1️⃣ Learn what clipping is and how it works in Live2D Cubism
2️⃣ Learn how to apply clipping between Art Meshes
3️⃣ Clip all the required parts in the Lua model correctly
🚩 Quest 1: Learn what clipping is, and try clipping two Art Meshes together
🚩 Quest 2: Clip the Art Meshes required on the Lua Model
Clipping allows you to "mask" or hide an Art Mesh based on the shape of another Art Mesh, which acts as the clipping mask.
When clipped, the visible part of an Art Mesh will only appear inside the boundaries of the mask.
An Art Mesh is a single art layer of the model that has a mesh drawn on top of it for deformation, animation, and movement.
So when we say "Art Mesh," we’re referring to both the art and its editable mesh.

Level 1 - Stage 1 | Clipping Study File
You’ll see two Art Meshes: the Protagonist Logo and a Purple Circle.
"Circle", the ID is also "Circle".
"Artmesh#" if your layer names have spaces. To avoid this, name your PSD layers with underscores instead of spaces (e.g., Mouth_line instead of Mouth line)."Circle")."Protagonist Logo").
✅ The Protagonist Logo will now be clipped to the circle, and will now only appear inside the mask’s shape.
Want the Art Mesh to appear only outside the mask?
Enable Invert Mask in the Inspector Window. This makes the clipped art show only outside the masked area.
When you first import the Lua model, you’ll notice it looks a little strange. That’s because nothing is clipped yet.
To clean this up, we need to clip the correct parts of the model together.
For Lua’s model, let’s start with an easy one:
Lua_Faye_VTuber_Model > Chest
"Badge_" Art Meshes
✅ All Badge parts are now clipped cleanly to the mask.
You can now clip the rest of the model using this checklist:
Head_Shading → clip to Head_ColourNeck_Shadow → clip to NeckLeft Eye:
Eye_Highlight_Left_(1–4)Eye_White_Shadow_LeftIris_Lines_Left, Pupil_Left, Pupil_Shadow_LeftEyeball_Lines_Left, Iris_Blob_Left, Iris_Colour_Left, Iris_Glow_LeftEye_White_LeftRight Eye:

Leg_Metal_Loop_Highlight_Left → clip to Leg_Metal_Loop_Base_LeftLeg_Metal_Loop_Highlight_Right → clip to Leg_Metal_Loop_Base_RightEarring:
Earring_Highlight → clip to Earring_ColourTake your time working through this list—you can select multiple Art Meshes at once to apply the same Clipping ID in one go!
If parts still look off, make sure your clipping IDs are correct and that you’ve selected the right mask.
Use the Parts Window and Inspector Window together to double-check names and IDs.
