Load back into the game and fly the camera over to the planet you want to export. The notification on the screen will tell you which planet is currently being targeted (it will be whichever you are closest to). It will also tell you the name of the voxel you are directly above on the planet, which you can use to help set up the color/gloss/additive for voxels in your Config.

Use the "/ExportCM", "/ExportNG", and "/ExportADD" console commands to export the desired textures. They will appear as .tga files in the "C:\Users\18587\AppData\Roaming\SpaceEngineers\Storage" folder. The file names will have the format "PlanetProxy_<PlanetName>_cm.tga", "PlanetProxy_<PlanetName>_ng.tga", and "PlanetProxy_<PlanetName>_add.tga" respectively.

The first time you run one of these commands on a specific planet, the game will freeze for a while as the mod collects all of the voxel info for that planet. The higher you set the resolution, the longer it will freeze. Running the other exports on the same planet (or running the same export again after making changes to the Config and using "/ReloadConfig") will generally process much faster since the voxel info has already been collected. Running any export command on another planet will reset the voxel info.

NOTE: These files may appear to be mostly or completely transparent at a glance because the alpha channel is used for metalness (in the cm file) and gloss (in the ng file). This is normal and not an indication that something is wrong!

NOTE: The "ng" and "add" textures will export at half the resolution of the "cm" texture by default (less detail is usually needed for those). You can adjust this by changing the <ScaleReductionTexNG> and <ScaleReductionTexADD> values in the Config.

NOTE: The "add" texture is only used if there are voxels which have an ambient glow to them (i.e. lava or something similar). The texture will not export if there are no voxels detected with a <VoxelAdditive> value set.
