Mapping in Vray

[Ayajiv]

Hi there!

A beginner question:
I made a chair in Rhino/Tsplines and turned it back to Rhino before Vray rendering.
UV mapping seems to go all over and the texture mapping is (propably?) not so comprehensive.

The texture should go along the slightly curved leg(s) in all four sides.
How to do that?

Thank's for help!

That not a Vray problem. You need an unwrapper/unfolder software that unwrap the UV coordinates of the underlaying mesh. But I would ask the T-Spline team which workflow is recommended for texturing.

[Ayajiv]

Yes, I know it's not a Vray problem. More like a beginner problem
Just want to know how to do this type of work.

Thank's, Micha!

Ps. which workflow is normally used in this type of work?

Hi
Tsplines have a new UV Editing tool for mapping on TS 3.3. I tested it an work good. They are going to have a webinar today to show the new features.

Holy shit!
Thank's for telling me that!!!

Here I go this way: export the model as mesh (best meshed per MoI or exported per Rhino5 and complete welded) and open it in Unfold3D. There I set the UV cuts and unfold it.

[Ayajiv]

What is Unfold3D?
A program?
...or a way to open a file?

[Micha_cg]

It's a software.

Here you can see a Tspline example:

an other example attached - parts of a simple train seat there I add some constrains to get straight sections. Left the model with test mapping and right the UV coordinates. I use the software quite often to get textures on organic formed seats. Best results you get with clean meshes like known from moi3d(.com).

PS: I bought it some years before with a christmas special discount. If you are interested, maybe you wait a little.

[Ayajiv]

Ok.
I'm a bit surprised that these things can't be done among Rhino/T-splines/Vray(?).
Have to look at the new UV Editing tool for mapping in the new T-splines 3.3. Maybe some of the answers can be found there(?).

Thank's again, Micha!

Ps. nice work on your pages...

[Micha_cg]

A good unwrapper is not a simple tool and so it's no wonder, that the T-spline tool seems to be a basic tool only. I give it a short test. A more advanced tool allow to add constrains and to adjust the mesh for your need.

Rhino 5 also have a unwrap tool. It is not as good as Unfold 3D but could work for you. The tools in under the UV Mapping.

Ok, thank's!

By the way, does the Rhino5 beta run over Rhino4, or will they be two separate programs on my computer?

They are separate software. You can have Rhino 4 and Rhino 5 in the same computer.

... and if the new VfR beta is out you can install it for Rhino 5 64bit (if your OS is 64bit) and your old VfR stay ready for projects per Rhino 4. So can avoid the risk to work with a beta.
