-max 13
-nv 0

An unexpected error occurred.

Hello, @dienDan10

I recently discovered a similar OOM issue while processing high-resolution DEMs.
I’ve applied a temporary fix and uploaded it as a Docker image for version 1.13.2-release only. an official release is scheduled for the near future.

If possible, please try running this version.

docker image pull gaia3d/mago-3d-terrainer:latest 

or

docker image pull gaia3d/mago-3d-terrainer:1.13.2-release

Thanks you for the quick update, @znkim
About the fix, can you tell me more about it. Should i be concern about anything that might affect the output data?
