briefcase

I need some suggestions for this WIP. How could I deform the briefcase? In this form it is to clear. How could I realize the stitches like the original?

Regards

Michael

Hi Michael - typically you wouldn't want to model small bumpy details like stitching in MoI. Instead normally small details like that would be applied as texture or displacement maps inside of a rendering program. Or sometimes applied in a brush-based displacement program such as ZBrush or 3D-Coat.

You can still use MoI to create the base form, but for the deformations and stitching you'll probably want to refine those in a polygon-based program instead of trying to model them explicitly in MoI.

Hello Michael.
I will try some tests in 3d-coat and show the results here.

Hi Michael - a couple of tips when exporting to 3D Coat:

I don't think that 3D Coat (or ZBrush either) likes to handle N-gon polygons, so when you export, set Output: Quads & Triangles instead of Output: N-gons.

Also both 3D Coat and ZBrush don't really like to have large sized polygons that span a lot of area. So you generally want to use the "Divide larger than" option in MoI's export options to divide up any polygons larger than a certain distance to prevent any large polygons in the result.

See here for an example:
http://moi3d.com/forum/index.php?webtag=MOI&msg=1549.4


Those options can help make things work better in the detailing application.

I think the comments about the ability of 3D Coat to accept file types/settings may be somewhat out of date The V3 Alpha is at version 47!!!!!.
Far superior to allmost any other app I would suggest--- now!

Anyway, if we had the original files of the making of the file box I can envisage making some modifications to the shape without going into another app any way..

Will try and show soon.

Is this a better start in MoI before taking into a 3D displacement app as an .obj file?

Carrara/3D Coat etc?

Hi Brian, maybe 3D coat is different, but it is not unusual for a program that focuses on doing displacement of mesh vertices to expect to work on a mesh that is subdivided into small pieces.

Sometimes there may be tools to do subdivision inside the detailing program itself, but by that time the original NURBS object is not present in there, so it can be better to do the subdivision as a more initial step when you export from MoI, since MoI has the original NURBS data.

That allows MoI to place the subdivided points directly along those surfaces. Instead what may happen if the subdivision is done only on polygon data is that it may use a kind of "cooked up" smoothing which may cause intentional sharp edges to be lost or it may subdivided polygon into flat regions which kind of makes a shape with flat pieces in it like this example.

Definitely with ZBrush it works better to subdivide at export time from MoI. I thought it did with 3D Coat too but I'm not completely sure about that.

Is this of interest/value?

I saved the above 3dm work as an .obj file--see image in Carrara.

I took that same .obj file directly into 3D Coat, and, without doing anything, everything at default save settings, resaved as a new .objfile --see the second image.

I just love how one can avoid needing to get involved with UVs making in 3DC!

Hi Apophis,

I modelled some stitching in MoI, but It was only a small amount, I don't know if I would attempt a whole briefcase though.
The texture was applied in the rendering software.

Thank to all for your answers. 3d-coat isn't a good way for this. Semaour would be nice if I had Maya. Anyway, I will try the DannyT way.

Stiches are one of the specialities of 3D Coat.
Even Chains!
