Re: Maya - what were they thinking 2 - transforms

[Anto Matkovic]

Whatever works for you. For example I never tried to key the global transform 
in SI, always used constraint instead, because this clearly shows what's going 
on. Also followed 'one object one transform' 'rule', that is, never more than 
one constraint or expression per object - this makes it easier to connect to 
another structure, reset, so on. But that's just me. It's always possible to 
hide some null, after all.

Hi Jordi,

Quick question, is the new transition guide expecting a release soon?
Looking foreward to it.

1. Create a new ROP
2. Create a bundle
3. Place bundle in Rop / objects / forced matte ( or whatever its called.)
4. Render new rop.

Re: Maya - what were they thinking 2 - transforms

[Anto Matkovic]

There's neutral pose in SI. However, that ''hidden parenting'' could be a risky 
business, too. For example, XSI built in biped rig creator has a nasty habit to 
''zero out'' the rotation of COG (hips) controller. So, by moving and keying 
that controller horizontally, in Animation Editor there's a slight small 
movement along Y axis. Or, zero Y movement in animation editor is small up - 
down of cog bone.
Somehow contradictory, to use these hidden offsets properly, someone has to be 
able to visualize them.
As some rule of thumb, positional offset is more or less harmless, rotational 
offset is ( more or less) dangerous. SI has nicely exposed options to set 
neutral pose only on position. In Maya world, let's say that Maya pivot is OK 
to use, as only positional offset. While Maya Joint Orient, as rotational 
offset, it is a problem in many cases -  setting that thing to zero, whenever 
is possible, is condition for easier life...

 Hum.
 
 I guess these "intermediate items" are probably part of XSI's internalized 
abstractions (?)
 
 I'm sure there must be advantages of having it this way, (1 null (& hierarchy 
level) for each axis of rotation ?)
 but I feel that these abstractions remove quite a bit of redundancy and 
clutter in sometimes already quite cluttered and deep hierarchies.
