is there a way to increase the precision in the rendering of shadows? I have set a high epsilon to make shadows very near to planes, because I have to handle planes for a card game, and I have to put multiple planes one on top of the other, keeping the shadow between the planes to define the borders. Currently, as soon as a card goes a bit far from the camera the shadow jumps upon the card. I have decreased the camera “far” parameter as much as possible to keep everything inside the camera range (thus increasing the accuracy, I suppose), but it is not sufficient yet.
Do I have to manipulate frustum or something like that?
I am using a DirectionalLight + StaticLightPicker + TripleFilteredShadowMapMethod, but if you have a different combo to suggest I can change them, I just need to lighten a table from top, a very simple scene.
