Thanks for that. I'm not sure we have the time on this current project
to hack around but will certainly give it a try in future when things
calm down. We may get away with clever comping in this particular
situation. It is a pain, though, isn't it. I'm sure its on everyone's
wish list that this would work fairly effortlessly as freelancers'
availability and the relative strengths of the various packages mean
that you would like to mix up the software used on a particular project.

Hi
Alastair,
I was originally suprised as I couldn't get it to work. But eventually
I did. Having said that I wouldn't recomend this setup (unless your are
really stumped)... but it does work.
I use XSI-> collada -> maya to transfer fully rigged characters
from XSI to Maya.
I did this for a 3D realtime engine we are develloping on a specific
platform (with converter only supported on Maya).
The main steps are...
1 - Bake/plot animation transforms for influences on a complex XSI rig
(any rigging is fine).
2 - strip out the influences, reparent them according to a simple FK
hiearchy (or your liking... mine is coded to read an xml descriptor
file ... because everyone should be using xml).
And re-apply the animation to your influences.
3 - export out a collada file out of XSI.
4 - BAD, VERY BAD... edit the collada xml file to fix it. I automated
this, as I found collada Maya format and XSI collada ARE NOT
COMPATIBLE.
I metioned this to both softImage, and Feeling software, and got a
positive response back from Soft, leading me to beleive Feeling
Software, does not really care to make Collada truely cross platform.
5 - Import into Maya, voila.
Did I mention Collada, doesn't work between XSI and Maya.
This needs to be fixed, but so far I haven't heard any response from
the Maya/Autodesk camp on this. Its regrettable because it can be made
to work.
Since the collada file is xml based it can be fixed. I did it by
hacking it, and it was very painfull exercise in xml parsing and
replacing tokens, and for some reason some of the animation coming into
Maya is still lossy. Also mind you my characters were game resolution,
not gigapoly,
or supped up rez.
Not a very pretty solution for a software that is supposed work between
all major softwares. And I hope the Collada group looks at this MAJOR
problem, or at least someone at Feeling Software gives a call to
someone at SoftImage.
I will be trying to use the .xsi transfer format for my next attempt.
Cheers,
RSM

Hello
This has probably been covered before but I wasn't paying attention.
Has anyone successfully used crosswalk to get an enveloped character
from xsi to maya?
I haven't so any advice would be gratefully received. I have a 5
trillion polygon character made up of millions of separate bits so
using any sort of shape baking procedure is probably out of the
question. As usual I am testing out the principal simply on a sphere
and a 3 bone chain. I have tried all 5 export optopns in the export to
maya option under crosswalk My incompetence is taking me by surprise.
Can anyone help?
