Merging tools isn’t enough for my work, I need to be able to export tools as single, non-intersecting meshes, so I need to be able to get rid of the intersecting parts and weld the tool together to create a single, solid tool.
Thank you kindly.
ZBrush 3.2 has a welding feature, which 3.5 will get as well when it’s released later this month.
In 3.1 you would have to merge the tools and then use retopology to create a new mesh with details projected from the merged one.
