Animate Glass BSDF Index of Refraction over Time? Is there a way to animate the index of refraction of a glass material so that it will change from say 1.1 at frame 10 to 1.8 at frame 30?
Have you keyframed them? Go to frame 10 in the timeline, set the IOR to 1.1, right-click the IOR, click "insert keyframe." Go to frame 30, set the IOR to 1.8, and insert the keyframe again.
