@Ch40zzC0d3r, thanks! Here it is a combination of stencil shadows (which are somewhat slow but its not extremely bad cause most models are not that high poly) and those shadows for (WED) blocks for rocks/structures/vegatation. I personally don't find stencil shadows buggy by the way, maybe I am just lucky . In the video I am playing the game on a medicore laptop, so I am quite happy with the performance.

I actually wanted to use the custom/shader shadowmapping but I can only get it working with new projects, not with this one. Those are faster with still ok quality but the basic one that comes with the gs3d install only works with outdoor scenes iirc.

Than there is decal shadows which you can try for e.g. top-down games, but I am personally not really a fan of those.
