you’re right, adding a negate (between the passed history value of the rotation velocity vector and the w input of the Rigid Dynamic tag) appears to solve it. I’d have to study it to find out if that’s the solution really – It’s probably more obvious if the example doesn’t have rotation in all 3 axis. Maybe if the vector is broken up into HPB values…

1. the camera doesn’t follow the bus because the target tag is attached to the camera null so the null is targeted but the camera isn’t lined up with the null’s z-axis – easiest thing to do is put the target tag on the camera directly. Next problem is you are targeting the bus null, which does not move. Target the front or back of the bus instead (you can’t target the joint either since it is also in a null which does not move)

2. the joint section jumps because the Constraint tags which control the location of the Joint splines are being evaluated after the align tags so the bus parts move but the joint bits don’t move until later. Increase the priority in the Constraint tags to something greater than the priority in the Align tags (1 is enough)

3. you are controlling the position of the bus by the Position in the Align tag of the front part of the bus. You can’t add more points because the spline is remains the same length. You could add more keyframes to the Position parameter but it’s really hard to do that smoothly, it’s easiest to use few keyframes but to control the speed of the bus between the keyframes with the F-Curve.

I do not know from personal experience but I’ve heard that Lynda.com has not bad beginner level stuff.

The last of the OSX Tiger updates was 10.4.11 so I’d upgrade to that, if that doesn’t help contact Maxon support.

To match what scene AO does put AO in the Diffusion channel (but you can put it anywhere for different effects).
I would put it on objects that need it (the racks etc), try the scene without any AO at all since it’s real reason for existence is to fake GI – that’s not to say that they don’t go well together at times but sometimes both together can be a problem (and I’m not sure that’s what your problem is, it’s just a guess)

that doesn’t so much flicker as crawl… and at a distance (close) where it shouldn’t be that much of a problem. Do you have Scene AO on? If so, try turning it off and put AO into the materials where needed (the racks etc.) As a quick test try the walls/floor/ceiling only with AO or GI, not both.

weird, it works with 10.5 and 11 on 10.56…. ….which Timeline?… It works in the Timeline Window and in the Animation layout but not the timeline in the Standard layout

Go to the Dresser tab of the Cloth tag and turn on Dress Mode and relax it, then set Init State or Fix the Points depending on what you want (check the help).
Remember it’s a simulation, if the cloth isn’t completely relaxed yet once you start again it will continue to fall unless you Fix the points but then you don’t have cloth anymore and you won’t be able to remove it ‘naturally’. Another possibility is to set the Init State and turn off the Gravity until you want it to behave like cloth.
