Obi Softbody's surface blueprint generation seems to do a good job on high-poly models with consistent vertex density, such as the example models of the dragon or the bunny. Unfortunately, it has big problems with any reasonably optimised models.
The main problem is that when generating a surface blueprint for a mesh, Obi is fundamentally limited to generating a maximum of one particle per mesh vertex. If the model has vertices that are not regularly spaced, then you run into problems when setting the Cluster Radius. The areas of the model with more densely packed vertices become overconnected for any given cluster radius value, and less dense areas become underconnected or even disconnected.
I wanted to see what can be done to combat this, so I just have a few questions if anyone knows:
1) Is it possible to generate intermediate particles on edges or faces rather than only on vertices?
2) Is there a better method for connecting particles than cluster radius?
3) Is it possible to limit the particles to the closest 3-4 connections to prevent over-connection?
