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 a 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!
Are you sure the robot from the Adam project was using the standard HDRP lit shader, and not some custom shader that the Adam team made themselves? Often with those tech demos, they push the limits of HDRP, and tend to use custom shaders rather than just the Lit shader. You’d have to look at the sample project in its entirety, rather than just importing the single model into a new project, to be sure.
It sound sound like you’re looking at a spec/gloss map, maybe. The Lit shader supports a specular workflow by setting the Material Type, but I wouldn’t be able to say whether the texture you’re looking at is fit for that purpose.
Mostly I’d recommend trying to make sure you download a complete demo project. And if it’s one of Unity’s annual tech demos (like Adam, or Heretic, or Enemies) be aware that those will be full of non-standard, custom shaders and approaches, which really aren’t a great place to start to understand how basic HDRP works. For that, I’d probably just go with the standard HDRP template scene you can find in Unity Hub when creating a new HDRP project.
Hey thanks for the reply. I think you are spot on here, it seems like several of the materials used a custom shader for sure. I’m trying to play around with the hdrp lit shader to mimic what I see in the adam movie to get it atleast looking similar. I downloaded the single model off Git, there is another supposed sample scene that I might be downloading wrong or something but when I try to download the whole demo scene the folder has a bunch of nonsense in it with no scene or 3d models. I just started using git so maybe im doin it wrong. Unity doesnt offer adam on the asset store anymore so Ive just been messin with the single model, enabled the specular setup like you mentioned and played with the settings a bit and got a pretty good result so far with that sg map, its not perfect though. Having issues with the eyes, they were definitely a custom shader. Think I have the two eye structures set to translucient and transparent and they each just have a simple base color, looks ok for my learning purposes. I gotta figure out how to use the emission property as well for the monitor screen on his chest, no clue how to mimic a glass glowing screen really. I’ll post a few pics with settings if it helps anybody else tinkering with this sort of thing. Any suggestions for settings for eyes and the computer screen on his chest?
**Also I’ll post the SG texture in the morning if that helps figure out what it is? **
