I have a couple of raster layers in QGIS 3.28.2 Firenze. One layer is in Hillshade mode and the second one (on top ) is configured as Pseudocolor monoband and has mixing mode set as Multiply so the hillshade shows and the map gets the shadows that give a 3d look. Everything looks fine in the QGIS main screen and in the composer screen but when I export the composition to PDF or as a PNG image the hillshade mixing disapears and only the Pesudocolor is visible.

This is how it looks in the composer screen:

And this is what I get when exported:

Image exported

I tried to export asPNG and PDF, tried to lower the export resolution, invert the layers order, close and open QGIS and export again. It keeps exporting a flat image with no hillshade.

  • Afaik mixing is a poor choice for exporting maps. Some versions ago "mixed" layers even prevented map creation.

  • Oh! Do you know if there is any alternative method or workaround to apply a hillshade shading over a raster?

  • Have you tried export as displayed on the hillshade layer and then using that layer for map creation?

  • I just found there's an open issue in Github for this bug... "Layer blending mode reset on export for all file types #50526" github.com/qgis/QGIS/issues/50526

  • Until the bug is addressed can you get satisfactory results by making your pseudocolor partially transparent over the hillshade?
