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 !
