Can any of these files types be converted for use in XSI?

.DXF (Auto CAD/3DFace)
.VMRL (VMRL)
.X (Direct3D)
.COB (Caligari Object)
.MQO (Metasequia Document)
.SCE (Soft F/X Model)
.RDS (Ray Dream)
.POV (POV-Ray)
.SUF (DoGA CGA System)

I have models in a 3D program I use for film and they can be converted into all those formats...can XSI use any of them?

Alpha, I'm pretty certain that Biturn would handle some of those formats, such as .DXF, although I'm not sure how well...

I can see biturn importing the format I have, but I can't see it exporting into XSI format.

It handles some of the earlier XSI versions, as well as 3dsMAX format, and that can be imported into XSI.

DXF files usually don't have any UV maps, so going that way may not be a good idea.

DXF didn't work. I got it in 3DS format to t551' and we got the models to work.
