How is the Time slot in the time node used?

Hello, my question is as the title asks. I have been following this tutorial:

Making a Vertex Displacement Shader in Unity 2018.3! | Shader Graph

At around 3:38, it appears that by plugging the Time slot in the time node to a Simple Noise node, it creates a panning effect. However, that is not the case on my end. Doing that turns the Simple Noise node to pitch black for me. The other slots such as Sine Time and Cosine Time work fine.

Confirm that you have all your nodes hooked up in the correct slots? On 19.1.0f2 with package 5.13 I’m getting the expected behavior.

Yeah. Here, I used exactly the same nodes as you did. By the way, I should mention I am using LWRP, and I am sure I installed it correctly according to the tutorials. I am also using Unity 2019.1.0f2, but my Shader Graph is 5.7.2, which the Package Manager says it is up to date.

Seems to be working for me on Shader graph 5.13.

What happens if you connect the ‘add’ node to gradient noise? It should also give a moving noise effect.
And what happens if you connect Time to the noise output directly? (It flickers between gray tones for me)

Maybe try re-importing the packages in your project? I’m not able to reproduce this issue. I made a new project and stayed on 5.7 and I’m still getting expected behavior. If that still doesn’t work, try upgrading to 5.13 like so:

Thank you so much. Updating to 5.13 fixed it.
