Material transition across a single object
Is it possible to do a material transition in C4D over a single object, using something similar to effectors?
I need to be able to control the transition using a null or something similar.
My initial idea was to use black/white mograph colors on the alpha, and a plain effector going from white to black. But that only works per object, and not on a vertex/point basis, so I can’t make the material move across the object.
My other though is to use some kind of vertex painting, but I can’t figure out how I would link it to a null or do it based on the hierarchy somehow.My last resort would be to use a gradient and animate the coordinates or something like that, but I would have to do it manually, and my animation is pretty complex.
Any ideas? Hope it makes sense 🙂

You can create an Xpresso tag that accesses an Effector’s Strength at every point of an object and passes that into a Vertex Map.
Here’s a simple example.

I realized I should mention that in the example the top material’s alpha is transitioning on as the bottom is transitioning off. Technically that’s not necessary, only the top material needs to be affected, but I thought it might provide a little extra insight 🙂
