how surface paint on column only one side?

[Anonymous]

Hi
I have some column. In the column I want to use four different surface paint for four sides.
When I use surface paint, it automatically painted to all four surface. Why?
But in beam, surface paint is working one side, but in column not one side why?

That's just a custom name. You can use whatever you want as name.
The list shows any modifier names used in other profiles.

Another approach would be a custom Surface that colours based on direction - maybe using an adaptation of something like the Lumas or Falloff shader to take world space direction into account.
