When using Shrink Wrap, the surface of the object is very smooth before using the tool. However, if you transform the Shrink Wrap input value very evenly, the surface shows boundaries that should not be visible, such as the Rendered View on the left side of the image. If you look at the wireframe, the individual meshes are very detailed, but the overall surface of the object is not smooth, so when you try to render it using a program such as keyshot, these boundaries are visible and cannot be used. However, if you change the target edge length and offset values, the shape will change, the small expression part of the object will be damaged, and small gaps will stick together, so it cannot be used.
Additionally, the smaller the Target edge length value, the more prominent the problematic boundary becomes.
I suspect that the result is like this because the surface of the object to be converted has already been damaged, no matter how detailed the length value is because it is first converted into an uneven mesh in the virtual world and then shrink wrapped.
I have the same problem on both systems - mac m4pro and windows desktop ryzen9700x + 4070super.
Sometimes it helps to mesh surfaces / extrusions / polysurfaces before running shrinkwrap
First of all, thank you very much for your opinion.
In response to your feedback, we very gently converted the mesh and then shrink wrap it, so the result is better than before, but boundaries are still visible.
What do you mean with boundaries? The mesh edges?
I’m sorry. As I am Korean, I have many problems communicating because I use a translator. This refers to the same part as the red line in the image below.
I think they mean the sort of Moire pattern within the mesh… Well, it’s where the grid isn’t curving basically I think.
Have you tried TriangulateMesh
then Smooth
? This may get rid of the repeating pattern where the quad meshes are not capturing the curvature of your toriods.
All good, that is the render mesh. You can change the settings here:
In Keyshot for example you can also render nurbs. Have you tried that?
This is an option to choose whether NURBS objects will appear smooth when viewed. What I am saying is that when ShrinkWrap is done with a fine mesh, the smooth curved surface becomes angled in stages, unlike when it is NURBS…
I wanted to use shrink wrap immediately to even it out, but the method I taught at the time increased the work steps, but the final result was produced with the desired quality.
When rendering with KeyShot, if the objects are grouped, it is not possible to express the welded parts like in real life, so the purpose was to shrink wrap them and then touch them gently in Zbrush. It was a great help. Thank you.
Yes, after all the result of shrinkwrapping is a mesh so faces are always planar…
