Custom parameter driven shaders

I wanted to understand if there is a way to include custom shaders in the application.
I am looking to build custom shaders which will be parameter-driven.

For eg: A chequered shader which renders 2 textures in a chess like format. In this shader I would want to give the functionality to change either of the two textures.

@PraffulSahu, unfortunately it’s not possible to include custom shaders in the viewer.
