The tools themselves are fairly simple but it is in their implementation that they find their power. This discussion section will serve better as a reference for someone who has already acquainted themselves with the general procedures of multires sculpting in the tutorial section. It would also be helpful to have worked through Chapter 4 if you don t already understand the basic concepts and terminology of mesh modeling. Multiresolution Meshes Sometimes after you ve seriously subdivided a mesh object to add fine details you wish that you could go back to the un-subdivided version to make large scale structural changes without disturbing the fine work you ve already done. Your best bet in that case is to start trying to push and pull the mesh with the Proportional Editing Tool and hope that things don t distort too badly. With multiresolution modeling though you can do exactly that. What begins as a simple mesh can be given increasing levels of detail yet each level of subdivision is maintained and adjusted as you work on the model and remains accessible. One could sculpt a head with incredibly fine details then later decide that the overall proportions of the face were off and fix them simply at a level of detail that could better accommodate such changes. A mesh is changed into a multiresolution mesh by clicking the Add Multires button on the Multires panel in the Edit buttons F9 . Once a mesh has been made multiresolution it cannot have geometry added to or subtracted from it in Edit mode. Existing geometry can still be transformed there however. Also at this point Shape Keys Chapter 8 and multiresolution are not compatible and Blender will prevent you from using them together should you try.
