Blender terrains and gravity

Questions & Answers
1

I made my terrain in blender as I wanted more direct control over the topology and appearance of the terrain. I also thought that I would save on verts by doing this as I used a lot of flat terrain in my game so I really don’t need a deformable mesh for that.

I have two questions:

  1. is it true that I am saving memory by making a terrain in blender?
  2. I am having trouble with gravity. I attached a mesh collider and it doesn’t work most of the time. A terrain collider doesn’t work at all. Can we only use unity terrain if we want to have objects with gravity?

You need to use a mesh collider. I had this same problem when I imported an object from Maya and found it out. It should work with blender objects, too. I also think you need to use a Gravity script. You can put a RigidBody on it and enable gravity. For the textures you should’ve separate objects and drag the materials to those objects. And yes, you saved memory and a lot a frame rate.
