Game Developer Jeremy Burns has released a new free plug-in for Blender that allows you to add a playable 3D version of Mario into your scenes to run around and test your terrain layout. This plug-in is a part of Burns’ libsm64 library that provides a frontend to movement and rendering code generated by recent work to decompile the ROM for Nintendo’s 1996 3D platformer Super Mario 64.
With the add-on enabled there should be a LibSM64 tab in the properties sidebar. You need to browse to an unmodified SM64 US z64 ROM, and then click the "Insert Mario" button to insert a controllable Mario at the 3D cursor location. To stop the simulation just delete the "LibSM64 Mario" object from the scene.
