Cracked Moon

How would one go about replicating the image below in Blender?

I’m interested mainly in learning how to create the model’s geometry and how to map to such an uneven object. I guess there’s no easy way to take a sphere and break it in half is there?

I have the moon map here:

I’m fairly new to Blender so any help would be appreciated. Thanks!

Yes there is…

Add a sphere, then go in edit mode and use the boundary selection tool (just press B on your keyboard and with the left mouse button pressed drag your mouse to form a rectangular area containing the vertices you want to select… If you press the ‘B’ button twice you get a cirular boundary…). Use the tool to select half of the sphere’s vertices and then press ‘P’ and from the “separate” menu choose ‘selected’…

Those vertices are now separated from the initial sphere…

You can use your imagination on how many fragments you want to “break” your sphere to…

In order for the trick to work nicely you will have to UV map the texture on the sphere… If you do this, the “fragments” will still carry the UV mapping information, even after you separate them from the initial Mesh…

Take a look on Modron’s UVMapping tutorial just a few posts bellow…

There are a few more good tutorials on UVMapping if you search the tutorials list…

I hope this helps…

Thanks for the help. I’ll do as you suggested. If I have more questions, I’ll be sure to post them here.

Thanks again!

Is that the moon from the
Tundarr the Barbarian Cartoon?
Sweet!

There is a python script by eeshlo called blast that will do just that, and animate it too,…I am pretty sure it only runs on earlier versions though. If anyone knows which Blender this script runs on, I’d be interested to know.

I’d rather use booleans to get a more ‘cracked’ look

Just happened to look here by accident… that script is not by me, but by strubi, and it is quite old, somewhere from the 1.80 days I think… You might be confusing it with dynamica which had a similar function. Anyway, not much use in modelling something like this at all I think, it just completely fragments the mesh.

If you want the moon to seem to be more than paper-thin, perhaps you can Extrude it in edit-mode. That is to make two concentric spheres. Of course you’ll need to slice through each one.

When you think you’re done, switch the view to Solid mode (from Wireframe) using the button at the bottom of the window, and look very carefully for missing faces. You can add these by selecting three or four co-planar points and pressing FKEY.
