I have a DEM layer with a no-data = -9999. When I load this in the QGIS 3D view it doesn’t seem to interpret the no data values, even though it’s set in the layer raster properties. See attached image for result.

Here’s the dataset I used in testing: https://www.dropbox.com/s/oobnqgbexf7n4ps/lds-wellington-lidar-1m-dem-2013-GTiff.zip?dl=1
