Do you think of these lines?
/* this shadow needs a directional light */
FilterPostProcessor fpp = new FilterPostProcessor(assetManager);
DirectionalLightShadowFilter dlsf = new DirectionalLightShadowFilter(assetManager, 1024, 2);
dlsf.setLight(sun);
fpp.addFilter(dlsf);
viewPort.addProcessor(fpp);
It doesn’t work in my case. Even if I set rootNode or each node to shadow mode cast and receive.
It worked year and something before, but it was bugging: Rendering shadows on the edges
I’m open to lesson about shadows, but no tutorial or whatever is wrote here didn’t work for me.
