Ok cool thx a ton for the help. I even got a reply from the OG AI programmers offering theyre help, but they said its been so long since they worked on it they will have to get back to me on it. So, ya I'll try the agression thing you mention, setting it to 1.7 I also wanted to increase the hunting/smell/visual range so the TRex will actually persue prey when its in visual range (nothing more frustrating then when he's clearly in visual range, but can't 'see' it yet.)
Well thx again!
