imported terrain does not work with terrain collider, only mesh collider

Unity Engine
1

So I have been using the terrain from unity up until now, but want to have more editing ability so made the terrain in Blender and imported it to unity. All seemed well, but when trying to play the game the character falls through. I have tried the following:

add a box collider, does not help
add a terrain collider, does not help
add a mesh collider, works partially as the character object is going through some places, but at least he does not fall through.

Just to check that there was nothing wrong with my character i created a terrain from within unity and the character stayed on it withouth falling through. I tried adding a rigid body to the character and also a box and both fell through with the imported terrain, but they stayed/landed correctly on the terrain from Unity.

Anyone have any tips on what might be wrong? Strange that it works 80%ish with a mesh collider, but falls through every time with all other colliders.

You wouldn’t be able to use a box collider with a terrain, because it’s not shaped like a box. A terrain collider can only work with a Unity terrain, since it needs a TerrainData object.

aaaaaaah… so I MUST use a mesh collider then. Thanks for clarifying that. Think i found the collison problem also. Thanks for the reply.
