Hello everyone, I made a disc with a pattern with the node editor, and the pattern shape can be controlled by adjusting the node parameters of the circular array, which is very good, but there is a small regret that when I save the node file and open it again, there will be an error, and I need to adjust the parameters of the idxselect node to display it correctly. I would like to share the file with you. I call this work Metachrystal
