exporting dozens of skewed materials

Did you try triangulating the SketchUp mesh prior to export?

Yes, I have both the 'triangulate faces' option selected in COLLADA export, as well as having tried to triangulate the faces manually using SketchUV and FredoTools. All produce the same results.

Hello,

Yes, necro-ing a very old thread, I understand.

I am wanting to either use this script in Sketchup 2020 or find a tool that will do this for me. I have a model that I must export to .dae format that is exporting dozens of skewed materials. This material is essentially a painted line on a roadway that I have used ThruPaint to map onto lines following unique paths.

Trying to use this script in SU2020 throws multiple syntax errors. Is there anything that I can do here?

Thanks!

It is a very old thread !
I've fixed the basic syntax errors and added modules etc.
It works in v2024 [should be OK in v2020] - but I'm unsure of its efficacy...

Haha yes!! This seems to work, at least at first glance. Just one texture exported. Thank you so much! I will report back if I have any other issues with it.

I tried to disable the option to triangulate faces. It made no difference whether my faces were triangulated manually or not.

I have attached just the portion of the file that is giving me problems.

Hi all,

I am attempting to model some very low-poly cars for use as scenery objects for flight simulator.

Issue #1:

Each car is an individual component in Sketchup for ease of copying and modifying. When entering the component and then exiting the component, the texture mapping of any Projected textures in the component distorts. This distortion changes every time the component is entered and then exited, as visualized below:

Correct mapping, already inside component:

Upon exiting component:

Upon re-entering (the space around the cars on my texture sheet is black):

Issue #2 (possibly related):

Upon exporting said vehicle in any format, the texture mapping remains distorted, even if it appears correct in Sketchup, as visualized below:

Front and back of car, prior to export (component exploded so that texture mapping will appear correctly):

After exporting and importing into ModelConverterX (flight sim model conversion program), note the difference in position of the front bumper area and the distorted back textures:

This distortion, shifting and export weirdness is happening to all of the cars I have made thus far and I cannot for the life of me understand why.

Issue #3 (also possibly related):

Any time the viewport (camera) is moved around in Sketchup, the textures on the cars (and only the cars) appear to vibrate. Additionally, these textures appear quite 'fuzzy' in a way that all of my other textures do not. See below:
