I have a result file from the simulation of a floodwave. I would like to save / present the waterdepth over the time as a video and put an orthophoto behind the results.
As the wave moves through the area, there are a lot of dry nodes - varying with each saved timestep.
Is there a way in BK to hide those unused nodes, so that only the wave is showing, and not the whole computational mesh?
I tried starting with the legend at e.g. 0.25 m, but that is not hiding the unused mesh elements. In a GIS I would assign a transparent color to the lowest legend class, but that also does not seem to be possible in BK?
