Hi Keith,

> many modeling programs not just Moi.

Yes, that's correct - basically it will be problematic to import OBJ files created by any CAD program. CAD programs need to have the rendering program use the vertex normals information that is stored in the OBJ file. If the importing application just ignores those normals (which come from the original CAD surfaces), and instead creates new normals just by looking at the polygon data alone it will result in shading artifacts.

If all the polygons are very evenly distributed and of almost the same size that also tends to reduce these kinds of artifacts, and since most sub-d models are constructed in that way sub-d models are generally not as impacted by this problem. That is likely why they did not realize they were messing things up when they changed how they deal with vertex normals in the imported files, because they probably only tested it with sub-d models and not any CAD generated models.

If you can find the "Surfaces pane" in Carrara that may be where you can find the control to turn off break-angle normal generation and possibly restore the original normals as described in that Carrara discussion thread.

Hi Ed,

I just read this tutorial. Fantastic work! I'm happy that my scripts helped you :)
I hope, I'll return to script development in the nearest future. Unfortunatelly I haven't free time for it now.

---

Thank you Max for bringing this added functionality to MoI. I'm sure your scripts will help a lot of people.

Help please,
I'm new to scripts and the forum. I downloaded scripts and copied and pasted into MoI's command file.
when I tryed subdivide, got- SyntaxError: Parse error
any help would be appreciated.

thanks,

Bob

Hi Bob - it looks like you have copied the files into the correct place. But it looks like you may have some problem in how the shortcut key is set up, do you have some extra characters in the shortcut key or something like that?

In the shortcut key, you should put in just: Subdiv_beta6

- Michael

---

That is is curious because all plugins by Max are something like _Subdiv_beta6 with a "_" as first letter!
Have you modified the name of the original script as shown on your list of files ?

Thank you, I was trying to use the detected buttons, but the shortcut keys work!
This is really a great addition to your program. I have friends that rave about Creo for product design, this seems to give a MoI another level of flexibility in model generation.

Thanks

Bob

Pllou

yes I did (my ignorance). Micheal's direction on the shortcut keys got it working.
I'm really excited to try out this new tools!

thanks for your help

Absolutely awesome tutorial - thanks so much for this!

Thank you so much for producing this wonderful tutorial Ed!

Definitely one I'll be putting on the reference shelf - and referring people to as a great example of just how capable MoI (+ Max's SubD) is.

Keep up the great work.

Cheers,
Hamish

Hey man...you did an OUTSTANDING JOB!!!!!!!!!!!!!!!!!!

I'll never be tired to say that....I love to see this project...in the right hands, this little gem of program can do really amazing things! :)

Great job, and thanks a ton for the tutorial!!!! :)

When I download the .zip file for the Bridge script I only get 1 file: _sBridge.js. There is no .htm file included. Is there something missing or is the .htm not required for the bridge command.

---

No need for the function Bridge : Generaly htm is used for UI, menu, parameter etc...
So make just a short cut or press tab then write _bridge (upper caser letter(s) or not but don't forget the "_") !!!

That's normal that there's no .htm file for that particular command.

The .htm files contain user interface elements for a command like buttons and checkboxes and stuff like that. If the way a command works is that it just immediately performs an action and doesn't have any UI for buttons and options or things like that, then it may not have an .htm file in it.

Hi
I found adding the scripts a bit confusing at first and struggled along installing them piecemeal before discovering there is a link that allows you to install them all complete with a new set of icons in Moi's UI. Oddly nobody ever seems to point this out despite the tools being present in some tutorial videos. I'm off to work now but you should be able to find them on Max's page http://moi.maxsm.net/startpos/8. And looking at this thread I'm missing a few:)http://moi3d.com/forum/index.php?webtag=MOI&msg=6507.1

I gave up on making a car when Carrara kept ripping up the smoothing. I found half an old model today so put some wheels on it and rendered it in Simlab. I like the smooth surfaces but I don't think I will finish the model as I feel like doing something new.

Moi is really amazing!
