Hi Matthias, Chris and all.
Thx for your input on this..!
Yep I remember your take on this, with your examples...
and yep it works nicely, for Trees or similar that you can disable the
'Pitching' for..(and maybe also need some scripting, which shouldnt be
needed , the tool itself should work set things up..)
Those can be placed anywhere.. and behave as they should and still face
the
LookAt..! (as long as the 'LookAt' is created so it works in 'Heading'
and
that also 'Pitching is switched OFF)
(This makes it possible to place both the Target and the LookAt
Anywhere..)
As soon as you need both to work at same time.. both Heading and Pitching
(even if you only need Heading to pass the +180, -180 deg anglepoints and
stay inside those with the (known) problematic deg limits of the
Pitching,
you cant..! =( since when 'Pitching' is on for the 'LookAt' it also mess
up
the Heading... !
And this makes it impossible to move the Target away from its creation
pos..
When you now with Pitching checked.. then it mess up the Heading.. (when
you
move the Target Object(s) from its position where it was when bound to
the
'LookAt'..)
So as I see it now, for getting both Heading and Pitching to work( look
up/down and Side2Side)
Then Two LookAt are needed (both with 'Pitching' Disabled and one of them
Rotated 90 Deg BEFORE Binding the Target Object(s) to it..!)
Your tip on set the init and then move is a good one, to add to that one,
for doing this for many Target objects in one go, (since the actual
'Chor'
Win dont support MultiSelection in SP3..)
You can MultiSelect all needed Tartget Objects in the 'Select' Win and
then
in the 'Animation' Window, in the bottom of the screen, change to Init
chor
in the Chor part of it..!
(I even have a the change of Current Chor, bound to keys Up n Down Arrow
keys..=), to switch fastly between needed chors..and that for many
objects..if you keep the Chor structure similar and wisely, then you have
alot better control then in the actual 'Chor' Win..)
(These are things I had planned for my Char Anim tut..,whenever that will
happen..)
btw..
If one apply your tip on setting the Init.. and also set Pitching to OFF
then you can select one of the bound Targets, then use the Lattice
'Paste'
too or similar to spread out copies, and then multiselect them and as I
pointed out set them all back to 'LookAt' chor or a chor after it.. and
all
copies will work fine with the and face the 'LookAt'...360 deg..=)
More takes on this later .. now I am off again..
Take Care
