Issue Description
The “Question Mark” accessory has a problem with its mesh rendering. The triangles of the mesh create odd points in the middle of some faces. This issue stems from older rendering formats, making the topology appear strange and uneven. Attempts to fix this in Blender by converting triangles to quads or modifying the shading (smooth or flat) do not resolve the issue.
After some research, I discovered a solution online related to smoothing normals and topology adjustments, which significantly improved the accessory’s appearance without altering its design.
Reproduction Steps
- Import the “Question Mark” accessory into Blender or another 3D editing tool.
- Inspect the mesh topology, noting the odd points forming in the middle of some triangular faces.
- Attempt the following fixes:
3.1. Transform triangles to quads.
3.2. Apply smooth or flat shading. - Observe that these fixes fail to resolve the issue.
Expected Behavior
The “Question Mark” accessory mesh should appear smooth and consistent, with no irregular points or distortions on its surface.
Actual Behavior
The accessory’s mesh displays uneven topology, with points forming in the middle of triangular faces. These distortions persist regardless of shading adjustments or triangle-to-quad transformations.
Solution:
To resolve this issue:
- In Blender, check the Auto Smooth box. Use a threshold angle of 30 degrees or adjust as needed.
- Optionally, apply a Decimate Modifier in Unsubdivide mode with 2 iterations. This smooths the topology without drastically altering the design.
