Start_navmesh_baking problem

Omniverse Isaac Sim
1

I installed the new version of isaacsim, the 4.5.
Trying to use replicator and launching the sdg_scheduler.py script located in \isaacsim\tools\agent_sdg, It keeps giving me the error “NavMesh building failed. Please check whether the stage has a valid NavmeshVolume. Will not load assets to scene.” although the environment I load contains the NavMeshVolume. I also did some tests and this error does not appear if I simulate the same process from the editor provided in the interface.

Do you still have this problem? If yes, could you provide the command and its complete log?

I solved the problem. It was just a matter of the parameters used for the navmesh backing, probably in version 4.2 they were set by default to values ​​that worked while in version 4.5 they have default values ​​that are not good.

Could you share the command you used when encountering this problem, along with the solution you found? Sharing this information might help other developers facing similar issues.

I simply set the navmesh parameters related to the agents:

import carb
from omni.anim.navigation.core import NavMeshSettings
settings = carb.settings.get_settings()
settings.set(NavMeshSettings.AGENT_HEIGHT_SETTING_PATH,180)
settings.set(NavMeshSettings.AGENT_RADIUS_SETTING_PATH,50)
settings.set(NavMeshSettings.AGENT_MAX_STEP_HEIGHT_SETTING_PATH,0)
settings.set(NavMeshSettings.AGENT_MAX_FLOOR_SLOPE_SETTING_PATH,45)

I’m sure this solution was already reported in another discussion but I don’t remember which one.
