I have an object made up of cloned planes in z-space. I am using the formula effector to make each plane fade from pure black to pure white. The formula I have right now will fade the first plane from black to white and then the next plane will fade up and so on. I would like the planes to overlap so that the second plane starts to fade from black to white before the first plane is done. Here is the formula that I am currently using:

*clamp(0;1;(id<=t)*t-id)* Any help would be greatly appreciated. Thanks.
