I remember it being the standard method after Biohazard blob-shadow type. It looks like it's using a second, less-detailed, mesh for texture rendering but I'm not sure and it would be interesting to read further details on it. Oddly enough, you can see Clock Tower featured softer shadows with transparency while Tekken 3 didn't. Weird if you take in account the studios sizes and funds. EDIT: I hope someone tell me the name for this shadow projection technique before this site closes.
