Just select the property, and click the 'list' button. For other numerical properties (including transformations actually) you can use the 'list' tool of Duik, which is available in the link & constraints panel (in standard and expert mode only, it is hidden in rookie mode).You can then connect the transformation of the null object, and you can repeat this process for each new connection you want to make. position, rotation and scale), the quickiest and easiest way is to use parents: for each new connection, add a null layer, and parent the already connected layer to this null. If you're trying to connect transformation properties (i.e.The solution depends on the type of property: Your problem is that you want to make several connections to the same property, which is not (yet) possible (I'm thinking about how to make this possible, maybe one day I'll find out.). When you connect your slider to properties, if you have only one connection to make, it's pretty easy: just do your animation and connect the slider. I'm working on tutorials about these kind of stuff, I'm trying make this available quickly but it's a lot of work
