Texture along the shape of the mesh I have been looking for a solution to this problem for a long time, and getting to this was my last alternative. I intend to correctly texture my mesh as the image below:



As you can see, it is an every day situation but I would like to know how to solve it in the best possible way without making an extensive mapping of the figure that forces me to make a larger UV texture image in every sense.

I tried many ways, but I did not get the desired effect. I think that my biggest problem in this situation is that English is not my native language, and therefore, I have difficulties to find the exact search title of my problem. (please consider this before mark my question as possible duplicate)

Thank you very much for your help.
You should use Follow Active Quads.  The problem you're seeing is because the geometry doesn't have a lot of detail so it's not giving you nice curves.  Add a Subdivision Surface modifier and you'll get better results:



You may need to tweak the UVs a bit still in a couple of spots but I think you'll get really close with this.
