I am implementing a requirement where a point cloud must appear as a circle instead of a square.
- I created a custom mesh and applied a shader material with
- I implement a simple circle fragment shader where the inner color is Opaque(Aplha = 1.0), and the outer color is transparent (Aplha = 0.0).
For some reason, the mixing of two colors in not result in a proper alpha blending or transparency. Here is a playground sample.
Expected result:- The fragment outside the circumference area must be transparent and blend with anything in the background.
Any help to make the transparency work is highly appreciated.
