This tools should be modifiers instead of tools that you open, apply and close:
- Array, it would be so much flexible to have it as a modifier instead of a window tool...
- Spacing Tool, same here
also,
compound objects should be modifiers for the same reason:
- Scatter
- Boolean
maybe this is the case for MCG, but included as a built-in modifier.
It's in the philosophy of Max to work with modifiers,
the stack is the most powerful tool in Max,
adding this would empower procedural content and motion graphics animations.
