I have a new shapefile layer in CRS 3857, in a project that has the same CRS. Under project properties, the measure tool is on ellipsoid WGS 84.
When i use the field calculator to create a new field for the layer and use the function "$area", the fields get filled with the correct values.
Now when i use the field calculator to add a virtual field with the function "$area", the values in the field represent the area value of the features calculated without ellipsoid (None/Planimetric).
Is there a way to make the virtual field function use the same Ellipsoid setting as the normal field calculator?
