Following two attractors
In this video I introduced a new controller in Para 3d V3.0 . Blend controller works just like blend map in 3ds MAX. you provide two different controllers (A and B) and s third controller which controls the blend amount. As blend amount increases from 0 to 1 the result of blend controllers moves from controller A to B.
For this video I have added an option to vector controller which can be used to normalizing vectors. you can download this controller from Here and please locate it under MAX FOLDER\Scripts\Startup\parametric array\controllers
