Thank you Frank,
I’ve been tweeking since I’ve posted this question. And got quite a bit right. But at the same time quite a bit wrong.
The model looks pretty like the real one, but when I start moving some points around in the UV-edit. It bends the texture a lot. (Because the model isn’t 100% accurate)
I tried your way, and it looks prety good. But as long as I haven’t an accurate model it needs tweeking, tweeking and more tweeking. But there isn’t much budget and they want it to be perfect, so yeah…
Here you see how much I need to move the corners to align them with their template.
And if I try to realign the corners of the model, it doesn’t work anymore with the cloner tool.


Greets,
Matthias
