Help Mapping texture

Hello
I need help mapping a texture,
is it possible from a material with straight lines to make it radiate from one point.
like that

Also the help window when I type texture command is not really readable in french it doesn’t show the accent and the pictures

Not sure whether you are looking for the pinching look like you sketched on the left side or if the texture would needd to be just oriented along an axis…

PS: Rhino 8 WIP has procedural wood textures…

Hello Thank you for your reply,

Yes it has to be pinched like you did on the left branch.
Can you explain how you’ve achieve it ?

The material I use is a metal with straight stripes engrave on it

Look at the file. I’ve used custom object object mapping with a separate surface.

Yes I saw it but I don’t understand how you did it !
I try different functionality but it is always hazardous.
So you create a surface with the same shape then custom mapped your original surface by selecting the new surface.
It gave me this really difficult shape to mapp
I try to change the degree but give me only bad result

I think i got all wrong and i find it difficult to have more info about this feature
