Index SHP file export

In the most recent webinar working with NDVI indexing the shape file that was depicted on screen at 47` 50" in QGIS, the area colouring, is this done in Pix4d or in QGIS? All I seem to get is a shape file with areas of zero colour. I am running Postflight Terra 3D 3.4.37

You can do that in QGIS. You have to change the properties of the layer clicking with the right button of the mouse om the layer. And change the style of the layer.Choose Categorize.
