Thanks for posting. I have been trying to figure this out since you have posted your 8 point mask effect but I gave up. Now I know.
In addition to this you can make on screen controls.
Here is how:
- Make a new group and call this group On Screen Controls
- In this group you add a rectangle shape the same size as you project dimensions
- In the shape properties uncheck the fill for that shape to make it invisible
- For every Track Point add any filter to that group that has on screen controls. You would need a filter with just a position on screen control, for instance the Bulge efect (in the Distort category)
- If you also want to adjust the position and rotation of the whole group that holds your shape (in the case of the tutorial that would be the triangle), you can add the Scrape filter (in the distortion category) to the On Screen Controls Group.
- Set all the mix and amount sliders of the filters to zero in the inspector, just to be sure they don't have any effect and make shure that there is a check in the "Publish OSC" checkbox.
-Rename each filter to give it a descriptive name.
- Use the Link behaviour (in the behaviours/parameter category) to link each Crosshair's position parameter to the X and Y position of one of the Bulge filters (two link behaviours per Crosshair, one for the X and one for the Y)
- In the inspector set the offset for each position parameter to - 0.5
- In the same way use Link behaviours to link the position and rotation of the group that holds your shape to the position and rotation of the Scrape filter.
Now it should work when you open the generator in FCPX (I'm writing this while I am not behind a Mac with Motion 5 on it, but I think I mentioned all steps. If not, it will at least put you in the right direction)
Hello guys. I am new here. I am trying to do this as well but link the x and y of a drop zone to an OSC. O have followed the steps above but to no avail. The closest I get...the OSC ends up in the bottom left corner.
