[Plugin] UV Toolkit

HASIAH

Hello Thom,

Please I have been trying to install UV Toolkit but it is not showing in my google sketchup pro 8. I downloaded the softaware...google sketchup 8>plugins but it still not showing in sketchup when I start.

@Hasiah

Have you also downloaded/installed the TT_Lib2 as instructed on this tool's download page...
Have you definitely installed everything with the exact 'footprint' for files and subfolders, as also explained on that page?

thomthom

Ditto what the tiger said.

i will post the model shortly when i have a little freetime during writing my bachelor thesis

Carloh

i gave it another try at my desktop pc with windows 7 and it worked! somehow it has to be something with OS X then....

thomthom

hm... should be working fine on both system though...

I am not the man of words,

Would it make sense to create an arched texture and map it just flat on to your arch instead?

Hello,

I am having an issue using his plug in
I open sketch up and it reads:

"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"

I think I put everything in the right place but its not working. I am using windows 7 can you help?

TIG

You have not installed the supporting 'Lib' as directed on the plugins main page...
If you think you have installed it and there are still errors, then check your Plugins folder's security permissions are set to FULL and retry the installation...
There are many other threads covering security permissions etc in very great detail...

I have a 3d model which has colours but no textures... at least, I can't see any texture upon exporting it in Collada (.dae) format.
But I need a texture file to convert to VRML and to be able to upload file to Shapeways.
Can I use this plugin to obtain a texture map from my colors?
If not, how can I accomplish this task?

I'm getting the following error

I posted a similar response to you in another thread.
Do not copy plugins files/libs from an earlier SketchUp version.
Install the newest available ones - available from the PluginStore - they have been updated to suit v2014 !

Hi, I'm using UV toolkit with FredoScale for game modelling.
I've noticed that when I export the model(to dae), I get one texture for each quad face. I'm making a city model and this results in thousands of textures... Is this just how the plugin works or is it something I can do about it?
Edit: Never mind, Just found out that the faces has to be triangels...

If I open a model made with skp 2013 and an earlier version of UV toolkit(and TT_lib) and try to edit the UV-mapping in Skp 2015 with the most recent UV-toolkit and TT lib , will the UV-mapping get messed up?

thomthom

No - should act the same. Are you seeing otherwise?

Hi Thom,

I was playing with UV Toolkit on a model from warehouse:
https://3dwarehouse.sketchup.com/model.html?id=1c056259336d676cf69f18f886bbb404

I tried to copy come textures from one face to another and get next error:

Surfaces I'm talking about are rectangles, below arches Problematic surfaces

I've inspected them a bit, it is definitely rectangle, and seems problem is that for UVQ coordinates we get 2 pairs of identical coordinates.

` face=Sketchup.active_model.selection[0]
face.vertices.each{|v| puts v.position}
(-81.244783m, 48.236298m, 29.144603m)
(-81.244783m, 48.236298m, 25.126711m)
(-78.64126m, 46.296916m, 25.126711m)
(-78.64126m, 46.296916m, 29.144603m)

tw=Sketchup.create_texture_writer
uvh = face.get_UVHelper( true, false, tw )
uvq = face.vertices.collect { |v|
uvh.get_front_UVQ( v.position )}
[Point3d(-0.77926, 0.615652, 1.07232), Point3d(-0.77926, 0.615652, 1.07232), Point3d(-0.770337, 0.611328, 1.07188), Point3d(-0.770337, 0.611328, 1.07188)]`

Is there some solution for surfaces with such coordinates?

I've tried slight change in plugin code: removing of duplicates (and their corresponding vertices coordinates) and then position_material -> no error, but final texture not positioned as original one.

Thanks in advance,
Marija

Hm... I think this relate to projected textures. The API doesn't have good support for that type of mapping.

You are right. I've checked and these are projected textures.
I know not much useful things in API on mapping of projected textures.

Do you think there is some possibility to 'extract' that info and use it for pasting. Something with get_texture_projection() and set_texture_projection().

Marija

thomthom

get_texture_projection and set_texture_projection was an attempt to add support for that. It was added close to a release a while back. Though it didn't really fully solve things. (and should probably be deprecated.) As things are right now there aren't any good info to go by.

I noted when you save UVs data and then you save the .skp file the size of the file increases notably, is there any way to cleanup that data after it has been used?
It would be fantastic to add a feature to clean the data.

Example: UVs data of 6000 faces, the file increases about 4mg, if you have saved the UVs of various objects the increment can be immense.
