 So I've been a little hesitant to show you guys this technique because it's not really industry standard and it's probably not recommended but when I'm making game characters it's just super fast and easy and it adds zero extra polygons to my computer's stress and it's been really useful for me so I'll just share it with you. If you have a black and white image of an eyebrow design from Photoshop or ZBrush or whatever art software you like you can literally just add a paint layer and drag the black and white map into your alpha and set the settings and color however you need to just plaster them straight onto your character. Now this is cool but if you have real hair cards obviously it'll look a lot better because then you can also drag the normal map and the color map to get even more detail but really especially for game design the alphas are pretty much all you need and like I said you can use any generic black and white eyebrow alpha. Now if you don't have your own eyebrow hair cards and you don't feel like going into a software like photoshop and making them you can go get mine from artstation. I have a pack that just has a pack of 20 different eyebrow textures that I use for all my characters and each of them has their own fiber card and all of the texture maps needed to bring out the tiny details. This includes things like the albedo, the alpha, the normal, the height, the occlusion, everything. Once you have the maps you can easily drag the color, the normal and the alpha into substance, set them to texture, alpha and texture, then set it to current project, then just go to your generic brush, drag in the alpha, drag in the color, drag in the normal, then right click, create tool, right click, give it a name and now every time you open substance painter anytime you want to plop some fast eyebrows to your character just go to your tool and left click where you want the brows to be and you can do this for all the different eyebrow designs you have. So when I open substance and I need eyebrows I just pick from my 20 eyebrow tools to get what I want but yeah that's how I do eyebrows so I hope that helps and as always hope you have a fantastic day and I'll see you around.
