Hi Jonah, I kind of need some more information than just your original screenshot to be able to diagnose the problem.

It could help a lot to have the .3dm file posted, and also some other information that I mentioned previously:



Also one other thing that may have an effect is if you are exporting in N-gons from MoI but triangles from Rhino... Maybe the way this function works in Modo makes it want to have a center UV point in there instead of only points around the outside...

I can certainly understand if you don't have time to do this right now, but it is pretty difficult for me to make any progress on this without some extra information.

Hi Michael. Might be a little while, but i definitely will send files to you because i would like to see it resolved if possible. Or perhaps it really is a Modo issue... Also i will have to add "all quad/triangles from MoI" onto the test pile...

Do you also want the Modo test file?

thanks,
jonah

Hi Jonah,

> Do you also want the Modo test file?

Sure, that certainly might come in handy for testing as well.

If you did have a big n-gon at the top there with the MoI export, then that is most likely to be the single biggest difference between the Rhino export and the MoI one. That would mean that Modo wants to have an actual poly vertex at that central spot to make it work correctly, it is otherwise trying to some kind of interpolation across a polygon which is not working right. Right now that is kind of my best current guess but not verified of course.

Hi Ed,
>>I use Hypershot for my renders. It is still a relatively new product and requires that UV coordinates come in with the import.

I use Hypershot also, but have had no problem so far. I always export the model as .obj from MoI, because no matter what Hypershot allows you to import it always converts it to .obj.

Cheers

Hi jonah,

>>It is a legitimate problem.

It sounds like Modo is a pain on this point.
Can a 3rd party mapper, such as UV-mapper help? http://www.uvmapper.com/ (there is a free version)

Thanks for the suggestion. But I'd rather not have to do any mapping at all. In that case, I'd rather just export from Rhino. Let's see what can be resolved using software which I already use... Modo actually has some nice UV tools, but missing something to handle a "revolved" disc...
