?support non vertex anim frames
test failed model loading
?is PicoFixSurfaceNormals needed?
shaderlab_terrain.ase great error spam
shaderlab_terrain.ase great error spam, table2.ase
split to smaller meshes
aiProcess_SplitLargeMeshes is inefficient
handle nodes transformations; or aiProcess_PreTransformVertices -> applies them (but also removes animations)
