OpenSubDiv Testing and Discussion Thread
Okay, I've been testing OpenSubDiv (OSD) edge creasing.
And I'm thrilled by it...
I have discovered one thing interesting. If you have your subdivision level set to 1 (4 quads per polygon), it appears that all edge creasing settings, 1-5, are identical. The top image below shows this. The subdivision is at level 1. The upper left vertex and the lower front edge are each creased, left to right, from 1-5. I see no difference in the resulting polygon position in any of those.
But with higher subdivision levels you will see differences, such as what show in the lower image in which the cubes are Subdivided to level 5 (4 to the power of 5 quads per polygon) with edge creasing, left to right, to levels 1,2,3,4,5 on the bottom edge and the upper left corner.
The tools for edge creasing are in the Tools Tab with Polygon Group Editor selected.
