Fast64 is a Blender plugin for creating levels and other 3D objects for the Super Mario 64 decompilation project. This page is a collection of common issues you may encounter when working with Fast64.

Error message: 'NoneType' object has no attribute 'draw_layer_1_cycle_1'

If you created a new scene from scratch, it might be missing a world. Ensure you set a world (new or existing) in the scene, since Fast64 stores some settings in the Blender world object.
