Question 1
An FBX prop shades smoothly in Unity 2022.3 until its tangent-space normal map is enabled, when seams appear. The map was baked using MikkTSpace; the exported UVs and authored normals are unchanged. The texture is imported as a Normal Map, the model imports its normals, and its Tangents setting is None. What should the artist change before modifying the artwork?
Show answer & explanation
Correct answer: B - Calculate MikkTSpace tangents while retaining the imported normals.
