Bending a textured face
-
Thanks for the suggestions, but here's the thing - I'm gonna be working with textures a lot, and if what I need to do can be done, I really, really need to know how. It will make my life so much simpler, and will greatly decrease the frustration factor I'm having with SU. I've posted the question on the Shape Bender forum, maybe somebody there has experienced the same thing. Surely someone has. Surely. I know, "Don't call me Shirley"

Alright Shirley.
Here's your floor mat with Shape Bender. Absolutely no tweaking of the material was done.
I brought the image in as an image, traced round it and then exploded the image so it became a material. I turned the flat mat up on edge so I could use Shape Bender, drew the appropriate lines and ran the plugin in. Looks to me as if the material went around the bend well enough.

While you did get Shape Bender to work, it didn't solve the original problem I had. Look at where the red Pontiac logo is now compared to where it was on the original. As I said before, it's like the texture is being projected down onto the face instead of being on the face. That's the problem I need solved.
I do need to figure out how to use Shape Bender, I know it will be the answer when I need to do more complicated bending. But at least now I know that it's not the answer to this particular problem. Same results, exactly. And I must say I'm glad to know that, because SB involves much more time and effort than RB.
I still can't believe that other people haven't noticed this problem when bending a shape with a texture on it. Unless it's only when my shapes are bent
As Moses once said (at least in the movie), "Why me Lord?"
-
When you modify geometry in SU, the texture does not get modified (unfortunately). So yes, other people also notice things like this but we cannot do anything about it. So the general rule is to model first and texture next.
-
I don't see the pontiac logo moved at all. Did it?
-
Yeah it did. Unfortunately
I only used the logo as a reference, as you can see, everything moved.
-
Well, then it shouldn´t be "bending a textured face", but the other way around
-
It actually did cut a bunch off of the top. I did it this morning around 4 am before my coffee had kicked in so I didn't notice it. I measured out the line with the bend in it so it is the same length as the flat mat. I suppose the material is the projected length.
As Csaba says, there's probably nothing that can be done about it with the way SU currently handles materials. Perhaps if things like this are really important, it would make sense to look at some other application either for applying the materials or possibly for doing the whole drawing. Although all sorts of folks are using SketchUp for things for which it wasn't originally designed, including myself, and making it work quite well, I am sure there are some jobs that are still better left to other programs.

If this object is bending only one direction, you should not use projected material on it but simply wrap it around the curve.
-
Any chance of a plugin for this?
-
Something to glue the texture to the face or object so that it is affected the same way. Or maybe turn the texture into a face. As you can see, I know not of what I speak
You could call it "Texture Superglue"
-
Thomthom is working on some kind of UV plugin. Maybe that will be able to do it. Also, I have seen sneak previews of Whaat's new Subdivide and smooth plugin.

If you made the texture unique on each face of the mat, it might work then?

The mat only has one face. If you're talking about dividing it into parts before bending it and making each of them unique, I thought of that, but wouldn't that increase the number of textures? I don't know enuf about this stuff to even be saying anything, but I am trying to keep my textures to a minimum to keep my file size down.
Probably not what you meant anyhow.
I'll shut up now and go away
-
That is exactly what I meant. It might be the only way to do it? I don't know. Where's Thom?

Hi Chris, that shouldn't be necessary in the way that you get multiple textures.
Only one should do.
If you do this manually it's an easy proces towards the result. See attached file.
(Although I don't suppose hellnbak is looking for laborious modelling).I don't know enough about your plugin but when done manually the texture I used is fixed to the original flat mat geometry. Once you split up the mat and rotate mat "segments" successively, the texture stays as it should. This could be done the same way in a script can't it?

Even if I am not deliberately looking for it, I do not mind doing it when I know I cannot achieve it otherwise and the result is worth the laborious way. Wrapping a texture around a curved face should not take longer (even if you go facet by facet) than writing a forum post.
This window below is on a curved wall (a basilica apse), arched and all the edges are rounded. So there was no other way than manually doing it.
(By the way, in this model, all the edges are rounded everywhere as you can see from the buttress, too, so when I made the textures, I even counted the pixels how they would wrap around to make a seamless tiling when they reach around pillars and such - tell me about labour!
)

The leather textures were applied to the curved shape with hidden geometry showing and clicking the paint texture tool at each change of plane. Rendered in Twilight Render using Metropolis Light Transport with Bidirectional Path Tracing. This is one small part of my project without end.

Could you please elaborate? I've tried so many things with this I'm not sure if this is one of them.
