BlenderMCP

Feature: Seams and Shading Helpers As a retopology artist I want to mark seams and sharp edges automatically So that I can prepare meshes for UV unwrapping and proper shading Background: Given the MCP server is running And the Blender addon is connected And a mesh object is active Scenario: Mark UV seams by angle Given a mesh with no UV seams When I call mark_seams_by_angle with angle=60 Then edges with angle ≥60° become UV seams And the seams are ready for UV unwrapping And the seam count is returned Scenario Outline: Mark seams with different thresholds Given a mesh with varying edge angles When I call mark_seams_by_angle with angle=<threshold> Then <expected_behavior> edges are marked as seams Examples: | threshold | expected_behavior | | 30 | many sharp and moderate | | 60 | only sharp corners | | 90 | only perpendicular edges | Scenario: Mark sharp edges by angle Given a mesh with smooth shading When I call mark_sharp_by_angle with angle=45 Then edges with angle ≥45° are marked sharp And the shading respects the sharp edges And the edge count is returned Scenario: Mark sharp edges for better shading Given a hard-surface model with smooth shading When I call mark_sharp_by_angle with angle=30 Then the model displays proper hard-surface shading And edges look crisp without artifacts Scenario: Clear existing seams before marking new ones Given a mesh with existing seams When I call mark_seams_by_angle with clear_existing=true Then old seams are cleared And new seams are marked based on angle
