This is what I did so far:
I made a hand controlled by sliders. I used link with for the rotations of the bones, which gives a l_fcv([slider name]) function. I make action sources from them, by doing Store > Marked Parameters All Sources. These sources are used in the mixer. This was all done under the scene root. So far so good, everything works.
Now the problem is, I want is hand under a new model, together with the actual action source (makes it easy to export). I made a model called hand, with the hand parented underneath it. I also copied the action sources under this new model. I made action clips on the mixer of the new hand model, but it doesnt work.
I think I know what the problem is though, but I dont see a simple solution, other then restarting the whole thing. This is what I think it is; When I look at the value in the source of the action sources it says l_fcv([slider name]). I assume that this should be l_fcv(Hand.[slider name]), with Hand the name of the model. When I put it there manually it still doesnt work. This would be, I guess, because XSI sees this as a new function.
I hope this question is clear. If you know how to solve this, I would be forever thankful, cause I dont feel like redoing everything again.
