I've been experimenting with few things and was thinking of adopting two new visual additions: distorted shadowmaps & Shade-C HDR. Here is an example of shadowmap with & without new effect:
Without..
With..
Unfortunately there are some inconsistencies in almost 50% of the cases because of the shadow UV mapping..
I can (probably) solve this in future levels but even in this percentage they seem to be effective & give the surroundings a nice additional quality (I think?). They will be present in following level reworks so that we can all see if this is something that should be implemented or not.
