The only thing which can be put into the Tex slot in the Texture 2d node is a Texture Asset node. What I want to do is place other data into that slot aside from a texture asset node. In other words: I want to take the RGB data that was changed through other nodes (multiply and such) and plug that back into a texture2d node so I can change the uv coordinates AFTER it was already changed. So yes, I want to sample it again, but I cannot at the moment.

Here's an example of what I mean.

Here they take the scene color data, move it around on the horizontal axis, and then sum it all up. Then they take the sum result and do the same thing on the vertical. They are resampling modified data and not a raw asset. I would like shader forge to be able to do the same thing.
