ok this is pissing me the Fehh… off now…
i have a hexagon, but i want to fill it with squares, without getting triangles… how do i do this? tried everything 
Well… you have a pentagon. You’re going to have to add a cut somewhere, you can’t get an even number of sides out of an odd number of sides.
Not to be nit-picky, but that’s a Pentagon, not a hexagon 
Interesting dilemma though, I’m having a go at it now…
[EDIT] Actually easy, just need to make an additional cut.
Ye. With 5 vertices it’s impossible to have it in quads without adding or removing an edge loop.
Top: starting point
From bottom left:
- Filling with a face and adding an edge loop
- This gives fourth vertex to fill with a quad
- But I don’t know what this is part of so migth be better order to have the face loops from left to go straight through. Merged selected vertices from the middle (alt+M) to get that.
ye ofc 
simple miss spelling 
anyway, thank you both, it soulved the problem.
however i have another question, how did you add the colors JA12? can i do that in cycles?
By assigning multiple materials like Modron hinted there. Should work with Cycles too, although you might need to use the viewport color option with it.
