I am having trouble using the flow along surface command. I am trying to flow a textured surface along the doubly curved surface of what appears to be a vase. I understand that applying texture to a surface can also be achieved through displacement mapping but for the moment I just want to understand why the “flowalongsurface” command is not working for this particular situation as it seems everything is in order.
When I was looking through the Mcneel Forum I came across several flowalongsurface command failures having to do with the base surface being a trimmed surface. From what I understood a base surface cannot be a trimmed surface or else this command will not work correctly. I also seemed to understand that the base surface has to be created in a way which makes it similar structurally speaking to the target surface, for example if the target surface was made using the surfacefromcurvenetwork command then the base surface must be made like this as well. It seems that the key thing here is the target surface and the base surface need to be very similar in more than just the size of the outline. Have I understood this correctly?
This is why I created both the Target surface and the Base surface using the Surfacefromcurvenetwork command. I used the CreateUVcurve on the vase surface (target surface) to extract a base surface outline. I then drew a set of lines following this outline and used them to create a base surface using the surfacefromcurvenetwork command.
I have checked the directions of all three surfaces (Base surface, surface to flow, and target surface) and they all seem to be in agreement. I have also made sure that the base surface and target surface have the same UV point count (U: 50, V:50). However when I try to apply this command I end up with an oversized distorted version of what I need or the program freezing up and crashing. Could anyone help me identify the problem here?
I have attached below the rhino file if anyone finds it helpful.
Any and all help is very much appreciated!
