I`ve tried with "animation condition" and without.
I`ve tried also "animation trigger" (between and mask).
And i`ve tried a combination with both. The animation start once after loading the fs, never with my frequency
Try without using an animation condition or secondary animation condition. Only use the animation trigger. Then select between and enter the same value twice. Remember that a frequency of 112.35 is entered as 1235h in the tool.
Then it should work. After you select the frequency the animation should play once. Once you unselect it, the reverse animation will play. Before each animation starts there can be a delay of maximum 55 seconds depending on how many frames you use for the animation.
