  Spin Velocity control with Slider being weird

  Posted by Tyler Lynn on December 18, 2020 at 6:40 pm

  I have a slider controlling the z rotation of an object with the expression

  time * .2*[thisComp.layer(“spin speed”).effect(“Slider Control”)(“Slider”)]

  When held on a single value, for example keeping the slider on 100, it works fine. But when speeding up /down the spin speed with the slider everything goes crazy! I assume it’s because the expression is calculating random values, instead of in a steady progression. How can I fix this? Thank you!
