how to make a sample cube with 1000 vertices ?

i am a beginner . because do a test of Collision, i need one sample cube with 1000 vertices.

how to do? more detail is better,thanks.

For collision you don’t really need a cube like that. Doesn’t really make a difference whether it has 8 or 1000 vertices since you should use a primitive box collider anyways.

Using a 3d modelling program

Why ?

You should use the standard BoxCollider component since it will always outperform a MeshCollider component. Upon collision the Collision object should provide sufficient information about where the collision occurred (see contacts).
