I have a habit of solving my own problems moments after asking for help. 
What I had to do was make sure that the object that I am getting the texture from, has a “Material Instance Dynamic” variable (I called it “MatInst”)
I also needed to make sure there was a TextureSampleParameter2D node inside of the material, which I called “SurfaceTexture”.
Then when I clicked the object, inside of the ball object blueprint, I cast to the object in question (in this case, a “WoodenWall” object), I then got the “MatInst” variable, dragged off a “GetTextureParameterValue” node with the parameter name field set to “SurfaceTexture”.
Inside of the ball blueprint, is another dynamic material instance called “BallMat”, which I also have a TextureSampleParameter2D inside of called “BallTexture”.
I then get the texture out of the GetTextureParameterValue node and set the Texture Parameter for the BallMat to the SurfaceTexture we just exposed.
I am kind of a bit drunk, so this may not make too much sense. I hope it helps someone anyway
