Question Can you set vertex color from shader graph?

There doesn't appear to be an option to set vertex color in shader graph, am I missing something?



I ask this because I am trying to convert a surface shader I had written to shader graph so it will work with HDRP.

Any help is appreciated!

 

Yes and no.

You can’t set the vertex color, no. But you can pass a custom interpolator per vertex to the fragment, if you’re using Shader Graph 12.0 or newer.

Thanks! This works perfectly for what I need.

 

Sorry for bringing this up again - but i want to set Vertex Colors as well and it seems like i may misunderstand the whole concept of the interpolators. What i want is old school vertex lightning on some of my objects. I want to have this smooth color change between two vertices just like if i would paint the color in iE Blender and then use the Vertex Color node of Shader Graph. Is there a way to achieve this ?
