Increasing resolution of 3D image in QGIS GRASS NVIZ?

Question

I'm trying to display 3D data in NVIZ within QGIS, but the result appears very low resolution in comparison to the same data in ArcScene.

How do I improve the quality?

I've read the question on 'How to increase the resolution of 3D image in GRASS NVIZ' - but this is based on GRASS not in QGIS and the solution didn't appear to work for my data. Both raster and elevation model have been resampled to 0.5 m resolution.

How the data looks in ArcScene:

How the data looks in NVIZ:

I'm not sure about NVIZ. I would suggest, as an alternative, you look at another QGIS plugin called Qgis2threejs [https://plugins.qgis.org/plugins/Qgis2threejs/]. It can produce higher resolution 3D images than the examples loaded above.
