in a lot of maps i found the noclip user on the floor surface to cover a lot of non-plain surfaces. that make me feel like i'm skating on ice, not running

I know that's subjective but I think is more realistic if the player bounce passing on some obstacles so i'm just trying to understand if there are some tecnical reason or not..

On Cube 2, you can use a geometry glitch to make the players skate on "ice". The real floor is noclipped, so you "hit" the geometry glitch and slip.

OK SIMPLE:

NO-CLIP:
This is used in maps to stop clipping on random object. In most games this is used much less, but hence the quake style game play (fast pace killing spree) it would be quite annoying if you clipped on things such as doorways and random things hanging from the ceiling. For the for no clip is normally added for aiming. It would suck **** if ran over sum hump in the floor and you dipped down 3 inches and you happen to be shooting at the time. So most humps and ditches are covered over for playability reasons. If this were a slower pace game, such as halo, l4d, tf2, etc. then we would use less clip and no-clip. So the point of clip and no-clip are more or less to solve playability problems, which are made by the artistic nature of the map.

that's the point. I guess the use may be related to gameplay. all i need was a confirmation.

perfect answer.

useful solution.

thankyou all.
