Milestone 3.3.12


  • Added disp_padding to set displacement bounds: The displacement bounds are now set with the disp_padding attribute of the polymesh node. Previously, this was set via the disp_height parameter, which was also used to set the amplitude of displacement, causing confusion and even rendering artifacts in some cases. (trac#2399).
  • Adaptive subdivision fixes: A bug has been fixed in the flatness-based adaptive subdivision code, and as a result the renderer now produces more stable tessellations in animation, and more accurately reaches the target subdiv_pixel_error set by the user. This has the apparent effect of reducing the number of polygons, because the old, buggy code was over-tessellating. (trac#2330)
