These are underfill layers! They are a solid color layer underneath another color layer, but they are slightly bigger, making it look like the outline of the layer above. This method will make it easier for riggers to give the model more range, as the underfill is easy to adjust

I used this for the body skin layers only. All other layers dont have underfill. The body needs the most angles and physic parameters for my rigs, so having underfill makes it a million times easier for me to get wide and smooth angles compared to normal layers!

I will release a free PSD study for live2d artists on how to set up these layers on body skin parts soon! Feel free to send those to your live2d artists if you are a client looking to commission a model as well! your rigger will absolutely LOVE YOU ✨

heres an example video by cillia that breaks down the different layers! Ive seen her talk about underfill for a while but only just had a chance to try it out for myself and its a game changer! 🥰

@_suiika_ OOOOOO So it basically mimics the line work layer by being slightly bigger then the base skin layer. So you wouldn't have your linework attached to the body parts itself? I think I got that right? I'm about to start learning Live2D so I am living for this tutorial. Thank you! <3

yes, exactly! you will still need some lineworks, but the underfill will take care of all of the main outline! good luck on learning! its worth it in the end :3

@_suiika_ We love when experienced artist and riggers don’t gatekeep knowledge!! Thank you so much for this I have 3 models I’m working on and this would be nice practice

@_suiika_ when the art has these + a third “texture” layer thats wider that both so it can get clipped to the solid color layer then rotated when the body moves 🤌

@_suiika_ oh this is how I do some of my model "line art" hehe

@_suiika_ I think this is way better to do the body angles with !

@_suiika_ Daaamn dude! you really have improved alot!! its honestly been awhile I've seen your work on my feed and awesome to see it again 💪
