Hi,  
Hoping someone can help me as I am fairly new to Paraview. I am trying to insert a Digital Surface Model with a jpeg overlay. I initially tried to convert the dem to a netcdf via ArcGIS Pro, however, Paraview kept crashing with that file.  
So I ended up creating a .obj file via QGIS and that seemed to work, however, I am still having a few small issues.

1. My overlay jpeg doesn’t line up exactly with the obj file, also seems a bit exaggerated.
2. is there any way to get the bounds into meters?
3. I can’t seem to get Z (elevation) correctly on the axis.

I have attached pictures, hoping my questions make sense.
