WTF, you are damn expertthree-point system is for softer shadows, that's pretty much same as unreal
But, the lighting settings you do with the three point system would mean jack if you don't double the rendering pixels for higher resolution as the shadows will be sharper and lighting would be bright, so if you have your pixels set at 1.0, with the lighting you use, change it to 2.0 or 3.0 for more sharper lighting, if you keep it at 1.0 then, your lighting you use for editing will look bland when rendering
Okay, I don't think I'll reveal any more tricks, you will have to pay for it
