Error Messages Rosetta Stone
BCE0048: Type 'UnityEngine.Transform' does not support slicing.
Meaning: You didn't declare an array properly. For instance:
var t : Transform = new Transform; is wrong;
var t : Transform = new Transform; is right.
Actor::updateMassFromShapes: Compute mesh inertia tensor failed for one of the actor's mesh shapes! Please change mesh geometry or supply a tensor manually!
You probably have a mesh collider and rigidbody attached to a plane. The physics engine is unable to calculate the object's mass, and is giving the error message. Removing the mesh collider or rigidbody from the plane should fix the issue. (SK)
Internal Unity Errors
In a perfect world, you'd never see these errors. In the real world, UT can't possibly test every single combination of scripts, objects, components, etc. (I mean, if they could, they'd have created every game!) So, once in a while, one of these slips through. They're typically harmless, if annoying. UT more than likely would appreciate you filing a bug report with your project attached.
