i have NVIDIA TNT 2 32mb
i didn´t know that i can look better the shadow... explain me more, or tell me if that video card it´s old
I already thought so... WME falls back to that simple shadow (which means, it uses just a simple PNG file, in the 3d demo it is "shadown.png" in the actor's directory) on older graphic cards and if I remember right, the TNT2 belongs to them. But you can also activate the "simple shadow" always, so please check your actor definition file (e.g. "actors/trinity/trinity.act3d") for the option "SIMPLE_SHADOW = TRUE" (or FALSE).
I could try to explain a lot, but it's easier for you to check the docs at "Inside a game -> 3D characters support -> Actor definition file". The supported real-time shadows use an additional light above the actor's head. If your "SIMPLE_SHADOW" option is set to FALSE and you still see this "black blob" instead of a real shadow, your graphic card unfortunately doesn't support them.
