Point color transparency

Is there a way to set the color transparency of different points in a point cloud?
This is what I thought would work but did it not have any effect on the transparency:

cloud.Add(pt, Color.FromArgb(a, r, g, b));

a = (0.0,1.0) and r,g,b = (0,255)

Hey @sothorsteins,

The alpha component has valid values of 0 through 255.

Hey @dale
I have also tried values between 0-255 but it has no effect on the transparency. Here are some of my points that are supposed to have different transparency values.

Perhaps Rhino doesn’t support transparency on Point3d objects?

Hey @sothorsteins,

Can you provide a 3dm file that isn’t drawing correctly? Also, what version of Rhino are you using? Can you run the SystemInfo command and post the results here too?
