I can't seem to find these two “S” and “T” coordinate options in the texture node inside Attribute Vop in H16. Anyone knows why or what have they been changed to? https://imgur.com/a/LNjMa [imgur.com]

From the image, it looks like they were replaced with uv, and that dsand dtwere replaced with duv. I don't know why they would have been sand tbefore, since it's uveverywhere else in Houdini, but maybe they had subtly different meaning or something like that. (or maybe there was some other reason I'm not aware of for naming them that way before.)

The tutorial that i checked had the s and t in the video and also in the files provided. I am kind of stuck over here and can't advance further without solving this error.

If you have separate uand vvalues, you can combine the incoming values into a single uvvector using the Float to Vector VOP, and plug the output of that into the uvinput.
