To illustrate what i mean, i made a little gif:
I need the Sphere, or any other object for that matter, create a falloff kind of mask on proximity to other objects, this has to be dynamic, the white circle has to follow the sphere, as in the ground plane there in the gif, and disappear at distance.
And since i want to do this with other shapes of objects, it doesn’t have to be always a circle, it has to have the shape of the object.
The way i thought of this, is to gather the distance from the moving object to the wall or floor, and paint the wall or floor based on that distance.
Now, is something like that even possible in UDK?
