DeepSkin V6 - Transparency & Hide Skin Under Clothing
This update brings built-in transparency in DeepSkin. With transparency in DeepSkin's shader, it also allowed me to build an experimental system for hiding skin under clothing to minimize clipping.
(Many people have requested compatibility with mopedlampe 's newest 2B model, which is now fully compatible.)
NEW: TRANSPARENCY
Built-in transparency, found in the new "Fade" tab. Unlike transparency plugins that swap the skin to a stock transparency shader and lose the shading, transparency now happens inside DeepSkin's own skin shader: SSS, transmission, wetness and shadows all fade down together with the skin.
Global Transparency, six Group Masters (Face, Torso, Limbs, Hands, Feet, Eyes) and per-part sliders. Every slider is a plugin storable, so Timeline can animate them.
Alpha Masks (Face, Torso, Limbs, Genitals) allow you to load custom alpha textures just like other transparency plugins.
Fade Shadows: gradually fades the shadows as the skin is fading. Shadow Hold keeps the shadows stronger deeper into the fade, Keep Shadows Below sets the cut point when Fade Shadows is off.
Dissolve Style: a special effect for the skin fading. A continuous noise pattern across the body with glowing edges. (as seen in the GIF above)
Render Queue slider
'Show Fade Masks (debug)' makes transparent skin red for checking masks and coverage.
NEW: HIDE SKIN UNDER CLOTHING [experimental]
Found in the "Clothing Tab":
When toggled on, skin under a clothing gets hidden, which helps prevent clipping of skin through clothing.
Toggle per clothing item: "Hide Skin Under Item". DeepSkin automatically maps the skin covered by the clothing item and 'paints' it hidden.
Clothing Depth Guard: a per-pixel test that only shows skin sitting in front of the fabric on screen. Guard Bias sets how far skin may show in front of the clothing before it shows; Soft Body Guard Bias is a higher value and applies over the breasts and glutes, since those areas tend to clip the most.
Auto Reveal When Cloth Moves: a system where hidden skin shows again wherever its fabric is no longer covering it, so a towel or robe being dropped will dynamically un-hide the skin. For clothing items that cover most of the skin and aren't supposed to come off (like bodysuits, t-shirts), I recommend turning off auto-reveal so the skin will always stay hidden.
Paint Hidden Skin for manual refinement: paint the skin that should be hidden, or erase to keep those areas always visible. Paint saves per item and reloads next time you equip the clothing item.
Known limitations:
- The depth guard makes auto-reveal possible, but extreme movement can still show brief clipping at grazing angles.
- Clothing that have see-through parts will not show skin below it (because it's hidden).
- Mirrors use the proximity field only, so clipping will still show on mirrors.
- The automatic bake is taken at the pose you enable it in. Toggle the item off and on to bake again.
FIXES:
Clothing
The per-item settings on the Clothing tab (Include In SSS Blur, Hide Skin Under Item, shadow fade opt-outs) now save with the scene, not just in presets.
Mouth
Fixed the mouth shadow lagging behind head movement and darkening the teeth mid-motion.
Lip shadows are now per jaw: the lower lip no longer darkens the upper teeth in smiles and lip bites, and vice versa.
Skin
Fixed the Skin Gloss slider doing nothing under exclusively VaM global lighting.
