Rigging and control help needed
I am new to rigging and controls, and would appreciate some guidance on creating a single control so that animators can use a simple translation control to extend a mechanical umbrella.
The geometry is part of a larger component, the components to be included in the rig is a telescopic pipe comprising of two parts an inner and an outer with the inner pipe attached (parented) to a head, four flaps are connected (parented) to the head.
Basically I want one control so that when the head is pulled upwards the entire thing will extend, at the halfway point the four flaps should start to rotate outwards and be horizontal by the time the head is fully extended. I managed to get the telescopic pipe to work by using two locators and point constraints, with one locator parented to the head, but I have no clue how to make the flaps rotate.
I have attached some sequence images to better explain what I mean.
The first image is the rig stowed, the second is at about the halfway point when the flaps should start to move and the third image is the rig fully extended.
Thanks for any help.
