Bending a textured face

Chris
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.

If this object is bending only one direction, you should not use projected material on it but simply wrap it around the curve.
Could you please elaborate? I've tried so many things with this I'm not sure if this is one of them.

Where's that model?

If you mean the jpg for the mat, here it is

Great! Now, could you please explain the process of what you did?
-
Some pictures. After sampling / painting in picture 5, repeat the steps for the rest of the facets. It takes less than a minute. The point is that now you are not projecting but wrapping the material around that curve by positioning it.
(Sorry, previously I attached a wrong screenshot) -
Excellent Csaba.

Finally! I won't have to track mud and snow into my nice clean Goat. Much appreciated!

Good thing in Fredo's plugin that it keeps the sizes of all the facets and the rest of the model as a whole (so the image will fit exactly as it does on the flat one). Bad thing is that it screws up UV mapping even when I position the texture before subdividing (i.e. all the texture pieces should still be positioned - or not? I will have to check).
Edit; even if I "pre-position" the texture on each facet first, the plugin screws everything up. I wonder if Fredo could do something with it.
