Fade effect for specular map
Hi
I'm still learning Photoshop and I'm currently trying to make a specular map for a 3D model in Blender as part of a guide I'm following. I have the reference texture the author made, which I'm trying to replicate, but I can't seem to do what the creator's done for the specularity of the lips. I've tried messing with the opacity by lowering it 25% for each stroke, but it's giving me undesirable effects. I've attached an image of the desired effect I'm after. The colour blends and fades perfectly.
