I am trying to figure out how, Mirror works in this program.
In the select sub-menu, I am trying to figure out how select along symmetry center works.
When I select the option, nothing seems to happen.

The object I am trying to achieve, select haft the mesh, delete it, and to reproduce the other side with mirror.
Flattened seems odd also. Mainly, I'm trying to flatten it on the X. axis. But, by the looks of it.
The Y. axes, look like it needs flattened also:



As you can see, there is a big slit in front of the skirt.
I'm just guessing. But, I think if I could flatten it on the X. axis before  mirror. It would fixed it.

In the prospective view (your right, her left). You can see how the spline goes in front of the strap, on one side.
And goes behind the strap, on the other side.
I'm hoping flatten on the Y. axes will fix it? "Both straps should be behind the spline."

Hi 3dwizzard,

I am trying to figure out how, Mirror works in this program.
Select the object that contains the mesh you want to mirror (an object can contain multiple sub_object meshes).
If you want to use object or mesh space mirror, you need to set object/mesh pivot location for mirror. While still in object mode, use "Pivot" command to set pivot.
Change to sub_object mesh selection. Enable "Mirror" Choose mirror axis and reference space, then click on mesh to mirror.

You first need to be in symmetry mode.

Flatten will flatten a selection to a plane calculated from the average normals of the selection.
You should either use the scale manipulator or the "Align" tool to set up the object/mesh edge for mirror.

I'm not sure what I'm doing wrong. I'm still getting the opening at the front of the skirt.

Something I noticed in the wireframe. The outline is highlighted in blue. At first,
I thought it was the splines. Not sure what's going on there.



This is a tough one.
I'm working on a html, showing step-by-step what I'm doing. Should have it done by tomorrow sometime.

I'll put it in a zip file and supply a link to the download.

Hi 3dwizzard,

The blue lines show open edges.

One way to align the edges:-

Here I have got a cylinder that is not connected down the center line, with gaps between the 2 parts. (It is one object/mesh).



Select all vertex (or edges) that make up the center line of the mesh



Because the objects center line is at world X/Z zero (your skirt will be at the same location, as the character mesh would of been imported to that location). Set the manipulator(pivot) to World orientation/Pivot position and set to "scale" manipulator.



In the main view, select the X axis on the manipulator and drag to zero



If you want then to copy one side to the other to repair the mesh, you can use the shortcut keys for symmetry. But first make sure symmetry is set up correctly in "Edit-> Options-> Shortcut Symmetry Options->", which looking at the pic you posted, would be "X axis", and select "Symmetry enabled"

You can then press "Ctrl+W" which will remove (looking from front view) the right hand side( positive in X) of the mesh, copy/mirror the left side(negative in X) and weld them together.
Or,
Press "Ctrl+Q" which will remove the left hand side(negative in X) of the mesh, copy/mirror the right side(positive in X) and weld them together.

Hope that helps.

Wow, that's different. Not quite what I'm used to. But it works.  :)




I wanted to try it in Poser, to see how it drapes. But I can't seem to get rid of these eyes and mouth.
I tried to delete them in VW, and couldn't. Any ideas?

I got it. Didn't realize there was that many vertices in eyes and teeth.

If you have the character mesh still in scene, and want to just export the skirt, select just the skirt and "File-> Save selected".

Didn't even see that, thank you.  :)

I thought I would update this.

I had some trouble trying to get the spline's to clothify.
Never could get it. They seem like wires.

When I tried it with the straps. It never stopped calculating.
I started calculating before I went to bed. When I woke up the next morning,
it was still calculating. I don't know why.
Maybe Posers cloth room, got confused by Retopo?
I don't know. I tried it a few times, and it was always the same thing.
It just seemed to calculate for ever.

I did a couple versions, and the strapless version worked best.
Here is a render:

What is this calculation thing you talked about? Does it happen in VoidWorld or Poser?

Hi 3dwizzard,

How did you get the splines into poser?
I believe Poser will only "clothify"(is that an actual word lol) polygons.

When exporting the dress from Nvil, make sure you only export the dress, select the dress and use "Save selected"

I do not use poser much, and never used the cloth sim (I should have a play). Maybe you have bad geometry? or maybe a problem with collision detection?
What version of poser are you using?

It is in Poser, it is to calculate dynamic cloth. I made this skirt with Void World.
I was going to get Silo, and somebody suggested to me to try this.
I'm glad I did. I like it. I just need to get used to a few things.

I just imported it, into Poser through: File/Import/Wavefont OBJ....
Didn't have any problems. It imported real nice.

Now that you mention it. I do recall something like that.
It's been so long, that I had to learn how to do a simulation all over again.

Save Selected, that might be it. I'll have to try that.

I wondered that myself. Sometimes I think that's a word that Crious Lab, made up.
But it is the second step in  the cloth simulation:

Bad geometry, that could be possible. I could've deleted something that I shouldn't have.
But I don't think it was the collision detection.
I got that straightened out now.

I'm using p6. I have Poser Pro. But I have a lot of scripts that are P6 specific.

PS. Sorry so long between posts, been working a lot in the garden.

3dwizzard, VoidWorld does not export splines to obj file.

I guess you may have exported the reference model with the cloth and Poser treat them all as cloth mesh. If this is the case, you can imagine how big the amount of calculation it could be. One way to check it out is to check your obj file size.

Hi IStonia,
                Thanks for pointing that out. I looked at the polygon count
on the strapless skirt. It was 720.
Then I looked at the straped skirt, and it was 2200 and something. Big difference.
I looked closer at it, and the splines wasn't even there. The problem was,
the straps themselves. I tried to get too fancy. Way too many polygons.
There was a lot of triangles to.
I think it would be easiest, to start with the strapless skirt. And add straps.
Many thanks.  :)

720 and 2200 are not big different to me. Maybe the problem lies in the straps geometry. You mentioned you have triangles there. That could be a possible reason. The other thing I wonder is that the shape of the straps may not suitable for cloth similating in Poser. You can try a strap with jut a few polygons and see how it may happen in Poser. Another test you can do is just try a mesh with straps only and no skirt.
