Painting effect
-
Hello,
I need to create a model that consists in a small part of a city like this:
I already have the buildings but I need a ruby function to paint the floor with the same effect of the picture. I am doing a plugin of wireless coverage so the red zone means good reception power and the green zone means low reception power.
Is there any way to achieve the same color effect to paint the models floor?

The only thing I could find even close to this was Chris Fullmer's "Color by Z". However, this assigns a color gradient according to the z value of a face, that is, how high above a datum plane. Unless I missed some recent development, I do not recall any color gradient tool that works radially on the ground plane from any specific center point. The answers I got suggested that you would apply a texture with a color gradient to the surface. There may be somewhere out in the wild, something like this.

You can use the ruby Gradientator. You need the surface to be divided into many square faces Place the model focal point at the origin and run Gradientator on that surface. You might want to make a radial pattern of edges.

And now, I recall having looked at this thread. Sorry for any misinformation, and thanks to pbacot
