How can I transfer normal map from different subtools to one subtool(lowpoly consist of one tool and high poly from different tools)
I don’t fully understand the question, but you can combine multiple subtools using the free subtool master plugin on Pixologic’s website.
As before, please include your version number that you’re inquiring about.
With the PC version you can use ZMapper to create a projected map. The instructions for that are in the online documentation, found in my signature.
With the Mac version, you can use the Tool>SubTool>Project all feature to copy details from one mesh to the other. You can then edit the mesh to fix any problem areas before you create a normal map using the Tool>Normal Map menu.
For example I have a high poly(human+clothes=2 meshes) and I should make a lowpoly with normal map(a human and aclothes is 1 mesh)
