For a project I have modelled the upper and lower boundaries of geologic layers in the subsurface. The resulting rasters are stored as ASCII files with a NODATA_VALUE of -999. However, when I visualize the ASCII file, using the qgis2threejs plugin, the pixels or cells that have nodata are shown as 0 (see images below).

Is it possible for the qgis2threejs plugin to recognize cells with a nodata value and visualize only the part of the raster with valid values?

Create a polygon layer that represents the area that data exist and use it for the "Clip DEM with polygon layer" option.
