My FPS just falls through the terrain?

My FPS just falls through the terrain now?

I dont know what I did but when I pres play the FPS just falls through terrain but it is placed above terrain?

WHat setting do I look at to stop this?

I assume you’re using the char controller package, which means character controller + character motor.

Check if your terrain have a collider. Make sure its layer and your character layer can collide in the Physics pannel (Edit->ProjectSettings->Physic). The last I can think of, your scale is way too small like .001 which means your character is falling too fast to register the collision.
