I’m finally open for Live2D-style 3D hair physics comms on VGen!

#VGen #3DVtuber

[Rowan @RowanHeller]

Got it to work in vrchat

[Rowan @RowanHeller]

updated the shader, the vertex shader is perfect, the fragment shader not so much
#Unity

[Rowan @RowanHeller]

made a few tear meshes, the shapekeys look weird cause i grafted it and too lazy to tweak it

[Rowan @RowanHeller]

turns out vertex shader runs after skinning, so the displacement got messed up if the head is turned.
managed to salvage it by turning the deltas from object space to vertex space

Motion by 八ツ橋まろん

[Rowan @RowanHeller]

added toggle for additional parameter physics, tested on a bunch of animations, looks like for motions with a lot of head movement, it got drowned out, so there isnt much difference.
top : on, bottom : off

@peolle_artist I'm using a shader I made, it also uses extra data from custom textures

[Rowan @RowanHeller]

WIP tears
got it working in warudo

[Rowan @RowanHeller]

updates, added auto reinitialize so i dont have to manually do it, also found out how to get active camera

[Rowan @RowanHeller]

@V33_EX Thanks for the info! I have a better image now on what it would look like. i'll try experimenting with it and see how it looks.

[Rowan @RowanHeller]

using bone rotation, straight bangs becomes fragmented when it moves.
I wanted it to keep its shape, so i tried changing the physics from rotation to position.
it looks pretty good, but the threshold before it gets ugly is smaller than using rotation.
position <-> rotation

[Rowan @RowanHeller]

@V33_EX do you have any examples? im having trouble imagining this, do you mean using only one bone chain for the whole bangs, or make the bangs bones a child to a parent bone. if its the latter how does the physics work for the parent? also where is the parent bone placed?

Tears
too lazy to make the other side

[Rowan @RowanHeller]

WIP tears
finally got the shader to work

#Unity

[Rowan @RowanHeller]

@lynXYZart Thanks! vroid's presets are really good.

[Rowan @RowanHeller]

WIP tears
#blender

[Rowan @RowanHeller]

spent a few days converting from playground to plugins, finding out how to store the physics data was a pain.
also i cant find a flow output for on character change, so for now resetting is manual.

#Warudo

[Rowan @RowanHeller]

@AOKORODEV Thanks!

experimenting with scale
its fairly limiting since the bones are normalized
