uv transfer problem

[zhenka22]

Hi all

Since my previous post i have become a lot more comfortable with uv mapping. The problem now is that for some reason the uv transfer function is playing up in my project.

I have a number of identical models. For some, the uv transfer works without any issues, whilst for others the uvs don't not transfer at all. If the geometry of the 2 objects is identical, what possible reasons could there be for this problem? The models seem identical in terms of geometry and attributes, no history etc...

Thanks guys

Whilst looking further into this problem, I have attached a checkered texture to the geometries in question. It turns out that even with the objects for which the uv transfer worked, the texture comes up extremely warped, although in the texture editure everything looks fine!

It seems that only the objects that were originally mapped come out fine. Am i missing something here?

Any help would be great! :frown:

Even if your models look the same, if they have different vertex numbering, the UV transfer will break. One scenario where your vertex number can change is when you take the mesh, delete one half and mirror and merge the geometry. The meshes may look identical but UV transfer doesn't see it that way
Did you do a render with your checkered texture? If the render isn't warped then you're okay.

I see, that must be the problem...I guess I assumed that by deleting history that issue would go away... Is there any way to get around this without remapping those objects individually?

Thanks Sunder
