I fall down from my terrain !!

Hi there! I don`t know if I have any wrong parameter.I made a terrain and add a First Person Controler,some lights, and when I execute the program, I drop down to the level…every thing is correct, but when I approach to the valleys or cliffs, I fall down and down. :frowning: …any idea?

cheer!

Does the terrain have a collider?

yes it does !, and I added a first person controler as well.I made a mess myself adding and deleting, now I got it working, and I don´t know what was wrong. Thanks any way for your answer.

cheers.
