Material Not Applying Properly to Mesh?

[Dotty92]

Hey guys,

I am trying to apply a material to a single mesh. The material has a bitmap texture for diffuse and an opacity map.
The problem: half of the mesh has the material applied correctly - but the other half tiles the material.
I could understand if these were two separate meshes but it is one single mesh.
I've tried playing with the texture mapping but no luck.

If anyone has any suggestions, I would be very grateful!

Hello,

You can use the Rhino UV Editor to produce custom mapping by tracing the vertices of each stalk onto the designated map. V-Ray will process the object mapping the same way it is displayed in the Rhino viewport. In other words, the issue at hand is solely on Rhino's side.
For more info, check http://docs.mcneel.com/rhino/6/help/en-us/index.htm or take a look at tutorials such as https://vimeo.com/268449998 .

Kind regards,
Peter
