By scaling the object, you mean scaling the transform of the gameObject I guess? If that's the case, it doesn't affect the mesh data in any way. The mesh is used for rendering on the same GO, but the data in the mesh is the same - it's not scaled.
If you want to calculate a volume of a mesh attached to a specific gameObject, you will need to do it on the gameObject level - calculate the volume of the mesh, then multiply it by the lossy scale of the transform the renderer is attached to. And by that I mean multiplying the volume (which is a scalar) by every element of the scale vector.Thu, 25 Aug 2016 13:21:05 GMTPangamini
