The dev wiki does not explain it well, and I cannot find the differences between them

The invisible texture is exactly what it sounds like, an invisible texture. It shares the same respects as a typical material texture you just can't see it. Including cutting up VIS leaves and being usable on entities.

The red CLIP texture is designed to block NPC and Player movement, as well as being invisible of course. Even though it stops NPC's and players, it will allow bullets, objects and other junk to pass through it. It also does not cut up VIS leaves or geometry. On a brush, if you use anything but the CLIP texture it wont work.

Like hanging_rope said, if you want to block only NPC's or Players, use the individual CLIP textures.

I am assuming you you are talking about the red "CLIP" texture and the normal (only) INVISIBLE texture.

Dosnt explain properly. Why not use nodraw instead of invisible?

Invisible wrote:
Solid to all objects, invisible and does not cast shadows.

Nodraw wrote:
Solid; Invisible; seals leaks; blocks visibility if used on all surfaces of the same brush. Casts shadows.

Can you use Nodraw for a Portal Bumper?

Yes, but don't. Try putting a nodraw brush in the middle of a map and tell me what happens.
