      I have a component that has a color associated with it. when I have it selected and open "Entity Info" on it then click on the color, a "Choose Paint" panel opens and I can edit the Opacity (set it between 0 and 100). I want to access this value in ruby. I can get the colors for example: "ent.material.color.red". But "ent.material.color.alpha" always returns 1 and not the color of the opacity. Clearly it is stored somewhere but I do I get this opacity value?

      Thanks in advance,
      Dave

        Use
        entity.material.alpha
        to get it, and e.g.
        entity.material.alpha=0.5
        to set it [it's from 0.0 to 1.0 - transparent to opaque]
        A color also has two equivalent alpha methods [a color has [R,G,B,A]] BUT it doesn't change what is displayed for a material, no matter what the color's alpha is set to be. The color.alpha is 0 to 255 NOT 0.0 to 1.0
        From v8+ a color's alpha does affect it's transparency when it's used to color a face made in a method like ' view.draw(GL_POLYGON, coplanar_points_array)', where you have previously made a suitable color object [with alpha for transparency if desired] and then set it using view.drawing_color=color [in previous SUp versions such faces always came out as black' whatever color had been assigned - now it's fixed]...
