I’m new to the hex casting mod. I recently found it while making a modpack and immediately fell in love with its magic system (mainly because it’s somewhat similar to my own magic system in my fantasy world).

I’ve watched like one or two tutorials but mostly been exploring the mod by myself (maybe with the occasional Google search). I’ve seen a few creations of others and was wondering if it was possible to create a function to define an area instead of making a list with all the positions (like a simple sphere for example {(X-g)^2 + (Y-h)^2 + (Z-j)^2 = r^2})

Are there any ways to make something like this in base hex casting or are there any addons that help with such?
