MoI is using Rhino's 3DM file format. So, yes the files can be opened by both. But Rhino can support a lot of things which MoI does not. I believe MoI ignores the unreadable objects and property data, but leaves it remaining intact. So it can still be opened in Rhino once again without a problem. You might want to check with Michael if you plan to bounce back and forth between the two programs using same file.

Hey Jonah! thanks for the information.
The issue that is coming up, and I should have mentioned this...
is that the client is using hypershot for quick renders. But the model
which is made up of multiple pieces is coming in as 1 piece when I save
as obj..... so I'm looking for a way to give them the model so that it
retains is multiple groups....

do you know what I mean?

thanks

Mike,

I use MoI with HyperShot. You need to do the following (copied from the MoI Support page)

Download:
http://moi3d.com/download/SeparateOBJ.zip

This will edit an .obj file to break objects down into smaller pieces to help with material assignment in some other programs such as Poser, HyperShot, and Bryce.

If your .obj file was exported with default settings, this will break apart pieces between any sharp edges. For example, a box will break apart into 6 different objects. But if you have rounded all the edges of the box so they are smooth, it will remain as one single piece.

However, if you export your .obj file with "Weld vertices along edges" unchecked (expand the Meshing options dialog with the arrow in the bottom-left corner to see this setting), then that will set things up so that all surfaces will be broken out into individual pieces, including pieces that are smooth with one another.

To use the program, unzip it to some folder, then run the SeparateOBJ.exe program. It will ask you for the name of an .obj file and after you give it one it will edit the obj file to break larger objects into smaller object pieces, and also assigns separate material ids to each piece, which HyperShot needs to have present to assign materials to different pieces of the file instead of just one material for everything.

(Hoping this will become a MoI "save as" option some day :)

Hypershot has a direct plugin for Rhino now! So does your client have both HS and Rhino? You could avoid all that OBJ mess then...

Hey Ed/Jonah!
thanks for the further replies.
Both are very helpful.
Ideally, I dont want to dish out my source files, or anything that could be used
to edit the model files.
So I think the obj. seperator app will work perfect for this!

thanks again guys!

Mike
