not easy to begin … first it could be good you internalize the curve you use.
Right click on curve component.
As I said size matters, if you don’t see the protusion it is because your protusion is surely too low
N is the normal and if it is a good normal its vector length is one. So you protrude to 3 units and a wall height of 3600. Just change the slider range.
Third it is better not to show you have a cracked version of Rhino. Many began like that but that’s not a reason.
I don’t understand.
Ist it that ?
you have put X domain and Y domain pixel domain, but you input UV data that have 0 to 1 domain
=> change that
And if you want to change the orientation without changing the image
