A quick benchmark on my system (i7 4790, files stored on a samsung 840 evo SSD):Ģ0.7 million triangle mesh, object space normals baked at 2k res with no SS Handplane is a lot faster than xnormal- The bigger the mesh, the greater the difference in speed. There shouldn't be a limit to maximum mesh size except for situations where you run out of system memory. I haven't ever tried to bake 700 million triangles but I regularly bake 10-50 million triangle meshes and they are quick. Sending that much data to the GPU is slow and you are forced to do the slow step first which drags down iteration time. The GPU bakers like knald have the fastest AO calculation which is a big advantage over CPU based bakers (handplane and xnormal) but handling really big meshes is where they struggle. If your biggest concern is handling very large meshes you should give handplane baker a try. No other one I tried can load 700 mil polygons and bake mega 16384 textures.
