Hello

I work many times with QGIS and CIVIL3D, and when I create a surface from Civil 3D and export it as a TIF file in order to open it in QGIS 3.4, the elevation data from this tif file appears "flat" (i.e. the same elevation throughout the area). However, strangely enough, when I extract contours, these are correct. I do not know how to fix this problem. I attached a snapshot.

Thanks everyone :)
