Need some help with texture map and displacement map

Hi all!

Hope everyone had a nice Thanksgiving! I’ve been struggling to properly texture map this cloth I modeled and I was wondering if anyone could lend a hand. Currently the best I can do is using the UVEditor to custom map it, but the mapping is following the control points of the object and distorting the map in certain areas. Is there a better way to approach mapping this? Here are some images for reference. I can also upload my rhino file but it says its too big to transfer via this post.

Rendered:

Shaded:


(You can see how the isocurves are making the map stretch in certain areas when applied.)

I’m also hoping to use a displacement map to add some more realism to the fabric texture. I’ve never used the displacement feature before so I was having some trouble getting it to properly work. If anyone can point me in the right direction that would be great. It problem could also be with the actual image. I’ll attach all those as well.

Thanks for the help,

Addison

Hello
For the texture there are surely 2 solutions
Remesh the surface with quad remesher in Rhino 7. It will certainly suppress some of the distortions.
The second method is to drape with a physic engine like Kangaroo or Flexhopper. You 'll get a correct looking. There are lots of examples.

Thanks for the reply Laurent! I’m not that advanced with plugins yet, so I haven’t used GS or Kangaroo before, but I’ll certainly look into quad remeshing. On the other note, I am looking to learn GS and other engines like Kangaroo and Flexhopper. What did you use to get started? I’m not sure how many resources and tutorials there are out there.

Is it a single surface and your problem is the changing density of the isocurves? You could try to rebuild the surface with a high density. I hope you get nearly the same shape, but with homogeneous isocurves. (Keep the original, maybe you need it later.)

Hi Micha. It is a closed solid polysurface that has been “flowalongsrf” to achieve the form I was looking for. I tried rebuilding the original surface and changing the density, but sadly the texture mapping still was stretched in certain areas :frowning: I’m not sure how custom mapping works in rhino and if there is a way to override how rhino uses the isocurve/control points to create a map, but that would be useful.
