Added a new api function to stich multires grids on specific faces in a mesh, subdiv_ccg_average_faces_boundaries_and_corners, and changed multires normal calc to use it. VTune profiling showed that this was a major performance hit once you get above 10,000 or so base mesh faces and/or have a high number of subdivision levels. Here's a video comparing the difference. Note the bpy.app_debug switch is not in the final commit. {F10145323} And the .blend file: {F10145346} Reviewed By: Sergey Sharybin (sergey) Differential Revision: https://developer.blender.org/D11334 |
