Then you have a different crop matrix for each cascade…yes?
No, thats what the crop matrix does. It will make the scene bigger or smaller so that the bounding box always fits onto the shadow map.I’ve made no assumptions—I’ve never heard of using a crop matrix for cascaded shadows, and don’t understand the approach you are taking enough to make any assumptions.
as you both assumed that I was taking into account the scene geometry, which I am not.
What I described in my last post isn’t based on assumptions about what you are doing, it’s just the standard way it is done in the industry.
From the sounds of it, it is also more efficient and more straightforward than what you are doing, and will definitely eliminate the problem you have with zaggies, so if your current approach isn’t working I’d suggest just dropping it and starting over using the standard approach. If it has one advantage at all, it’s that by being the standard approach you can certainly find more information on/help with it.
I was under the impression that the way I've been doing it is the standard way. I've looked at 9-10 different references and none of them do it the way you just described. If you have a reference, I'll take a look at it.
