Hi Michael,

This is interesting because I too have been pondering these same kind of questions?

I bought Silo awhile ago because it was supposed to be very easy to learn.
I'm sure that it is "if" you're used to doing SubD modeling, but I'm still unable to grasp the workflow & how to use it properly.
I think part of my "SubD learning problem" is because I've started out into CAD & 3D by learning with MoI & Rhino.
And because MoI is so straight forward, intuitive & easy to use, I found Silo tends to remind me of using Rhino, lots of Keyboard & Mouse clicks to do anything!
Wish there was a SubD program that worked just like MoI does!

In my CAD-3D-SubD ignorance I'd just assumed it'd be easy to somehow combine any MoI NURBS items with Silo made items.
This might well be true for those with more experience, but being so new to all of this, I still haven't managed to combine or produce anything as yet.

As a Jeweller, most of my work was hand carving designs in wax for casting into precious metal.
Here's some examples in wax of what I've previously hand carved.

My main aim now is to be able to produce similar designs, but by using just CAD/CAM.
Obviously these designs consist of both organic & geometric forms combined into one item.
The organic being the head or face section & the geometric being the accurate band dimensions & ring size.

I'm guessing that my answer is to just keep persevering with the learning of Silo & SubD?
So can anyone with experience in combining both MoI & Silo models together into one offer me some detailed advice on how's the best way go about it?

subd modelers are a really great tool for quickly designing basic volumetric shapes. You can often manipulate a shape faster in subd than you can in Nurbs. Then import the wireframe to Moi for use as a 3D reference to model your buildings accurately...

Hi Colin, yes I'm afraid that in general the "ease of use" of subd modeling tends to get rather exaggerated.

Subd tends to be quite heavy on a lot of fine tuning adjustments and point manipulations in 3D space.

Although the Silo authors have done a great job at their implementation, it is still by its nature a quite detail oriented thing and just takes a pretty substantial amount of time and especially practice before it will begin to feel more natural.

Actually the type of designs that you show there (which are very cool by the way!) are probably better to do with displacement-type brush stroke painting rather than subd vertex type modeling.

That's where you focus on painting-like brush strokes across your model, carving depressions or raising ridges with your strokes.

I believe Silo implements this as well, but ZBrush and Mudbox are different packages that are focused very much on just that style of modeling.

Possibly using MoI to model your base band shape and then exporting that into ZBrush for displacement painting might be your best approach for that type of thing.

Hi Jonah,

So in this case, I'd be better off to first do the organic parts in Silo, then import their wire frames back into MoI & finish doing the ring design from there?
OK, Thanks for that, I'll give it a try & see how I go.

Which leads us to the question ..... will V2 have solutions to mesh export that make it easier to
carry on in Zbrush ? More subd able meshes ?
Peter

Hi Michael,

Thanks for that info, it kind of confirms what I'd suspected & had found so far.

I'd only recently been looking a Zbrush & had been wondering if it might be the better option for me?
Thanks again, think I'll download the trial version & see how that pans out for me.
If Zbrush works out easy enough for me to learn & use, then that'd save me a heap of mucking around within Silo.

Hi Peter,

So far several people have been using MoI export into Zbrush successfully.

Are you having a problem with your exports currently? If you could post an example I could see what is going wrong in your particular situation.

In general it seems like other people have had the most success with exporting from MoI as an OBJ file using Output: Quads & Triangles. ZBrush does not handle n-gon output quite properly, so make sure to switch that off and you should be fine.

As far as I know typically the mesh that is used in ZBrush is then painted on directly, it usually does not have sub-d applied to it first...

If you want to have a sub-d type smoothing applied to your mesh (which kind of shrinks things down and actually alters the shape of your model), your best bet is to manually create that particular type of mesh in a sub-d modeler instead of in MoI, that is not likely to change in MoI v2.

- Michael

Hi Colin, I kind of doubt that you will find ZBrush very simple to use neither, but probably the overall mechanism of painting type operations will be easier than 3d point manipulation type stuff.

It is probably a better place for you to spend time on than subd modeling because it should ultimately provide a much quicker and smoother workflow for the type of things you are showing there, once you do get comfortable with it.

Hi Michael !
Yes I use the quad and triangle setup and the results are not bad at all..
It just needs an awfull lot of dividing and the resulting polygon count is pretty high !
I just did a fast example of a ring in moi and a fast render in Kerkythea... to show that
there is quite some deformation possible !
Peter

Hi Peter, it looks like that should work pretty well!

One other thing is you may want to use the "Divide larger than" setting when exporting from MoI to cause the exported mesh to be diced up into smaller pieces.

You can put a distance into that "Divide larger than" setting, and any polygons larger than that size will be broken down into smaller pieces.

So for example, if you set "Divide larger than: 0.5" - any polygon larger than 0.5 units in size will be further subdivided during the export from MoI.

- Michael

Yes Michael thank you !
I had that problem with the car too !
But its a good way of sub d ing things more into a zbrush friendly shape.... !
Thanks
Peter

Sorry. I wrote that just before you posted the images and description of those character rings. For something like that, i would do as Michael suggested. Model a single surface Nurbs shank, export as quads to Silo, then add extra geometry (extruding, spinning edges, etc) to build the basic volume of the face. Then sculpt the fine character details...

In a general way (and reading a post about using Silo/Moi for architectural purposes), then i suggest roughing out a shape in subd. Since you also have Rhino you have a another set of excellent mesh refining tools. So you could easily boolean a Moi mesh together with a Silo mesh, then use Rhino tools to adjust the transition area. Or even send it backwards to Silo again for smoothing with the sculpt tools...

My currently basic apps are--
PhotoshopCS3
Carrara6.1Pro
MoI
3D Brush (THE zb alternative!)
Hexagon(The updates currently due should be wow!)

Put into my "disapointed" list are
Silo
Amapi7.52
ViaCAD

Colin, definatly try 3DBrush out before you try ZBrush. much more affordable and easier to use.

Thanks xrok1,

I'd already downloaded & tried looking at 3D Brush, but my present Video Card is old & didn't meet the minimum specs, so it wouldn't install properly.

Strangely enough that same old Video Card appears perfectly able to run the Zbrush Demo at present??
I intend upgrading my computer in the near future, so I'll need to take a look at all this again then.

regards Colin

Brian, You say you are disappointed at ViaCAD. Why?

jfallie
I find ViaCADs working methods quite clumsy and un-natural for me. And that 2d/3d setup where you accidently/continuously loose your nice friendly UI work setup you have organised---just too frustrating.
