about lights 3dgs only supports stencil shadows z-buffered volumetric shadows are based on distance between light source and objects these kind of shadows produces that the shadows looks bigger when the object is near to the light source or smaller when the object is far to the light source
z-buffered shadows only produces far shadows or near shadows but the scale is the same.
the ones in A6/A7 are still volumetric shadows. a more common term for volumetric shadows is stencil shadows. that's exactly what you see in A6/A7. you should be requesting that stencil shadows have perspective -- vertex-based projection instead of object based.
for your problem, you should ask in the level editing forum. it could be a problem with your build settings. or stencil shadow settings in your code. in fact at the moment it's not a good idea to apply shaders to level geometry (if that's what you're doing) for speed reasons.
sorry i can't be more helpful.

Volumetric Shadows (PRV) already exist in 3dgs as you can see when you add a light in wed, but this lights can't be moved in real time, the lights emitted by entities are different because only can produce stencil shadows.

stencil shadows are the most common implementation of shadow volumes, or volumetric shadows, or whatever you want to call it.
stencil shadows ARE volumetric shadows.

I support OrangeBrats request for an accurate perspective based real-time shadow (stencil or shader, I did see both so far). Here is a short explanation what Brat and me try to tell. I painted a little pic in Gimp very fast to illustrate that (sorry for the typo):

Maybe you were confusing perspective with depth?
but we would like stencil shadows to have perspective.
