ComfyUI Game Assets Maker

Custom ComfyUI nodes for game asset preparation workflows.

Nodes

SeeThrough Parts To SVG Paths

Converts SEETHROUGH_PARTS from SeeThrough_PostProcess into SVG path outlines.

The node traces each part's alpha mask, optionally preserves internal holes with hierarchy mode, orders parts by depth_median, and can save the generated SVG to ComfyUI's output directory.

The first output is a ComfyUI SVG-compatible object and can be connected directly to the built-in Save SVG node. The second output is the same SVG as text for inspection, and the third is the path written by this node when save_svg is enabled.

It intentionally ignores source colors and textures. The output is vector tracing of layer silhouettes only.

SeeThrough Parts Rig Probe

Tests whether SEETHROUGH_PARTS tags are useful enough to seed a 2D rig.

The node reads each part tag, estimates semantic role and side, calculates alpha-based bounds, pivots, and a simple bone hierarchy, then returns GAME_ASSET_RIG, editable JSON, and a text report.

Use the report output to inspect whether tags like left_arm, head, torso, right_hand, or similar names are being classified correctly before building a full interactive rig editor.

Apply Rig Overrides

Applies manual JSON edits to a GAME_ASSET_RIG while preserving the generated structure.

Override parts by id, tag, or tag:<exact tag>, and override bones by bone id:

{
	"parts": {
		"face": { "pivot": [653, 650] },
		"tag:front hair": { "pivot": [704, 526] }
	},
	"bones": {
		"face_bone": { "parent": "neck_bone" }
	}
}

The node returns the adjusted GAME_ASSET_RIG, updated JSON, and a report of what changed.

SeeThrough Parts Pose Rig

Builds a GAME_ASSET_RIG from SEETHROUGH_PARTS plus POSE_KEYPOINT from DWPose Estimator or OpenPose Pose in comfyui_controlnet_aux.

Recommended wiring:

image -> DWPose Estimator.pose_kps
SeeThrough_PostProcess.parts -> SeeThrough Parts Pose Rig.parts
DWPose Estimator.pose_kps -> SeeThrough Parts Pose Rig.pose_kps
SeeThrough Parts Pose Rig.rig -> Rig To SVG Preview.rig

The node first creates the same automatic tag/bounds rig as SeeThrough Parts Rig Probe, then replaces pivots with pose keypoints when available. Missing keypoints fall back to the automatic pivot.

Current pose mapping:

face/head -> neck
neck -> neck
nose -> nose
mouth -> mouth landmarks
eye left/right -> left_eye/right_eye
upper_arm -> shoulder
forearm -> elbow
hand -> wrist
thigh -> hip
calf -> knee
foot -> ankle

The report output lists how many pivots came from pose data and which parts used fallback.

Rig To SVG Preview

Renders a GAME_ASSET_RIG as an SVG overlay with bounds, bones, pivots, and optional labels. The first output can connect directly to ComfyUI's built-in Save SVG node.

Rig To Spine Export

Exports SEETHROUGH_PARTS plus a GAME_ASSET_RIG as a Spine-style region attachment package.

Recommended wiring:

SeeThrough_PostProcess.parts -> Rig To Spine Export.parts
SeeThrough Parts Pose Rig.rig -> Rig To Spine Export.rig

The node writes a timestamped folder under ComfyUI's output directory:

game_asset_spine_YYYYmmdd_HHMMSS_xxxxxxxx/
	game_asset_spine_YYYYmmdd_HHMMSS_xxxxxxxx.json
	game_asset_spine_YYYYmmdd_HHMMSS_xxxxxxxx.atlas
	images/
		face.png
		front-hair.png
		topwear.png

Each SeeThrough part becomes a PNG region attachment. Rig bones become Spine bones, slots preserve the rig part order, and image-space Y coordinates are converted to Spine's Y-up coordinates. Exported bones include length and setup rotation derived from the rig head/tail points, while attachments are counter-rotated in local space so the assembled character stays aligned on import.

Common semantic parts get a minimal control hierarchy before export. Body/topwear and face become structural controls; hair, iris, and eyelashes become point controls for sway, eye movement, and blinking. Static details like legwear, footwear, ears, brows, nose, mouth, neck, and handwear remain as attachments mapped to the nearest useful control instead of creating extra bones. Attachment paths use the region name, such as face, while atlas pages point to files such as images/face.png.

After the node runs, use the Download Spine ZIP button on the node to download the generated JSON, atlas, and image folder as a single archive.

Automatic animation controls:

animation_preset: all / full_idle / idle_breath / blink / hair_sway / face_alive / no_animations
animation_duration: loop length in seconds
animation_intensity: transform strength multiplier
blink_interval: seconds between blinks

The default all preset writes separate idle_breath, blink, hair_sway, and face_alive animations, plus a combined loop named idle. These animations use bone transforms only, so they work with the region attachments generated by this MVP exporter.

This is an MVP region-attachment export, not a mesh/skinning export yet. It is intended as a starting point for importing and refining in Spine.
