There seriously is a lack of cameras in the game. I tried to make it as "dynamic" and as action-filled as possible only by using the cameras. To be honest I think it worked, it's all very fast-paced even though there's not much action actually going on.
The film director on Mac is a real pain because you can not save anything. It's so buggy, it's really annoying You can't upload anything either actually but I don't care about that.
So I always have to do it in one go, and then record the whole thing with screen capture.
I'll be doing more soon, and I have an interesting one waiting to be uploaded also. It's very short but it's a classic for any fan of the first game in the series
