'growing' spiral stair problem


i’ve been trying to animate a growing shape by adapting the spiral stair tutorial here:


but i’m starting to think i may be on the wrong track.

the dupliframes option does just what i need, except i need the staircase to grow in the animation, and not be constantly built in every frame.

can i adapt this method or do i need to adopt a different method to automatically duplicate objects in time?

thanks for any suggestions,


Dupli Frames is a modeling tool - not animation tool.
Can you describe how exactly you want the stair to “grow”, because there are different ways of “growing” :slight_smile:
