I have an effect that I'm trying to achieve and am only so far able to get partway there. I'm not sure if Max has the tools to do what I'm after, as I'm not particularly familiar with its physics or particle systems so I'm hoping that someone can advise me. This may well be a super obvious task that I'm butchering in my explanation so thanks in advance for your patience!
Image a static 3D array of particles, each set to a scale of 0, with an object moving through them all (E.g. a sphere). As this 'control' object passes over each particle, I'd like them to grow to a larger size, but not larger than the confines of the control object. Essentially, if we hid the control object, this would create the effect of the shape moving by 'creating' particles at its' leading edge and shrinking them behind them.
I can create an array of particles that fills an object, and then just move that whole group, but that's not quite what I'm after. I more want them to stay in place and grow/shrink in response to another object.
Here's a super basic handmade example of what I'm talking about. In this example the particles are cubes and the control object is a sphere:
And here's a super rough 2D version of the same principle which might be clearer?.
Hopefully I've explained this in such a way that it makes sense.
