It seems if it’s forgotten to behave like a texture instead of an image. Was the jpeg inserted as image, first?
How did you applied it to the other faces? was it grouped already, or did you group it afterwards?
Can you upload an example file where this is happening?
It might be related to this bug:
Here’s how to reproduce:
Open a new (blanc) file.
Import an image and draw an edge.
Group both entities.
Draw a face, choose the paintbucket tool.
Sample from the image Group and apply to the new drawn face.
Check the 'In Model collection ’ of the Materials panel.
Set Face style to ‘Hidden Line’
Textures don’t show when on hidden line. As you can see the texture, it is either an image or it’s color by tag.
Discovered something interesting when testing this. If you have a texture with some transparency, the transparency is kept when in hidden line. That would let you do X-ray like effects in selected areas.
Like clipping, this might have some practical applications…
It must be something like the same as using an image in a group as a texture. But that doesn’t show up in the Materials browser, as it does in the first screenshot in this thread.
That breeze block texture is indeed behaving very oddly.
Interesting, On Mac I am able to load any texture I have access to in the material picker, including ones saved in custom folders but not in the current model. This opens the door for some fantastic options in semi-transparent texturing while in Hidden Line. Also interesting is that the applied tag textures do not appear in the 'in-model" list but do persist through a purge and a save.
