Thank you for your quick reply! This helped me very much.

Thanks for the update! I do understand where the problem is, but I still don’t have a solution for this. When projecting the vertices to the plane, th…

grov: I’d like to set an object’s transform to a matrix that is non-orthogonal, with say the z- still pointing up and the x and y axes pointing in s…

I think we are on the right way to solve our problem But I still have serious problems to imagine the process to flatten the surface. I created a pyr…

Seems that your method only recognizes the the alignment of the border edges. For example, if I modify your object by moving the border vertices, it c…

Yes, your right. This would only work on regular geometry… How does your script calculates the uv coordinates of the interior vertices? How does the t…

The routine would be pretty much the same as in this example: You start with 4 corner vertices which are connected through the border edges You …

The script has to recognize the 3d shape of the object in order to unwrap it in this way. To apply a U or V coordinate to a vertice, the script has to…

In my oppinion, there is no solution for this kind of geometry. I have no idea how to unwrap the object in your picture without distortions or without…

arketip: The automatic corners detection is really indispensable to make this kind of script pleasant to use. Yes, this is indeed very useful… I …

Your script looks really professional! But I don’t understand how you detect the corner vertices. My idea is to first let the user select the four co…

Hi Arketip, your script is GREAT!! I tried to map the model of the arc in my first posting and it worked. Then I tried to map the road on the terrain…

Thank you, arketip. I also thought about the problem with the already existing edges and vertices. I guess there has to be some kind of a tolerance va…
