Upgrading Custom Lighting Function to urp 10.0

Hello,

Could someone help me upgrade the custom lighting function in this tutorial?

To URP 10+. I get the error #if SHADERGRAPH_PREVIEW is an invalid conditional expression

Also if anyone could point me in the direction where I could learn more it would be greatly appreciated

Changing #if to #ifdef fixed it for me

How we built the toon shading | Open Projects Devlog - YouTube there is a new version of the node in this official video from unity

@aushy1 sorry, but did you fix it? i have the same
