[Plugin] trying to render an input texture onto a renderTarget

Eventually my goal is to do wave interaction plugin but in my second step in this process I want to take an input texture and pass it onto the pixel shader to be blended with a color.

Issue I am here is my blending is working but I am not able to get the texture to show up. I have my process and problem documented here.

If anyone can help me figure the problem out then it would be awesome.
My github of the code project is here.



Resolved in the second post. It was the issue with the sequence of variables called in the Pixel Shader. Check out the solution here.
