[Plugin] UV Toolkit

thomthom

Hi,

I used the plugin to use the "Frontface Material to Backface", and it worked fine, but when I check for errors in SU, it says: "The front or back texture coordinates for CFaceTextureCoords (48) is not valid" for every face and when I click fix, it reverts to the way it was before using the plugin (no textures on the backfaces).

Any ideas? Or is this normal?

Thanks.

Huh! That's odd. Don't know what's going on here. Never seen that before - and the model looks to be fine. I'll have to investigate.

Is there a very tiny facet that returns invalid coordinates, that are regarded as the same because of the 'rounding' of its very close vertex-points ?

I just had a perhaps somewhat similar issue with my Octane Exporter [on their forum]... Someone has made a very small object that would have had overly tiny facets when created, if they hadn't scaled it up to process and then back down when done - the small facets can exists, it's just making them that's the issue. So far so good... now they exported it to OBJ format for use in Octane and there were tiny holes in the object when it rendered. Octane requires the OBJ to be in 'm' and have triangulated faces. In processing the meshes my tool uses the API methods to triangulate the mesh's faces. I now think that what was happening was that the triangulation of some tiny quad faces resulted in two triangulated facets that are so small that they have two vertices that 'round' to be at the 'same point' [the OBJ format is set to 'm' 6 d.p.] - therefore that new facet can't exist as its only a 'line' at best, and the two parts can then be missed, out leaving a small quad shaped hole when the object is reformed from the OBJ data...
This could of course also mess with the tiny face's texture mapping ?

thomthom

It's a 1:1 scale building with textures...

TIG

BUT might it still not have a very tiny textured facet somewhere that is thereby tripping things up ?

thomthom

I'm not finding any small faces...

Btw vanman - your SketchUp file is 8 MB because the texture you used is 8MB JPG - 4096x4096 pixels. The very max SketchUp will display is 2048x2048 if you enable large textures.

TIG

I'm out of ideas then

vanman

Ok,

Thanks for looking into it. I'll just deal with it on a model by model basis.
I'll reduce the image size, I didn't know about the SU max texture size.

thomthom

I've not had time to dig deep into this. I've a wee bit busy for the time being. Trying to get some stuff ready for Basecamp.

usen

Thanks.

mannomann

Hi,
sorry for that question: I put the plugin into the plugin folder. But no plugin is in SU. What is wrong?
J.
Cannot read 23 pages for installing problems. Tried to use the search, but no results for that problem.

Just read the first post and make sure you follow the instructions carefully. Have you also installed the TT_Lib library for instance?

mannomann

Didn´t and don´t find installing instructions. And in the downloaded file I also do not see the TT_lib library.

mannomann

Ok - thank you.
The missing TT_Lib was the problem.
Best regards

Hi,
I already installed the TT_UV_Toolkit at my Laptop at home.
Here on my businesss PC I don´t know anymore and can´t remember where to put the TT_Lib???!!!
And I still do not find a installing instructions for that.
Would somebody please be so kind and show me the install passage?
Or any hint?
Thanks in advance MM

OK - found it.

You sure these UV things work on Sketchup 8? I've been getting a lot of errors, namely:

Error Loading File C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/TT_UV_Toolkit/loader.rb
no such file to load -- TT_Lib2/core.rbError Loading File tt_uv_toolkit_2.rb
no such file to load -- TT_Lib2/core.rb

And before you ask, creating the TT_Lib2 folder and placing core.rb in it did not work well. And it's not really my job to try and "hack" plugins so they work.

It's also not my job to create plugins. I create tools to do my job and I release them for the public to use as is. The least you can do is take a moment to read the instructions of the free tool you're trying to use.

If you go back you will see at the bottom of the thread the footprint of where the files should be. You should not manually create a TT_Lib2 folder and move the core.rb file from UV Toolkit into it. You should install the required TT_Lib2 support library as link right above the UV Toolkit download button, labeled Requirements. It's all there, at a glance. In no way are you supposed to "hack" anything!

If you have trouble installing plugins you can use this utility: http://sketchucation.com/forums/viewtopic.php?f=323&t=42315&p=375454#p375454
It let you install RBZ and ZIP packages. It's an RBZ package itself so follow the instructions in the thread (lots of screenshots) on how to use the Install Extension feature in SketchUp.

For a complete breakdown on installing plugins: http://www.thomthom.net/thoughts/2012/01/installing-plugins-for-google-sketchup/

(However, installing them to the correct location wasn't the issue here, it was because you didn't read the instructions!)

I've got constant 'Don't panic!' pop-up that 'fixes' the error after applying 'front face mat to back face' (as a result backfaces are messed). Could you take a look at the attachment?

I got a warning when I first opened the model. When I said fix problems that reset the backside textures. But when I ran the plugin again, front side to backside and used the Fix Problems button - I got no errors.

rv1974

it will get back sporadically. Any clue what could be the reason?

thomthom

No. And without being able to reproduce it it's even harder. :s
