1/ Including all features that are making material editing and having the visual feedback directly in softimage are welcome.
The current XSI plug-in SDK is too limited to allow us to build a material editor inside XSI, like the other plug-ins have. However, we're talking to Softimage about what we would need and probably the next XSI version will be more flexible in this respect and will allow us to have embedded materials.
2/ Camera improvment. Maybe creating a maxwell camera with shifting and all options relative to maxwell (Zclip) as a standard would be cool. One thing that particularly disturb me in xsi is that you can't get camera option like 30mm (you always have an angle measurment instead)
I'm not sure I follow you here. The native XSI camera has Z clipping and film offset (well, they call it "optical center shift") and those are visible in the viewport and are used by Maxwell. It also lets you specify focal length in millimeters, not as an angle of view, and film size. The focal length, film size and and film offset features can be used by enabling the projection plane on the camera.
Maxwell-specific camera attributes are added to the camera object when you select it the first time. They are related to exposure and diaphragm type so they can't be previewed in the viewport even if we make a Maxwell-specific camera.
3/ Last but maybe the most complicated would be to get maxwell able to work in the pass system from xsi. It seems that right now you can define a pass with maxwell as a rendered image. You can composite thus maxwell image through the FXtree with for exemple a wireframe image.
Having acces to mxi image here and getting maxwell "ops" to adjust iso, lights etc would be amazing ;)
We plan to integrate Maxwell as closely as possible with the compositor module, but I don't have an ETA for this feature yet.
Bonus: would it be possible, but it here more belongs to mawxell than to xsi to have the ability to define a material for the cut (zclip) part so they do not appear empty? Then rendering it as a "pass" then i'm happy ;)
As you already said, this is a renderer feature request, not a plug-in request. :) It has been asked already, but I don't know its status. I can't find a thread for it in the wishlist forum
, you could post it there to get better feedback.
