Roof tile image problem

[Shedman45]

I’ve lost the tiling pattern on the hipped portion of the roof in the attached model. It is there when zoomed in really tight. I though it would just be a question of identifying the material from the adjacent roof and reapplying it, but no. Is there any way of restoring this to match the adjacent areas?

You’ve got a number of issues. You’ve applied the roof tile material to the back faces. Entity Info shows that when you select the faces inside the group.

You also have exposed back faces which should be corrected.

You also have the material applied to the group container which isn’t really the right way to manage the texture.

The texture has been incorrectly scaled on those faces.

I removed all back face materials and moved all of the materials on the object wrappers to the faces inside. Then I edited the two roof objects with the incorrectly scaled textures, removed the materials by applying the Default material to them, and then repainted those faces by sampling from the roof section in the rear with the same face alignment.

BTW, I notice you are using tags incorrectly. Untagged should remain active at all times.

ALL edges and faces should be created and remain untagged. Only groups and components should be given tags. Here’s the result of fixing that in your model. My guess is the rest of the model needs the same fixing.

And the fixed roof.

Thank you for this in depth explanation. I’m not sure how one gets to know the right way to do all these things. Is there a training resource I could look in to ?

You’re welcome. A lot of it is just experience. You could go through the instructional materials at learn.sketchup.com I don’t know of anytraining resources that specifically deal with the problem in your model, though.

A few tips might help.

Ensure proper face orientation in 3D objects. There should be no exposed back faces.
In the majority of cases you should apply textures to faces, not groups and components. That will give you better control over how the textures are displayed.

Unrelated to textures: Make sure you are using tags correctly.

BTW, please update your forum profile. The model you shared was created in SketchUp 2025 not 2024. Also please put the model of your graphics card in your profile. “motherboard” doesn’t answer that question.
