They don't move by default, but you could weight them to some bones if you'd like them to be able to move.

are the eyebrows supposed to move at all, and if so, how

Yo I hate to bother but, is there also a skin node setup im just not seeing

eyes setup - EYES SETUP
hlt setup - HLT SETUP

Apologies to anyone inconvenienced.

@T0biasCZe
Um, I guess you haven't heard. Jasper deleted his discord account. The links don't work because he posted them. I'm sorry for the inconvenience, but I can't do much of anything about it.

@jasper7438 the images you send dont work anymore (the node setup for eyes, and then for the HLT node setup)

Okay... This is my final question about the textures. You don't have to respond. I don't wish to be a bother, but I ran into a problem with applying the mlta or mltb textures (especially to jellyfish). I tried a lot of methods, but I got lost. This is the last time I will ask about the textures, because I am kind of a noob to using the node editor in Blender. I hope this isn't a bother.

@Jasper Thank you! Sorry for bother you about this. These textures were always bugging me when applying them. Thanks for your help.

I have a HLT setup that works pretty well, here is the node setup for it.

As for RFT [Lightwarp], I haven't really found a setup yet. You can try using/messing with the HLT setup.

FXM [Effect maps] are for Splatoon shader effects and change depending on the material. That means that most of the time they have no compatible use in Blender...
The only ones I use are the ones for the Squid sister outfits, I use them as Fac for the HLT texture plugged into a Layerweight node, here's what that setup looks like.

Aside from that, if you aren't already, mess around with the other Principled shader values such as Specular and Clearcoat, I've found that they can make the material look more like the game/less flat.

Wish I could've helped you more! ~ Jasper

@Jasper Yep! That really helped. Thank you for the setup, and information about the maps. But I also haven't found solutions for other map setups: htl maps, rft maps, fxm maps. Do you have any references or information you can share about how to apply those? If not, it's okay.

@Scolipedeking + Anyone else having trouble with the body textures

Here is a picture of the node setup

Hope that helps! ~ Jasper

By any chance, does anyone know how to properly apply the skin textures shown in the render above? If so, an example of the nodes would be nice. I came close to a process, but I hit some obscure block that I can't seem to get over when it comes to skin tone and applying the trm texture.

If no one knows, that's okay. It was worth a shot. I'm using Blender 2.82 by the way.

@GregoryTheGamer I think those would have to be parented using a modifier I think. I have tried something similar with a phone model, and I modified it to be parented to a certain bone on the other model.

Is there a way to rig up the separate parts (Like Hair and Pants) to the main model properly in Blender?

@Jasper7438 Yep. Thanks for that. All I have to do is get rid of that blue tint that appears when I turn up the Subsurface Scattering.

Thanks, I separate the mouth from the teeth.

The mouths are weird [they don't seem to have textures, maybe the teamcolor texture applies to them..?] What I do is separate the teeth from the mouth, apply the eyebrow material to the inside of the mouth [minus nrm texture], and keep the teeth the default material. There might be a correct way to do it, but I don't know it. ¯_(ツ)_/¯

Scratch that, I'm not sure. You could try selecting the teeth in edit mode, then applying a separate material to them.

Are you using a mix blend mode on your mix RGB node, or multiply? That might be the problem. Plus, make sure you are coloring the .tcl texture, and adding it to the albedo texture.

(Hi again) I have issues with teeth on blender, i don't know how to have white teeth with a colored tongue/mouth.
