HDRP Lit shader textures

Hey guys, I’m new to hdrp and have been away from unity for a while. I recently imported the Adam robot character and I’m trying to assign the correct textures to materials using the HDRP Lit shader. Lets start with the fact that there is an sg texture in the folder…What is an SG map? Where do I assign it on the hdrp lit shader? Id guess its specular but I’ve never seen a texture map labeled sg before. I have a few other questions but lets start there. If this post is in the wrong place my bad. Thanks!

If anyone comes across this, the sg map looks pretty good in the specular option so hopefully that’s where it goes
