I have written my own graph generator based on the navmesh generator. This is to handle pre and post bake functionality on pretty complex maps.
It works great, but I cannot work out the save/load mechanism.
In an attempt to understand this, I have implemented the polar graph generator as outlined in your tutorials and get the same issue.
Tracing through the code it appears to generate and save the correct number of nodes, but on loading I get an error in the deserialisation.
Caught exception while deserializing data.
System.Exception: 22 nodes were serialized, but only data for 1 nodes was found. The data looks corrupt.
Thanks in advance
