meshsmooth problem

[gnarlycranium]

Meshsmooth seems to interpolate curves between the edges that it sees next to each other-- it's not smart enough to know that you want to keep a larger curve consistent. I think that's what NURBS are for. As far as I know, there is no way to prevent this, it can only be minimized by increasing the density of the base mesh so the interruption of the grooves aren't spread over as wide of an area. It's darn frustrating. :annoyed:

from my little experiance
........

in your images it looks as if some of the vertex are not wald and remain open . maybe a good idea will be to go over the cut you hv made and wald them and then try to increast the iterations

it might help i think

Thanks for the feed back. All the vertecies are welded. I overcame the problem by tweaking the subobject level in the meshsmooth modifier.

It seems to me that there is no "standard" way of addressing this issue. Am I correct?

[gnarlycranium]

As far as I know, there isn't. Polys are lumpy. Subds are better for organic shapes than mechanical-- the best tool for mechanical objects is NURBS.... but from what I've heard, MAX NURBS stink. :shrug:

You're not doing anything wrong, this is just how sub divs work.

You have three options to get the sharp edge you want in Max.

1. Chamfer those edges slightly before meshsmooth. This will force the meshsmooth to interpolate the smoothing through that chamfer and help retain it's shape. This results in quite heavy meshes.

2. Use smoothing groups to control the meshsmooth

3. Use edge weighting and crease functions in the meshsmooth modifer.

Thanks for the tips! Ok, so here's what I understand..

- Polygonaly modelling is best for organic: human forms, etc.
- NURBs are best for mechanical obejcts; cell phones, electronics, etc.


When does Patch modelling shine? (is patch modelling the right term?) So far, I've focused on polygonal modelling in max, because I am fairly comfortable with the workflow.

[gnarlycranium]

I've never used Patches myself, but from what I've seen they're another method that's good for organic things. I think it can be used for some NURBS-like applications, but I'm not too clear on the link or similarities between the two.

can't you just do a boolean after meshsmooth?

[gnarlycranium]

For an in-depth debate on the trials and tribulations of modeling mechanical objects with meshsmoothed polys in MAX, take a look at this thread in the 3ds MAX section (http://www.cgtalk.com/showthread.php?s=&threadid=39739).

here i've done a boolean after meshsmooth.
what's the problem then?

[Shu]

try doing that with beveled edges...
