- Introduced the two-times upscale specification detailing requirements for unified output, fixed model presets, arbitrary dimensions, and consistent job behavior. - Added scenarios for existing models, repeated upscale, and handling of alpha preservation. - Created the unified depth plane specification outlining geometry modes, stable interface, and asset evaluation. - Defined scenarios for mode switching, relief and camera preservation, and validation of delivered assets.

Why
Tangent-space normal maps describe the full-depth surface. When a geometry node reduces its Depth Scale, its shape becomes flatter but the material normal remains at full strength, making surface detail appear too strong.
What Changes
- Reuse the existing
o_normal_reductiongeometry attribute as the material-to-geometry contract for tangent-space normal strength. - Make tangent-normal depth geometry write
1 - Depth Scaleto that attribute, so the material normal strength follows the displayed geometric depth. - Extend the existing
O Image Layerbehavior without changing its attribute lookup or fallback semantics. - Make Object Space normal strength follow the same geometry reduction contract.
- Reuse the existing
o_normal_reductioncontract for additional Tangent-normal depth geometry.
Capabilities
New Capabilities
depth-scaled-tangent-normals: Keep tangent-space material normal strength consistent with geometry depth scaling.
Modified Capabilities
None.
Impact
- Tangent-normal geometry-group builders, especially Relief Plane.
- Normal-scale node tests; saved node assets must be rebuilt with
uv run node-group build. - No server inference format, user-facing modifier socket, or dependency changes.
