		const float	fw[4],
		struct LinkNode **	poly_nodes )

Find the final derived mesh tessface for a particle, from its original tessface index. This is slow and can be optimized but only for many lookups.

Parameters

mesh_final	Final mesh, it may not have the same topology as original mesh.
mesh_original	Original mesh, use for accessing poly to MFace mapping.
findex_orig	The input tessface index.
fw	Face weights (position of the particle inside the findex_orig tessface).
poly_nodes	May be NULL, otherwise an array of linked list, one for each final mesh_final face, containing all its tessfaces indices.

Returns

The mesh_final tessface index.
