As model input data I select a raster stack with three bands. The first processing tool just needs specific bands of this stack which I like to select in the input dialog.
I create a 'Raster Layer' input that lets me select the layer. Then, I also create a 'Raster Band' input that has the 'Raster Layer' input as parent. In the GUI that is displayed as a drop-down menu and I can choose between the bands.
However, the model always takes the first band of the raster layer, no matter which band I select. The processes following the layer/band selection are connected to the selection of the layer, because there is no possibility of selecting the bands (see screenshot):
How can I make the processing tools to use a specific band of a layer?
