Hi ! (First post, yeah !)

I’m trying to exclude from navmesh instanced foliage’s top.

Here is foliage placed and you can see there is NavMesh generation on top. (Foliage used here is a placeholder, for reproduction purpose, of course)

I found potential answers :

  • Increase “Min Region Area” of the NavMesh => it remove 70% of foliage’s top, but even with a large value, some foliage’s top remain
  • Use “Dynamic Obstacle” on foliage’s mesh => It remove all foliage’s top, increase performance, BUT with HISMC, the navigation datas don’t take into account rotation of foliage instances.

So this is my bug report : I think “Dynamic Obstacle”, when used in HISMC take into account rotation of the global component instead of instances.

Thank you in advance for your answers.
