UV Scrolling with HDRP Lit Shader

I've been playing around with the HD Render Pipeline, and I've been trying to figure out how to do basic UV scrolling with the default lit shader. Specifically, I'm looking to scroll the normal map, but accessing "_NormalMap"'s UV offset does nothing. It doesn't return any errors, but it also doesn't seem to do anything (note: I'm using a script that worked with the Standard Shader in Unity 5). Since it seems that the UV offset/tiling is shared between all of the base maps in this shader, is there some universal property that needs to be changed that I'm missing?

 

Is this with shader graph?

 

No, it's an external script based off of the old, old UV scroller script that used to be in the standard assets. Does shadergraph work with the HD render pipeline yet? That would solve all my problems if that were the case.

 

Yeah if you use package manager it automatically downloads behind the scenes. Just right click and create a new pbr shader and off you go.

 

I haven't been able to get shader graph to work with the HD pipeline. I'm using Unity 2018.1 and anything I create in it shows up as pink (somewhere I read it was compatible with the HD pipeline in the 2018.2 beta but haven't been able to find that again, is this true?).

However, I found the property I was looking for in my uv scroller script: _BaseColorMap. Scrolling that does the trick, at least until I can get shader graph working.


Update: I installed the latest beta and everything works with shadergraph. Neat!

 

@Ramandu - can you share what you wrote to actually offset the _BaseColorMap texture? Thanks a lot!

 

Code (CSharp):

1. public class CustomUVScroller : MonoBehaviour {
2.     public int materialIndex = 0;
3.     public Vector2 uvAnimationRate = new Vector2( 1.0f, 0.0f );
4.     public string textureName = "_BaseColorMap";
5.     public Renderer render;
6.     Vector2 uvOffset = Vector2.zero;
7.     void Update()
8.     {
9.         uvOffset = ( uvAnimationRate * Time.time );
10.         if( render.enabled )
11.         {
12.             render.materials[ materialIndex ].SetTextureOffset( textureName, uvOffset );
13.         }
14.     }
15. }

I would recommend implementing a UV scroller in Shader Graph (or Amplify Shader Editor) instead, though, as that's a much more versatile (and better performing) solution. I no longer use the code above for that reason; it was merely a workaround until I got Shader Graph up and running.

 

Thanks a lot. I will work on the shader graph also - i actually thought that it was not more optimized to use shader graph - compared to using the lit shader... - but that is great - because the shader graph is much more fun.
