UV editor Apply changes

Dear Rhino Whisperers,

I’ve done the texture mapping tutorials with the chair and secateurs so many times I now know the script better than the Lord’s Prayer. Perhaps it would help to learn the Lord’s Prayer.

I’m trying to unwrap this surface (a steamed oak frame) and apply the material to it in UV editor. It all looks very nice and sexy, then when I _apply it all goes mushy and not at all scaled as the preview indicated.

I think I’m using Custom Object correctly and the right channel.

Although I’m playing in WIP V7, I was having similar issues in V6. Do I have an antiquated brain trying to operate modern technology?

Any help greatly appreciated.

make sure the unwrapped mesh stays within the borders of the texture. To me it looks that two corners stick out slightly on two sides in the image you posted

something else: it is easier to unwrap that part before adding fillets. Attached an example, where one part was filleted after the unwrap: mapping stays intact.unwrapped_rhino7.3dm (2.0 MB)

Thanks @Gijs,

I wish it were that. I just tried it and unfortunately it didn’t help.

Do you think it could be the chamfers making the Unwrap problematic?

beautiful endgrain. Is that a native Rhino teak?

better share the file in question, then we can have a look what’s wrong. Does my example display nicely at your end?

its a simple texture (I think it is not based of real wood), I think it is embedded in the file I sent.

Yes it does @Gijs,

here’s the model

frame_model.3dm (1.8 MB)

it’s not your uv unwrapping, but the material that causes this. The mapping repeat for color texture is set to 0.01 in both directions. Set this back to 1 and you will see your woodgrain back.

I see. I’ll try that. I’ve just re-saved and opened in V6 and it works fine there. I’ll try your technique. Thanks @Gijs

There appears to be a little V7 problem using the curser to change view during UV edit. It’s not happening in V6
