Hi,

I am looking to reproduce the glow effect from nvidia tutorial (cannot post the url here), if I understand well, we convert the first image to an "alpha texture" (black and white), and we blur this new texture.

How is it possible to create this alpha texture?

(Edit: the shader errors have been solved)

Thanks
