//generatetangents 	bool 	Generate tangent space using miktspace, useful if mesh has a normal map that was also baked using miktspace (such as blender or xnormal) 	false
//subdivscheme 	string 	Subdivision algorithm, options are "loop" and "microdisplacement" 	"loop"
//displacementmap 	string 	Name of the texture used for the displacement. Subdivscheme parameter must always be provided, as load-time displacement is handled by the loop-subdivision code. 	none - optional. (loop subdiv can be used without displacement, microdisplacement will not affect the mesh without a displacement map specified)
//dmscale 	float 	Scale of the displacement (for an LDR map, this is the maximum height of the displacement in meter) 	0.1
//dmoffset 	float 	Offset of the displacement. 	0
//dmnormalsmooth 	bool 	Smoothing of the normals of the subdivided faces. Only valid for loop subdivision. 	true
//dmnormalsplit 	bool 	Force the mesh to split along breaks in the normal. If a mesh has no normals (flat-shaded) it will rip open on all edges. Only valid for loop subdivision. 	false
//dmsharpboundary 	bool 	Try to preserve mesh boundaries during subdivision. Only valid for loop subdivision. 	false
//nsubdivlevels 	integer 	Number of subdivision levels. This is only recursive for loop subdivision, microdisplacement will need much larger values (such as 50). 	0
