Add additional details to low poly meshes by baking high poly meshes to existing normal maps.

Example workflow (Use Material Viewport Shading to see the maps without rendering):

• Model the low poly mesh and unwrap it. ]
• Press W -> Set Canvas, this will ask you to input texture dimensions. If you don’t need ID maps you can uncheck them and increase performance. You don’t need to do anything else, material is set up for you and maps will be saved automatically each time you save the file in a folder next to the file called “maps_filename”. To stop you from selecting the low poly object during baking selection will be locked for it.
• Position a high poly bolt on the surface of the low poly mesh and press E. This bakes it to the low poly. To speed up aligning objects to the surface: turn on snapping (Settings: Face, Center, Align Rotation)
• Bake more objects
• When your finished press W -> Release the Canvas
