I cant find an option from tutorial 5

Hello folks, i can´t find the “import settings” in the right-click list when i loaded my terrain, i followed the tutorial :

http://unity3d.com/support/documentation/video/5.html

At the moment when he says “We can easily fix it with the imports settings”, i followed the same process but no import settings found in the tab… what to do?, that import settings serves to make object collide.

Note, i´m not using maya, just blender.

thank you in advance.

hm, not sure if he uses different version or something like that, but i made it by another way, in component physics set sphere collider and works…
