I made a low poly terrain world thing in Blender. I saved it and Imported it into Unity, but when I put in the FPS controller. It kept falling right through it. MInd I am new to Unity so this could be real obvious. If you know the answer to fixing this please tell me.
- Add Mesh Collider and select convex to ground.
- if doesnt work make sure your character is not kinematic.
Check the Gravity box
did you click the generate collider in your terrain?
I experienced a problem like this before. For some reason, Unity would not update the newly edited parts of my terrain to have a collider unless I saved the project first. I would give that a try. I would also try what anchampala said as well. Also, make sure that your character is both Kinematic and has some sort of collider attached.
