    Hi Nice Unity People,
    I tried to do a billboard particles system using sprite particles.
    i need the alpha around the particles to make it nice and smooth.
    but the alpha turn in black as you can see on the screenshot >>
    i use a psd files with alpha channel,
    the frangement shader look as that >>
    float4 FS_Main(FS_INPUT input) : COLOR
    {
    return _SpriteTex.Sample(sampler_SpriteTex, input.tex0) * input.color;
    }
    Any Idea ?
