I increase it while rotating the shape using Copy(SOP)<\/p>\n

For example. rotate by 60 degrees to increase to 6 pieces.<\/p>\n

Things like snowy crstals can be made quite easily.
\nThose kaleidoscope type things can not be judged because they make fun patterns even if made properly.
\nAlso, it’s interesting to change the pattern by moving parameters such as Angle.<\/p>\n
