texturesample parameter2d with a custom node

I have followed…E4_With_VS2017

It works great, but I also require to modify the dynamic material with a custom node.
in other words I require to edit the default texture sampling to perform my own sampler, for instance perform a blur function
s.a :…tom/index.html

however I am not sure how to handle a texturesample parameter2d vs handling a texture object…
since the parameter already performs the sampling vs a texture object which can be sampled.


Spiral Blur material function has an example how to do that.
