Zbrush | What if Mesh fusion doesn’t work

Then Zbrush will join the two surfaces automatically, and that’s how you activate Mesh fusion. Here are a few notes if Mesh fusion doesn’t work for you. Take note to Groupsloops high resolution surfaces before you run Mesh fusion and make sure that both surfaces must be under the same Subtool layer. Make sure Dynamesh is not activated and finally make sure that there are no Subdivisions. There is another common way this IMM Mesh fusion is used, which is for adding geometries onto your existing models.
