Hi there!
I’m trying to close a small circular deficit in my mesh (across the blue lines), but whenever I run dynamesh, it is closing the entire hole (the green line).
I have tried various dynamesh settings. I have also tried using a torus to bridge the gap, merging it with the main subtool, and then dynameshing, but still it always closes the main hole (green line).
I notice a similar query here but was not answered: How do I close a curved hole?
Any help greatly appreciated.
Hello @arumiat ,
Dynamesh will attempt to close minor gaps in a single mesh, and remove any interior geometry that is overlapped. In this situation you don’t have a single mesh–you have two meshes that Dynamesh will read as open volumes. Since the interior mesh is located inside the other one, Dynamesh is probably attempting to close the gap on the exterior surface and sees the interior surface as geometry that should be removed.
Dynamesh needs closed 3d mesh solids with a degree of thickness to work. If you are attempting to fuse two meshes, they must be in this form and cleanly intersect. Dynamesh cannot be used to fuse open volumes or 2D mesh surfaces.
Following on from @Spyndel 's reply, if you have two open meshes that aren’t a closed volume then you can easily, and temporarily, make them closed solids with Dynamic Subdivision. Set smoothing to 0 if not required and add a tiny thickness. Apply the changes and now Dynamesh will work. If the gap is larger than the voxel size obtained from Dynamesh you can use your torus workflow to bridge the gap. Once Dynameshed all the interior polygons created by Dynamic Subdivision will be removed. Worked nicely on a simple test sphere with a crater that I just made. Good Luck. Cheers.
Appreciate the responses, thank you!
