Using a shader on part of the screen libGDX
<p>I have used shaders to create simple black and white effects or blur effects across the entire screen. but is there a way to apply a shader to a portion of the screen. for example I would like to create an object in a game which is a piece of frosted glass that my character could walk behind. so I would Ideally create a shader to create a blur effect only on the area of the screen covered by the frosted glass. is this possible? or is there another approach more suitable?</p>

<p>thanks</p>
