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?
