How to create a gradient animation with Shader Graphs

[deadl]

Hey guys.
I want some tips on how to create a gradient animation like the image below without using a 2d texture but only using nodes this way I can change the color.

Thanks

wow, Sorry, that’s a MUCH bigger problem then I initially recognized! I am stumped

there is a gradient node that lets you build colors like that (limited to 8 colors, you’d have to combine multiple for more)
then sample gradient to accept it as color output

if you need a strob, take fraction of time to loop it

as for a gradient scrolling that is a much bigger challenge trying to account for a range
Unfortunately Gradient is not exposed on my URP material so there is no way to set it on material

it looks like you make multiple color node properties but you’d be limited to a static number of colors
how to expose an input to construct the number of colors to make it dynamic? that’s way over my head

thanks for the help.
I was really looking for the scrolling effects . I think will stay with the 2d texture method

If I not misunderstand the scrolling effect is not that hard when you have your gradient.
You just need to had an Tilling node and use the R or G factor as your Time property. Fraction it before to make it loop between 0 and 1 .
Next you can apply the scroll at your UV exactly like with your sample texture.

PS: Switch gradient from Blend to Fixed to obtain fixed color instead of gradient between color.

OH brilliant! you can supply a range from 0-1 just like a LUT

this could be any gradient but a UV node (tiling) already has a vector2 of that!

PS: Switch gradient from Blend to Fixed to obtain fixed color instead of gradient between color.

you could Posterize the tile/UV node (supply vector so material = # of steps) or even the gradient to continue to have blended colors and get material defined steps
