This is my first post, because the marketplace has not accept plugins or tools at present, I have to post here.
This mesh optimize tool is a standalone application, you may import FBX, DAE, OBJ, DXF and 3DS files, and export FBX files, generate high quality LOD levels with very low triangles count, it can also optimize huge 3d models while remain all animation/rigs.
This tool support both Windows(XP/7/8/10) and OS X(10.8/10.9/10.10) platform.
Yes it can be a handy program, but to take full advantage of it the engine needs to be able to recognize the _LOD0, _LOD1, etc naming convention on the object import.
Maybe next update I’m hoping.
