Hello,
When you create a animated part/control/object for a VC, such as lets say 'lever_throttle0', you would Attach it to;
* Animation Manager with its proper Animation key length (zero through 100, or in this case, zero through 50).
* Attach 'Mouse Rect' which will activate Mouse controls (if programmed into the Animation via the master Animation parts XML list).
Now, Attach Tool doesnt always work. Perhaps 1 out of 5 times, it will not always attach a code to a part, from animations to effects to Mouse Rects. So to check that it 'took hold', select the part, then Edit/Properties and click the second Tab of two at the top and read through the various properties that are coded into the part via Attach Tool. You should see all that you attached, from Mouse Rect to Animation. If Mouse Rect is missing, then try it again.
If you can type good, you can literally add Mouse Rect coding into that string, but you must know the code 'exactly' and you cannot copy/paste for some goofy reason. (Remember, it must be difficult... ARRGHH). oops, anyways.. Check there and see that your Attaches happened and if so, you are good to go.
Now, if they are attached, and you still have no 'mouse' over action occurring, then you have Polygons between you and the part, such as your visibility location being too far back and your face is in the head rest of the seat, thus creating a block and you cannot click on things until you move forward.
I had a switch hidden behind another on my last plane, and you had to move around it to mouse the switch. Very difficult, but I saw no other way to manage the situation aside from a alternate Panel view where you are at an angle to the switches and thus nothing was blocking you.
Hope that helps.
Bill
