Nvblox mapping issue

while mapping we are facing an issue, such that the 3D reconstructing map disappears (t-1) as we move the robot further (t). It would be helpful if you could help us troubleshoot and solve the issue to fast track the progress.I have attached a video of the issue we are facing right now.

Best,

I have the same issue here. Even if I set the map_clearing_radius_m parameter to -1.0 (less than 0.0). It clears the mesh and costmap.

Hi @muthukumar1

The map is set to decay at a certain rate by default (to avoid corruption due to pose drift)
You could turn off decay by setting decay_tsdf_rate_hz to 0.0 here.

Let me know if fix your issue.
