One might have some luck creating presets for lights and
materials in both Maya and XSI.
The way materials are assigned an organized is different
in Maya, especially with things like trying to use clusters
for materials and such but also with slotnames and types.
Crosswalk is good enough to transfer simple networks,
like a phong with a texture in the diffuse/e.g. color slot,
from there one could replace the material with a preset
saved. Those presets would have to be created best by
having Maya and XSI open side by side for comparison.
I think the effort required would still be quite huge.
I don´t know about custom mR shaders.
In regards to lights, I´ve transfered basic lights
between apps but had a lot of grief with stuff like
exponents, cone angles, fallof and the likes.
Ended up redoing pretty much everything using the
imported stuff as a guide.
Arealights and environments might even be worse...

P.S: There is a script on highend3d.com that makes
instances unique geometry, you might want to look
into something like that, or replacing the instances
with plotted nulls if possible, then reattach your
actual geometry in the other app?

I don't think you can import Maya particle simulations. If you're doing
instances, then you should plot animation on the instances and export
those to XSI. Then XSI can treat them like any other object.
As for the shaders....not sure how they're compiled/linked in XSI. If
they don't rely on any XSI specific technology, then you might be able
to convert the shader .spdl files to .mi files and use them directly in
Maya as long as you match them with the proper version of mental ray
running in each application - the latter being the trickier part. If
that doesn't work, then you're next best bet would be to write your own
shaders and compile them for both XSI and Maya and make sure artists use
only those shaders for work that has to cross the bridge.

Subject: particles from Maya to XSI, ligthing from XSI to Maya?
2 XSI/Maya info transfer questions :
1 - Any way to transfer Maya particles to XSI. We have a Maya
particle simulation using instances that we would like to light and
render in XSI. Any easy way to transfer them or do I need to write my
own tool to do it?
2 - Any way to transfer XSI/Mental Ray lights and shaders from
XSI to Maya? It's for the same problem. We figure that worst case
scenario, we set-up our lighting/textures/shaders in XSI and then
transfer them into Maya for rendering.
We would much prefer option 1 as we have much more XSI licenses
then Maya licenses but I'm curious about both. Any tools and/or options
I should know about??
Thank you in advance.
