Fredo,

Great plugin as always.

I hate to be the first one with a troubleshooting question but it seems to take a long time loading and gets stuck or stops at 75%.

Do you have custom materials in your Sketchup environment?

Gus R · 30 Sept 2022, 15:17

Yes.

Gus R · 30 Sept 2022, 15:37

My materials are located in C:\ProgramData\SketchUp\SketchUp 2022\SketchUp. I copied those over to ...Users...\AppData... and disabled (just a random rename) the one under ProgramData and it loads. I undid the rename and it goes back to not being able to load. So it seems to be looking for materials under the Users folders. So it can read my skms but can't find them under the ProgramData directory.

Are materials/skms path dependent?

fredo6 · 30 Sept 2022, 15:47

I sent you a PM with a version of LibFredo6 with traces.

Could you put back your materials as there were when you got the error and see in the Ruby console which material(s) is faulty.

Gus R · 30 Sept 2022, 15:58

That ruby wouldn't install. Tried twice. Sent you a PM with the ruby errors on the install.

gullfo · 30 Sept 2022, 16:03

not sure where the IMAGE_RickOBrien folder is or how to change it

also same error with the materials path. it's says the roaming profile path is the default even though the setting in SU is the ProgramData path.

It works but only when my materials are under ...AppData\Roaming\SketchUp\SketchUp 2022\SketchUp and not under C:\ProgramData.

The ImageRichOBrien is simply an alternate set of icons and cursors. After choosing it, you need to restart Sketchup

Do you mean that this is what you set in the Preferences dialog, Filestab, Materials?

Normally Sketchup loads all materials in ProgramData at startup. The directory you indicate for Materials in the Preference dialog is simply the folder that will open first when you load materials from the Sketchup material browser.

This is where you should put your custom materials. However, you need to manually load them from the Sketchup Material Browser once.

The ProgramData directory is only for the native Sketchup materials and can be overriden at Sketchup installation.

It's an alternate icon set that you check on and restart SketchUp to activate. It is located here...

Fredo,

The top bar or title bar in the window shows up for a split second then collapses making it difficult or impossible to move the window. There's just a sliver showing up and you have to precisely click on that.

In principle you can click within the background of the window (for instance right of the tabs) and drag the window.

Fredo, is it possible to have ability to see custom material collections I alreadyhave in standard material browser? Thanks

If you have directories with skm files (or subfolders containing skm files), you can integrate these materials to the browser, by defining

either create a top folder as the top directory where you have your custom collections. The directory will appear at the top of the Materials hierarchy. You will be prompted to give it a friendly name.
or put your custom materials and subfolder in the preferred Material Directory, which is C:\Users<username>\AppData\Roaming\SketchUp\SketchUp 2022\SketchUp\Material. These materials (and subfolders) will automatically load. I think it is the same for the native Sketchup Material Browser. The menu entry Open Preferred Material Directory open this directory.

Click on the menu of the browser for the two options:

Is it possible to get the UV without distortion on an object like this with Thrupaint? It's a pretty simple shape and I attached the skp file.

Thrupaint Test.skp

fredo6 · 7 Oct 2022, 07:27

A cube, although simple, cannot have all its faces painted in continuity. This is just a matter of geometry.

If you wish control on where to pu the seams, then you need a texture wrapping tool (like WrapR), or a manual approach.

Also, in the case of a cube, you may want to first paint the cube, and then use FredoCorner. This gives a better management of the zones of non-continuity.

Thanks Fredo. UV mapping in Sketchup is difficult sometimes even for simple forms.

I have an issue where Thrupaint is invoked when I double click on Thea Render for Sketchup materials. It oddly happens on the second attempt to change the Thea material. If I close down Thrupaint I then can't change the Thea materials unless Thrupaint is turned on. The same thing happens with Sketchup materials after this happens. The paint bucket stops working. I can then only paint an object unless Thrupaint is turned on.

Gus R · 7 Oct 2022, 07:54

Continuing with the Thea Render materials problem the sequence goes like this:

Double click Thea material and apply material to object.
Double click again to change material and Thrupaint turns on.
Paint with Thea material using Thrupaint and it changes.
Then when I try to paint the object using the Paint Bucket tool it does not change.
After that I can only change the material through Thrupaint.

I can't change the material in a grouped object unless I use Thrupaint. This only happens in groups. I haven't tried a component yet. Either way I go back to the Thea materials and Thrupaint gets turned on at a second material change.
