about the VRML exporter, when you play ,just enable it from the video plugin config and it will export it each 10/15 frames (i think), to stop it, just deselect it (needed to make the file readable). the file will be exported in the main emulator folder (e.g. "C:/Project64/") with the name of the rom with *.vrml extention.To open it, just use "import" fonction in 3d studio max or another.
icepir: IMPORTANT: each time something is exported, the triangles are all flipped on the wrong side! Can you fix that? (not doing it on the nemu plugin)
