Turn versus Roll methods

[lanceA]

Create a new world and instantiate an object of Alice and Bob (people folder). Place them side by side so one is on the right and one on the left and invoke a .turn to face camera method on both of them. Select Alice's right arm and do a .rightArm turn--> backward-->1/4 revolution.

Now select Bob's right arm and do .rightArm turn-->backward-->1/4 revolution.

Alice's arm extends outward toward the camera. Bob's right arm 'appears' to go behind his back. Why ? However if I do a .rightArm roll -->left-->1/4 revolution on Bob's arm it points at the camera the same as Alice.

At first I thought it might have something to do with having to go through Bob's upper body (as seen in the Object Tree view) to get to his arms. However when I performed the same tests on each object using their right legs I got the same disparity in direction.

What am I overlooking? Thanks in advance

Ha, you loser.

The direction the arm swings when commanded to roll or turn right depends on its orientation when imported into Alice.

Ha, you pompous ol' windbag.

For example, if the object is imported with its arms held out (see pic), then turn backwards will "twist" the arm, turn left (with the right arm) will "raise" the person's arm, etc.

Haha, I think I'm cool, but that's not true. :(

If when the person is imported, his/her arms are held at his/her side, then the movements are more predictable.

The Students that created all of these objects don't seem to have had a blueprint for accepted stucture, so the axes of the various subparts aren't always facing the same way to start. Notice in the attached pics that the front axis of Bob's left arm points left, while the front axis of Alice's left arm points forward. These inconsistencies lead to frustration as you have already discovered. I just jigger around with them until I get the position I want, and save a pose. So I don't have to do it again, I save all my enhanced objects, and use "them" in new projects rather than the originals.

Ha, you loser.

Not nice to call somebody a loser when they do not know the answer to a problem, especially when it is not their fault. The forums are here for us to ask questions and answer questions, not to make fun of somebody for not understanding something. I know that not many people like LanceA because of his opinions he has had on other subjects in other posts, but it does not give us the right to attack him like this. He had a question and should be treated like anybody else here on the forums that has a question.

I wasn't saying that because he didn't know that, I said it because of all the crap he's done before.

I posted on this thread shortly after the DDR one, where he vigorously attacked Ping over copyright stuff, so it was me saying something useful while stating my dislike for Lance.

I was not insulting him for asking a question; it was kind of a follow-up to his posts on Pings's thread.

Oh well. I'll edit it, if you want.
