GetPointsAroundPoint issues

Hi, I just recently downloaded the demo version and so far I’m very impressed and love it. Right now I’m trying to generate points around a target location with GetPointsAroundPoint using a grid graph. Since I’m only using one graph the documentation says to use[0] as IRaycastableGraph, but when I try that it returns null and GetPointsAroundPoint throws its exception due to having a null IRaycastableGraph.

Any insight would be appreciated, thanks!


Linecasts for grid graphs are not available in the free version, so the grid graph does not implement IRaycastableGraph. That’s probably why it is failing.
