In 3D and AI animation, two faces touching is a nightmare. Usually, the noses clip through each other, or the lips meld into a single terrifying mouth. Generating a passionate, open-mouthed kiss that looks human is incredibly difficult.

The WAN 2.2 Kissing Workflow solves the Mesh Collision Problem. Instead of relying on the base model (which gets confused by two faces this close), it utilizes a “Dual-Stack” LoRA technique. By analyzing the node graph, we can see it applies the kissing motion logic twice in the generation pipeline, creating a reinforced “contact zone” where lips meet but don't merge.

🛠 The Technical Breakdown

This workflow is heavier than the others because it prioritizes geometry over speed.

• The “Dual-Stack” Engine: This is the secret sauce. It loads the KISSHIGH and KISSLOW LoRAs twice. First at 0.3 strength (Nodes 142/143), and then again at 0.6 strength (Nodes 170/171). This layering effect forces the AI to pay extreme attention to the boundary between the two faces.

• Midnight Flirt Base: It runs on the dasiwaWAN22I2V14B_midnightflirt checkpoint (Nodes 168 & 169). This model handles skin-to-skin lighting better than the standard Wan 2.2, which is crucial when two faces are casting shadows on each other.

• Tongue Physics: The prompt includes french kiss, which combined with the LoRA stack, allows for “Tongue Interaction” (the hardest physics to get right) without the AI deleting one of the tongues.

📝 How to Use This Workflow

1. Input Image: The source image MUST show two faces close together. Ideally, they should be nearly touching. If you use a photo of two people standing 3 feet apart, the AI will warp their necks unnaturally to make them kiss.

2. Prompting: Keep it simple. kissing, making out, tongue. If you add too much background detail, the AI will lose focus on the delicate lip connection.

3. Face Restoration: This workflow relies heavily on ReActor (Node 166). Because kissing distorts the jawline, the face restorer is essential to keep the non-kissing parts of the face (eyes, nose) looking recognizable.
