Can't animate via World Position Offset when using Customized UVs

Hi everyone.

I’m trying to do some animation by scrolling a noise texture and setting its values to the World Position Offset input. The problem arises when, instead of scrolling the texture with the “UVs” input in the “Texture Sample”, I do it with a Customized UV0 input.

This is a basic example of what I want to do:

You can’t see it in a static image, but the problem is that the “Base Color” is actually animating correctly, but the vertex deformation isn’t. It applies some displacement, but like if the texture wasn’t scrolling, completely static. In fact, the preview in the texture sample isn’t animating either, even though I have enabled “Live Nodes” and “Live Update”.

However, when I connect those three bottom nodes to the “Texture Sample” node, everything animates correctly: the vertex offset, the node preview and the base color.

So I don’t know if it’s a bug or some limitation I’m not aware of.

Thanks for your attention!

I’m having this same problem as well. Is it that the vertex shader cannot have this feature?
