Does FaceIndex parametr in OnHit procedure work at all?

It’s told that it only works with trimeshes and landscape.Well, for me it always gave -1 except trimeshes and landscape, then it fed me 0.

Well, looks like it doesnt work 'cause OnHit works with collision models. It can potentially work if col-models are optimized for it, but i found RayCast for working with model geometry itself for my purposes.
