Gradual transparency of elements into the backgroud - dx11

vvvv beta question
2

hey u need to enable blend first, add blend render state set to blend, then, if u don’t have alpha on gradient u need to do something like
if (col.r<0.001) {col.a = 0;} in ur shader

or just col.a = col.r, if u need softgradient
or u can try to use set alpha on ur gradient color…

the problem also u have black border where u have white border that makes it not obvious what cha wanna do.
