When generating a navigation mesh using RecastGraph, I’ve encountered an issue where increasing the MaxStepHeight value causes significant discrepancies between the terrain and the navmesh in areas with pits or holes, resembling a deep-water lake. When using FollowerEntity as the agent, these agents tend to jitter up and down at locations with such discrepancies. Increasing the agent’s height can alleviate this issue to some extent, but if the drop-off is too large, it seems impractical to proportionally increase the agent’s height. Therefore, I am reporting this problem to inquire if there is a better solution. The root cause of this issue is the continuous up-and-down movement of the FollowerEntity, which was not immediately obvious due to the subtle elevation changes in the actual game map. To better demonstrate the issue, I have recorded a video where I set the MaxStepHeight to 1 to create more pronounced discrepancies.
