  • Controlling Triangle Points

    Hi

    I’ve created a triangle using corner pin (attaching TL point to TR to get rid of one side) as I want to control each of the three points individually. I’d like the points to slide away from the centre of the triangle randomly, so separated the x,y,z controls, attached y to x on each point and used a wiggle expression, however on the lower left point, I need the expression to make y move in the opposite value to x.

    Hope this makes sense, I’ve added a couple of pics…

    I think you just need to put a minus sign (-) in front of the expression that ties Y to X.
