Hey everyone.  I haven't had a need for CSGs in Moray before because I
haven't been animating in it (until now).  I've found the CSG section in
Moray's 'help' file less than adequate.  Is there a good tutorial anywhere
on how to make characters with CSGs, set limits, get them to rotate
properly, and not have the objects jump to new locations when I add them to
one another?
Thanks a lot.

I don't know about an available tutorial, but there are a few simple rules
you have to follow (identical to those of POV-Ray):

- always build your CSG's at the origin, and only afterwards transform them
to their proper size/orientation/location
- always follow the golden rule of transformation: scale - rotate -
translate, in that precise order
- if necessary, move the CSG's axis origin (by switching to local
coordinates)
- incidentally - although this is slightly off topic - play with the limits
and freeze possibilities

I hope this helps a bit.

Thanks Thomas. (^_^)
It's no in-depth tutorial, but definately gives me enough to experiment and
find my way with.
Anyone else reading this thread, if you have anything to add that could help
me out, please post.
Thanks again to Thomas and anyone else who posts.

Derek

It is short indeed, not really a tutorial. Sorry for that.
One additional issue might be if you have moving parts in your CSG's, then
Inverse Kinematics is required. Not difficult to do, but needs some precise
building. I believe there is a fair tutorial for this in Moray.
I have not made any animations in Moray, but all this is valid for that too
I think.
If you have any specific problem, don't hesitate to yell :-)

Thomas
