Hallo Jayme, thank you for getting in touch.
In order to produce a blur effect you need to implement your own technique, since there are several ways of achieving the effect. You may refer to our SimpleBlur sample, but you'd have to replace the Texture Sample node by a
Grab Screen Color node and set the shader's Blend Mode as Transparent.
I've also attached a small package with that exemplifies how you could possibly achieve an effect similar to Blur through our SimpleRefraction sample, with the aforementioned Grab Screen Color node being used.
You could also consider using our
Custom Expression node in case you want to apply any common technique through shader code ( blur example -

Hopefully this will help you decide on how you want to achieve the effect, please don't hesitate to get back in touch if you have any further questions or issues.
