Hi friends,
I just moved to URP and I got some problems with a few shader 
I’m noob in this aspect can I convert my previos shader to URP? Thanks in advance!
Shader 1:
Shader "Paint/MetalURPTest" {
Properties {
_Color ("Main Color", Color) = (1,1,1,1)
_Detail ("Detail Texture", 2D) = "black" {}
_SpecularMap("Specular Map", 2D) = "white" {}
_Cube ("Cubemap", CUBE) = "" {}
_BumpMap ("Bumpmap (RGB Trans)", 2D) = "bump" {}
_Reflection ("Reflection", Range(0, 1)) = 0.5
_SpecColor ("Specular Color", Color) = (0.5,0.5,0.5,1)
_Shininess ("Shininess", Range (0.01, 1)) = 0.078125
_RimPower ("Rim Power", Range(0.5,8.0)) = 3.0
}
