Sculpt in medium resolution of a praying mantis. Legs and arms are detachable, all made out of uv spheres. If you are using this file, please make sure to give the proper attribution. Cheers.
Strange... Are you using Blender 2.8. My apologies if it doesn't have very good backwards compatibility. I created this using Blender 2.8 (Beta at the moment). I think 2.79 is able open and edit it without problems.
Niice..Is that a Martian Mantis??
