Hi Lara,
The original one I posted was purely just the blend tool.
Being as the 4 blends need a common touch point I created a temporary surface in this position to make the first blend.
You can then blend to the blends themselves diagonally after this.
The modified version I created a small gap so they where not touching also I modified your shape a little as it had a tight turn at far end.
Hope this helps.
Barry

Thx.
You are right PaQ. I must say...my uv-texturing skills are very poor.
May you tell me your texturing workflow - where did you set the seam (only one?).
Which command did you then use to automatically for proper projection?
Any steps between?

Hello, I have no idea how the tool works in C4D, but UV flatten (unwarp) function are more less the same in any software.

For this example I place the seam here, but you can maybe hidden in an other area.


Then I have 2 vertex selections, that force the flatten to straight the unwarp in U or V direction.

For U


For V


In Houdini it's called Axis-Aligned Vertex group, there must be something equivalent in C4D, as it's a common functionality to unwarp tubes and the like and force the uv island to be rectangular.
Maybe try to find something like "Straighten UV".

Thx for the impulse, PaQ!
Not yet sure which way to go...

Barry, thanks for the mini tutorial, which I can't quite follow though. The thing with the common point is not clear to me from the text. My English is poor.
But I also decided to learn texturing on this actually simple level first.
Even if I have not yet succeeded after so many attempts. I have always dodged it - it's time to face UVs.

Hi Lara,
this was the method I used on your model.
Cheers
Barry

Hi Barry, thanks a lot for your tricks ans solution! This is pretty cool. As mentioned before it is time for me to beat the UV challenge. So I did...
Best, Tom

Hello PaQ,
I did the UV texturing with RizomUV. We still had an old version here that I didn't know about.
There was a big fight because I didn't enable the "weld edges" option in the MOI FBX export settings and so all the individual parts were in Rizom. I was not able to merge them well. But once the penny dropped, and the weld option enabled in Moi it worked just like with the seams you showed.
I have since made the three versions I need - and they are perfect.
Thank you very much for the strong push into a topic, which I have always tried to avoid until now.
Best Mala

Glad to hear that, thanks for the follow-up !
