Hi friends!
I try to make a negative mold using BOOLEAN and when I make it, some complete edge loop disappears
Please, someone knows what happened and how fix it?
Thanks
HI @SURMULOT!
I’m having some trouble making out detail in some of the provided images. The polyframe is too dense. Please allow me to ask you a couple questions:
-
Are all meshes involved closed, watertight solids with a degree of thickness? Live Boolean will not work on 2d meshes or open volumes. I can’t tell for certain from your pictures whether the geometry is suitable for Live Boolean.
-
Check every subtool involved in the boolean operation with Geometry> Mesh Integrity> Check mesh. Do any subtotools report problems? This will need to be corrected before the Boolean operation if that is the case.
Thank you!
Hi Spyndel!
I’m used to doing these boolean operations and this is the first time it’s happened to me
I’ll show you with zoomed images
I have try CHECK MESH INTEGRITY and FIX but nothing happened…
Maybe you can test yourself dear Spyndel?

Hi @SURMULOT,
I’d be happy to have a look at your file, but you would need to contact support and provide the file for examination with your registered license. There are rules regarding file handling I’m afraid.
However, from looking at your pics I still have to guess at some sort of issue with the geometry in the pieces you are fusing. Live Boolean itself does not subtract geometry unless it has been overlapped by the new surface of the mesh. In that situation it will remove the redundant geometry. Any other time it only ever adds geometry as necessary where the meshes intersect in order to force quad and triangle polygons (ngons not possible).
I can see what is happening to your mesh, but not why. It may be the case that the geometry is not in a stable configuration for Live Boolean, and the edge loops in that area are collapsing as a result of the process. Please keep in mind that Live Boolean will alter the topology of the model where it fuses meshes together, and so it will destroy any textures based on UVs that were based on the previous topology of the model. UVs should be defined after a model’s topology is stable and not expected to change.
If you’ll forgive me for lingering on a point, please allow me to illustrate something I cannot determine from the available pics. Live Boolean requires closed, watertight solids with a degree of thickness for the best results. If your mesh is 2D or open any place, Live Boolean may fail to work as expected or attempt to close the hole, creating awkward geometry. While the pics of the interior of the head suggest an outer border that may have thickness, I can’t tell if the surface of the face is a 3D shell or not:

WOW! What a reply!!! Thanks! But at this moment, I’m busy on anything else, so leave this model. . . If you permit, I’ll be back on this post later when I have time to continue with it
Thank you again dear Syndel !!
