This course is designed to help you get started with blender addon development. It takes you through the basics of python all the way to ray casting in 3D space. There are many explanations for each step along the way. The course includes the addon downloads for each step of the way. If you have any questions or get stuck feel free to ask and I will assist you the best I can!
