Is it possible to merge two sculpted meshes? If you want to make a 3d printable mesh, you want to make it hollow... so you copy the mesh and scale it down, inwards. Then you make faces between those two meshes... Is this realistic to make with an complex sculpted mesh, or should this be done, before you make the complex sculpting? Or should I retopology? Also I sculpted the face/head and the hair in two seperate meshes, also the eyes are seperate... how do I efficient merging all those meshes into one? Many thanks and happy modeling :)
You may use a Direct Union option of a BoolTool add on.
You can join multiple objects with Ctrl+J.
Well just for the 'merging two meshes'. The best way I found is:
- Ctrl + J (join meshes)
- on Sculpt Mode with F Snake Hook Brush, mix the extremes of the two meshes until you make a kind a "soup" with it
- smooth it out with the F Smooth Brush.
When 3D printing a closed "water tight" object, don't worry about making it "hollow" Just take your single, sculpted mesh, and export it as a stl. The slicer program will fill this with a grid to support (this is what the infill % setting does).
If you really are keen making something "hollow", just copy paste, scale down a bit, and then boolean subtract.
If you are having with the boolean operation, I suggest you use the Remesh modifier first.
It is definitely possible! I had the same question.
To do so, you can use a boolean modifier to create a Union between the two meshes. The two meshes will join beautifully with no internal faces and you can smooth out the seams (may need to re-enable dynotopo) to create a single mesh. I got this information from the following youtube video:
Tested it in Blender 2.78 without issue. Make sure to move/delete the original piece you merged after applying the modifier.
