First ScalaOp after time input is to modulate time(speed control) the second one after the sinewave is to modulate the sinewaves amplitude.

That's a great starting point. As it is right now however, it is just moving texture side by side. To make it wavy, you should add an offset to the sine along with TIME. In this case you could add the UV's y component to it, multiplied by a variable number to determine it's frequency.

thanks guys(I assume you are men :) ) I will plug it all up in a few minutes...just rolled out of bed :) EDIT: set it up, just swapped the x,y because I am scrolling in the other coord...but everything is working...thanks.

double edit: first sorry, I couldn't edit my previos post...don't know why.

but upon closer inspection(after coffee) I realized that it is not scrolling but stretching or oscillating ...I know it's the sin function/operation but I just want it to scroll...I could use it like this, but would prefer it to simply scroll. Not that I don't appreciate the help.

I think there might be a time limit for how long you can actually edit your posts as a user, might have been 1h.

You likely have used a Multiplication ScalarOp instead of an Addition then for the third Scalar Op. Look at my image above again.

Or do you mean that it's ping-ponging/swaying back and forth? if that is what you mean then yeah, you can just cut the Sinewave ScalarFunc and the following Mult ScalarOp out to remove the sway.

ok. yes, that is the case so.....I went out of time(node/output) to a scalar(divide/to slow it) and then into the vector compose and that works...thank you very much.

simpler version

it scrolls vertically, but how do you scroll horizontally? Connect ScalarOp to x on VectorCompose and disconnect Y input You can change the speed by changing the value of the Multiply node (ScalarOp), this scrolls backwards, you can scroll forward by changing the value to negative

Yes, thank you..I already did all that...it was easy to figure out.... Still it's good to have reference here on the forum if anyone searches for it.

I am having a problem with creating a scroll shader that doesn't seem to be addressed by above. I attached two images to show the problem. Adjusting UV on the texture is not functioning as I expected.

The UV doesn't look right... Have you tried attaching the UV input directly to the texture and see what happens?

Edit: No wait! I think it might be the texture itself. Have you enabled repeat on the texture?

Make sure your texture(in the import settings) is repeatable.
