I don’t understand the probability percentage. If I have 3 transition destinations at the same point in timeline and I want to randomly select any of them, weighted equally, how can I do that? If I set them to 33.3% and I press play, sometimes the playback head goes past all 3 and non is selected? Thanks ---

Hi, A solution may be setting the `first` transition posibility to `33%` ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/4/46f32b0bc91c3379e1ea8b0ced7843981f50426e.png) The second to `50%` ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/b/bc84e22162e4d32cb53f1d069f0d8aacb179d3e6.png) And not applying any probability to the last so that it always traisitions to at least on marker ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/4/41ee5bc4cc31953789c7e5b42d70f31670cae56f.png) Hope this helps! ---

Ok thanks. So the general rule of thumb seems to be: Lets say you have 6 different markers and you want to randomize equally between them. First marker 100/6=16.6 Second marker 100/5=20 Third marker 100/4=25 Etc ---

Correct
