help with error when exporting

[2kemon]

Hi again guys
I'm sorry to bother you again, but it's been a while, since I last used indigo. So I'm kinda rusty. Can you help me with this error message?

The <uv_set> tag exposed in the scene definition contains a name for an UV set that was not found in the geometry itself. One amongst the two must be corrected to match the other, you choose wich, and how. I think Indigo would throw another error if no uvset were declared at all in the geometry, so that should be easily fixed as I mentioned. I don't know the correct workflow to avoid this in the exporter you are using, neither if the user is guilty in this case

[2kemon]

I'm sure it's a user error, CTZn
But from what I understand, you're saying, that I don't have any geometri with "default material"?

Because, without any technical knowledge of the problem, I guessed, that it might have something to do with sketchup having a default material, when I started the model, but then replaced the default material. My not-so-clever fix was to paint a box with a material and call it 'default'. But that didn't help.
It's a relatively simple scene, but I would still hate to remodel the whole thing.

Again, no SKetchup specific answers from me

Generally speaking, material and uvset names can be independent without a problem, they are two different things. What I can't tell is (1) wether the geometry has an uvset (I'm too lazy'n'busy to check), and (2) how you can edit its name in Sketchup.

The uvset will tell how the textures are dispatched onto a surface, the shader will eventually use this "distribution" to get its paramters values from the texture at the specified spot. UVset are part of the definition of the geometry, while materials are attached to that whole thing.

Now to SKIndigo users !?

What I can't tell is (1) wether the geometry has an uvset (I'm too lazy'n'busy to check)

I confirm this happen when a mesh has no uvset at all.

Hi 2kemon!
In my personal experience, that kind of error message pops up when you try to render a simple-color material with an additional map applied.
I mean, a simple white plastic (no diffuse texture) with a bump map, for example.

Generally, that problem is fixed by following the UVmapping tutorial Whaat provided along with his updated versions of SkIndigo.

You loaded a a material that was expecting a uv set, but you didn't give it one it sounds like. This isn't going to sound very encouraging, but your best bet would be to delete the material and start over again. This is problem with the new skindigo material loading system.

pibuz, you're da man!!!

That was the problem, so now It's working, and I'll just finetune the scene, and then I'll post it on the forum, so people can use it for tests. Just like you did at SCF.

You're welcome
