Trouble Diffuse Texture not Showing in Render

So I created this simple Shurb using the Sculpt Tool then used diffuse texture and then a colour ramp to create the result you see here.

However when I go into render mode, the material is not showing, only a green base.

Is there anything I’m missing I need to click to show up in the rendering? or is it a lighting issue? Help is much appreciated! Thanks!

perhaps it is just too dark? your light is turned off!

Otherwise:

Add lights , there is no lighting in ur scene. Mat prev is lit by a default hdri , so u can see the textures.

Your light is disabled in the Render Mode.
Without an light or an hdri there won’t be any color difference with a diffuse shader. In Material Preview Mode there is automatically an hdri.
