I wonder how the effect as shown in the picture was made?
I mean that blurry shadow. This shadow appears on every block layer, which means that it is not a shadow generated by shadow mapping.
I would like to have a similar effect. I had the idea to modify the entire model before displaying it and it is feasible for me, but I would like to get the same effect with a vertex shader.
Unfortunately, as far as I know, apart from shadow mapping, it is impossible to influence the surrounding vertices, or at least I don’t know how to do it.
Anyone advise something?
