I can get all the required data from my mesh rep but it seems OSD expects edges to be ordered in some way. After I set validateFullTopology to true I get a message saying: \"_FAILED_ORIENTATION_INCIDENT_EDGE - vertex 0 orientation failure at incident edge 0_\". \r\nIs there a specific edge ordering I have to follow when transferring edge indices?

For a mesh with one million faces the **TopologyRefinerFactory<TopologyDescriptor>::Create** function takes about **1.4** ~ **1.6** seconds. I believe I’m building the library in release mode so I just want to make sure this is a normal timing since I don’t have anything to compare it at the moment. \r\nThis is used in a modeling application where topology is changed often. Unless my timings are off, I think I have to go with a custom descriptor. I had to make some modifications in my mesh rep so I’m going to give it another try today. Up to now with a custom descriptor I manage to lower the creation time to **200ms** but I think I was passing some relation wrong because after topology changed I was getting a few console messages from OSD about face correlation etc. "}}
