TS 7.6 - WORKSPACE:


I have carefully read the manual (chapter 8, page 42) about mirroring limbs for skeletins and carefully set the shoulder and leg joint limits for receiving the arm and leg. I have carefully tagged everything including left/right symmetry. Yet when I mirror the limb over, it is always flying out at a stupid angle and rotated 180 degrees from where it ought to be.


Then there is no way to take hold of the whole limb and rotate and swing it into proper position. Instead I have to move each joint as a single point. In the video tutorial, the problem does not seem to occur, so I keep thinking I am missing something, but I haven't figured out what it is.


I previously tried this with some simple skeletins just to see if I understood the instructions and the same thing always happened. The mirroring doesn't seem to include orientation.


Thanks for any clues.

If you upload your Limb Library, I will take a look at it.

Thanks, Trueblue.


Here's a ZIP archive containing all the contents of the "Biped Limbs" library.

Here is your Limbs fixed. I had to adjust the rotation for all of the connecting Joint's Matrices. Drag and and Drop the Skeleton into the LE and then double click the Arm and Leg limbs from the library. I can only guess that the connecting joints were rotated inadvertently.

Thanks very much Trueblue. I have experimented further and I think the problem is that when the skeletin is first created, the joint limits are not mirrored and I find it impossible to exactly mirror them by eye. I think in my attempts to make the right joint match the left, I reversed it (or something).


But even when I got it turned around correctly (as you did), I found I could not exactly match the position so when I added the second limb, it's position still had to be adjusted to match the symetrical skin.


It seems to me that it would be very useful to have a tool or procedure to mirror the joint before adding the limbs. For instance, it would be nice to be able to CTRL drag the left shoulder joint over to the right shoulder joint and presto! the two joints would be perfectly mirrored (as far as joint limit settings) and ready to receive mirrored limbs.


Or even better, it would be nice if the mirrored limb simply mirrored the orientation of the original limb.
