I am trying to use generateVisualContent delegate to create a procedural line mesh, and I am having some issues. So imagine a vertical line segment from A (bottom) to B(top). I want to draw a line from start to end with a width value. So say w = 5 * Vector2.right. So my vertices for a given segment should be: 0: A.position + w 1: A.position - w 2: B.position - w 3: B.position - w 4: B.position + w 5. A.position + w Right? I set these vertices with the SetAllVertices method, followed by a series of SetNextIndex calls from 0 to 5. Then nothing appears on screen. Interestingly when I set the indices in reverse order, from 5 to 0, I get something. Half my mesh is now visible, but I can't figure out why the other half (the second triangle) is not appearing at all. I tried changing the order of the vertices and I think I tried pretty much every combination, but still no luck. I feel like I'm doing some dumb mistake and it's driving me crazy. HALP!
