Over the last few months I’ve been working on a planet generator for blender Cycles in my free time. I wanted to have 100% procedural materials and it should be as versatile as possible to allow me to create a large variety of planets. At the moment there are more than 100 settings across all group nodes, so I had to split it up into multiple group nodes for different planet properties like terrain, poles or cityscapes that can all be combined.
Here is an example planet from different perspectives:
And here is how the group node setup for this planet surface material looks like:
Here are a few more planet renders. The view of the whole planet on the left takes around 30 min to render and the view on the right around 1 hour (1920x1080 500 samples with an RTX 2070):
I also made shader groups for lava and moons:
Finally, I also made shader groups for gas planets, including planetary rings:
I still have a lot to do before I feel confident to release it. Most of the nodes inside the group nodes are still node spaghetti and I still have to go through some of the older node setups and update them with what I have learned since I started this project. Feedback is always appreciated.
