Use blender file as a Terrain?
Its exactly as it sounds i make a object using blender and when i put it in unity i put a character controller (both 3rd person and first person) and i raise then up so there defiantly not in the middle of the object and they fall right through.
I think the terrain is the world or the ground you can stand on correct me if im wrong.
Both the object and the character are centered to zero on all axis’s.
The blender object is a plane shaped using the sculpted tool, and is exported as a .blend file.
Please explain what im doing wrong as if your talking to a little kid i’m still new to this stuff
A mesh renderer just lets you see it, but you need to have a collider for anything to collide. By default, an imported mesh generates a mesh collider. The player need a collider too (capsule collider probably.)
You should also try adding a Rigidbody component to the ground (check it as Kinematic and lock the position) and in edit>project settings>physics make sure that the ground and the player objects are both on layers set to collide with each other.
Thanks I’m going to use that for a different level. I already used the Object2Terrian script on it and it worked but that sounds much easier.
