Render trim surface?

[blank]

How can I render a trim surface, that was imported in xsi 1.5 from maya?

When I import the trim surface into xsi 1.5 the wireframe looks o.k. but when I render the trim surface there is no trim anymore? Can someone help me?

sorry for my english

Bonjour Blank,

As far as I know, trims are still not supported in XSI (even in version 2).
Sorry!

What makes me creazy is, that you can import a trim surface and it looks o.k. and that also in the tesselation area there is an option for trim surfaces, but when you render it, it does not work

Yeah I know!

But seriously, any developper has to make decisions on what to develop, due to limited time and staff. I suppose that another reason why NURBS have not been fully implemented is because many XSI users still have Softimage 3D, and in SI3D NURBS are strong.

There is good news: From what I read in the XSI mailing list, NURBS are on the TO DO list of Softimage, so you should see it in the next release.

thanx! I'll stop trying to render trim surfaces any will wait for the next release. But if mentay ray for maya rocks, it could be that it comes to late.

I'm not sure that being able to render trims is a sufficient reason to use another package. I know, trims are cool, but for now you could use a transparency map.

Also, remember that mental ray is completely integrated into XSI, wich is not the case of Maya and 3ds max. This means that you'll never be able to reach the level of control than with XSI. Of course, if you don't want to develop shaders and you only want to use mental ray as it basically is: a renderer, well it's a question of tastes.

However, I would like to know in the near future if mental ray is as fast in Maya than in XSI, and what people think of the workflow/pipeline implementation.

we do have one licence for mental ray for maya and for me it is definitly not as cool as mental ray in xsi. that is one big point for xsi. I do like xsi and its user interface but i am definitly much faster in modeling in maya because I use it since release 1 so i do know it much better.
I imported a scene from maya and wanted to see how much better the renderer is and than there came the trims. It is really fast to trim a hole for a window into a wall, faster than to create a transparency map.
But you got right, this should not be the reason for or against xsi.
