I’ve been reading but did not understand how to use or apply.
What I need is a wireframe plan where I can control the alpha.
I could not control this through other methods.
I found this method OutlinePass, but could not apply it.
Could someone please give an example?

Thank you!

you can use simple plan alpha and add some LineSegment

_line = new SegmentSet();
var lineSegment:LineSegment = new LineSegment(new Vector3D(), new Vector3D(), 0xFF0000, 0x330000, 1);
_line.addSegment(lineSegment);

Outline is a methode for cartoon style

private var _outlineMethod:OutlineMethod;
_outlineMethod = new OutlineMethod(0x000000, 0.5, true, false);

_myMaterial.addMethod(_outlineMethod);

Thanks loth!
I really did not know how to use the methods.
You can add more than one method in the same material?

Is there a way to control alpha using the linesegment?

yes you can use many method on same material

for alpha i think is 0xff000000 colors
first ff is alpha so 0x55ff0000 is red alpha transparent

Thanks again! I will try this!
