I am currently studying Procedural Shading using some tutorials from the Blender.org website. And I want to understand Eevee better. So a small project is a way to get some insights. As a subject, I choose the “Space Tourism” weekly Blender collab. Try it out also. Participating is easy, just add a reply with your render to that channel.
