One of the most requested Godot tutorials I get is to cover how to export models from Blender to Godot and retain textures, animations and more. Therefore I have created exactly that tutorial in both video and text formats, hosted on our sister site devga.me. This tutorial is mostly in Blender, showing how to properly configure textures, an armature and create NLA strips so when exported “it just works” in Godot. This example uses Blender 2.79 and Godot 3.1.
Don’t forget, if you want to learn Godot we have a complete Godot 3.x tutorial series available here, a step by step creating a full 2D game tutorial available here. We also have Blender tutorials available in our tutorial section that should get you up to speed using the popular open source 3D application.
