i have a plane which i am rendering onto.
but i want to split the image onto 2 planes each with half of it on , so i have a left and right
now i tryed in the pixel shader
if ( uv.x > 0.5) alpha = 0; // for the left side
if ( uv.x < 0.5) alpha = 0; // for the right side
but there has to be a better way to do it
