when i try to import it says blender is not found but i have it all saved in 1 fial
At the moment Unity can import only from Blender 2.49. If you're using it then make sure it's associated with Blender files.
I am using Blender 2.49 with Unity and it works great! All you have to do is have your *.blend file located in the Assets folder of your Unity project, and Unity imports the contents of the blend file automatically every time you make a change in Blender and save.
