I guess the title is the best way I can define the question. I'm trying to embed the cup into the body of the dog.

enter image description here

The cup has more vertices than the body, so since I'm pretty new, I can only think of two ways to do it. The first is to shrink-wrapped it around the body then used boolean union. But in order to see it I have to either add a thickness modifier or extrude it, both of which make it look like a patch instead a part of him. Now I'm trying to subdivide edges to create enough vertices to merge together, but in render mode it shows black between the two meshes.If I make faces after subdividing edges, it becomes distorted. So I'm not sure what to do now. Any help would be appreciated. I know you might be thinking, "dude, just make up a texture with gimp/inkscape with that shape and UV wrap it."

Yes, that would work, but I wanna be able to create a vertex group with it and change it with a drop of a hat, then quickly render again. So I would really like to embed the cup if I could. The blend file is located at http://www.pasteall.org/blend/39692

  • $\begingroup$ the black faces are just flipped faces " recalculate the normals to resolve this" the second seems to be the best method just use the snap option to snap the dog verts on the cup shape ( like retopology workflow ) $\endgroup$

  • $\begingroup$ Thanks for the replies. I looked into retopology by watching some tutorials. I don't think that's what I want to do. Or at least I don't think so. The tutorials always said HOW to do it by not WHY. What is it used for? So I'm going to assume it really can't be done. I've posted it on another forum and didn't get a response. So I guess I'll have to do it the hard way. :( $\endgroup$

  • $\begingroup$ Mattgolfs, is the body of the dog supposed to appear solid, or hollow? $\endgroup$

I maybe should ask for more information on this before I attempt the answer, but I'll take a stab at it anyway. I'm disinclined to agree with Mr Zak's recommendation to use the Boolean modifier, because I find in too many cases, it gives ugly geometry and thus, inferior results. But here's what I'd do.

Assuming the dog and the cup are separate meshes, I'd make a duplicate of each. Starting with the duplicate of the dog, I'd keep the part of the torso boxed in green,

[enter image description here]

and hide or discard the remainder. If the geometry in the remaining part of the torso is insufficient for modeling the finished result, I'd add loop cuts and edge rings as needed to make for convenient modeling.

Next, I'd scale the cup so that it is the size I want, and position it within the torso at the desired place. Switching to wireframe view, I'd hide all but one flank of the dog torso, and if the flank intersects with the cup object, I'd switch to edit the cup, and move the sides that penetrate the flank so they are co-incident with it, adding or removing geometry as necessary. Repeat the process on the other side, and the sides of the cup now conform to the geometry of the Dog's torso. Discard the copy of the dog's torso, as it has largely served its purpose.

Select the original dog, and place the cup along side of it in the desired position and orientation. Add the geometry necessary to be able to demarcate the red lined area in the above image on the side of the dog. Remove the parts of the dog within the red lined area on each side, and if the dog is to be solid, bridge from one flank to the other. Make the cup visible, within this area, and if desired, combine it with the model of the dog using CTRL - J to make a single object.

In my opinion, the fact that the cup has more vertices than the dog is not a major issue, in most cases.
