Smoothly altering Time scale for Materials

Hi there,

I had a question about working with the Time node in the material editor. It seems that if I multiply the time node by a value to increase or decrease the time scale, everything acts accordingly. However, if I attempt to smoothly move that multiplier say between 1 and 2, the material seems to radically glitch out for each step in the transition. This makes sense to me, as I am assuming that since the time value is changing each frame, every step in the multiplier’s interpolation between the two points is quite different than the previous frame. Is there any way however to smoothly interpolate between two “speeds” in a material? In the attached image, I am trying to smoothly increase the frequency of a sine wave as an example.

Smoothly interpolating between two speeds involves fully performing calculations, that use time, and interpolating their results.

Hi Deathrey,

When you say interpolating between the results, would you take the first speed and the second speed’s output and interpolate between those two points? Or how would you suggest calculating that interpolation? Thanks!
