Just wanted to show off the camera straps I managed to drape in VWD : )

Man, I just loooooove VWD!

Made these by simply making a plane primitive in DAZ Studio, then cutting off most if it using the geometry editor, leaving a long narrow strip of UV'd quads.

This ribbon was then dynamically draped in VWD around the posed figure, connecting it on both sides to the eyelets of the camera, after pulling it tight.

Back in DAZ Studio I cut off excess quads on each end, and exported it to a mesh editor to give the single sided ribbon some thickness.

Then back in DAZ Studio I subdivided it, and then made the other one just the same way.

Just look at the way those straps follow the contours of that vest (also shaped around G2F's chest using VWD), couldn't think of another way to do that.

Hello Erik,

Thank you for this very interesting example. You are right, the positioning of the straps are really perfect.

May I ask you to send your images in the VWD gallery. They always give great examples of what it is possible to do with the program.

I added the Inversion of normals in the format in the "Collision parameters" tab. I hope this will be useful.

Have a great day.

 Gérald

Thanks Gérald, both for appreciating my experiments AND adding useful features to VWD : )

Of course I will add some of my pictures to the VWD gallery, anything I can do to 'spread the word'.

Here's another example of the method I used for the camera straps.

It can be used for hydraulic or electrical conduits, or cables, or hair ornaments, whatever.

Something like this would have taken me hours to do 'the old way', now using VWD it just takes a few minutes!

Cheers!

Erik

Here's what you could do with that kind of VWD stuff (just for fun!) VWD hoses-conduits test_03.jpg

Great experiences

"exported it to a mesh editor to give the single sided ribbon some thickness". What tool do you use? Would it be possible to give some thickness to clothes without loosing the UV map of the existing polygons? I found that "cigaret paper thin clothes" unrealistic:

here is an example

Hi Smaker1,

I use Rhino-3D, but might as well use ZBrush or 3dCoat for this.

In Rhino its a convenient two-minute job, even though it isn't a true mesh modeller like the other two.

Here's a screenshot from DAZ Studio, on the left the original OptiTex Doctor Coat, on the right a thickened version (1mm). You can see clearly that the UV's have been retained, inside and out.

You can also split the inner and outer layer, so you can use a different texture for the lining of the garment.

Cheers!

Erik

Here's a close up of the mesh structure with two levels of Loop SubDivision in DAZ Studio.

For SubDivision to work without breaking up at the edges, the mesh must be fully welded after thickening, also a trivial task in Rhino.

Amazing! I'm not a modeler and I must invest more time as I have Z-brush. I know I only use 0.05% of the functionnalities but these 0.05 are already great help! I'll try to find the same process in Z-brush

Thanks for your time!

Hello Eric and Stef,

I am also a fan of Rhino3D. It is, for me, certainly, the greatest modeling program.

Thank you for all these examples.

Gérald

You're very very welcome : )

Here's another example of a complex bundle of hoses or cables that was a joy to create using VWD.
