This script produces optimized meshes from MagicaVoxel imported OBJ art.By analyzing and grouping the MeshFilter content, it produces vast polygon reductions averaging 50-90% of the source input polygons, depending on the model and amount of used colors.It then saves these optimized meshes as .asset-files for re-use.It may work with other imported voxel-like geometry, but it's specifically aimed at MagicaVoxel.[UPDATE 06.07.2015]MagicaVoxel v0.96.1 changed the way how OBJ geometry is exported. This breaks the PolyReduce process. Please use v0.96 when exporting to OBJ for now. The Asset will work on these OBJ files without problems.I am currently working on an algorithm update for the most recent version. This Update will then also introduce new Lightmapping features.
