| Jan 26, 2023 at 1:18 | comment | added | Path11 Media | I figured it out. at the end of your string, above the Mix Shader, I set the Attribute input above the Mix Shader, ran you r mix Shader into another Mix Shader with the Attribute of the Vertex Group as the factor and your shader and the main BSDF Shader I had as the two shaders in the last mix, then out to the Material Output. Thanks for getting me on the right path, I hadn't used mixed shaders that much and it was off to the side of my thinking...your tip opened my mind up. | |

| Jan 26, 2023 at 1:14 | comment | added | Christopher Bennett | If you just want to overlay the "Freckles" over another color (or image), you can use the ColorRamp as a fix factor for a Color Mix node between your freckle color and whatever other color/image you're using, then feed that either directly into the output (unshaded), or use the color mix as the BaseColor for any BSDF. I'll update my answer with an example. | |
| Jan 26, 2023 at 1:01 | comment | added | Path11 Media | Hmmm, no, ran into an issue, looks good the way you have it but, mine feeds back into the mixers above that are carrying the rest of the skin colors. Each has an input Attribute node that specifies the appropriate vertex group lips, eye rim, etc). the string you have ends in BSDF's and I can't get the Attribute input specifying the Freckle vertex group plugged into this. I'll work on it. | |
| Jan 26, 2023 at 0:15 | comment | added | Path11 Media | Ah! That works great! Thanks. I wanted to keep it procedural with the mapping nodes because I can easily slide the field in any direction if I don't like the layout, or adjust the size to be blemishes/marks on a creature or animal. And yes, I'm using EEVEE. | |
