Second one looks awesome, I’ll try it.
BlenderGIS uses Google and MapBox info so, it is not useful for me right now, but thanks! (is not open data)
First option cannot be useful because I’m using UE5.
I’m using terraform to import the DEM with coordinates and the thing is that I need to import the TIFF image file and texture the lanscape mesh with it and it must be automatically alligned ( I thought the Georeference plugin should help me with this but there is not much info about it)
