For users with texture quality issues, here's some advice to improve scan data texture quality:
- Ensure that you perform texture mapping after meshing the scan data. Without texture mapping, the color texture is displayed on the mesh vertex. After mapping, the users obtain a high-resolution texture image mapped to the model.
- On PC software, EXScan Libre, when you mesh the model, the default setting is also mesh without texture mapping. For high-quality texture, please turn it on or do texture mapping later.
- As an optical scanner, it has a specific best focus distance at which it can capture the sharpest scan data. For the HD laser mode, the optimal distance is approximately 300 mm, whereas for the IR rapid mode, the recommended distance is around 800 mm.
- An incorrect white balance will lead to color shifts, while improper brightness can result in overexposure or underexposure of textures. Check the texture camera's brightness settings and readjust the white balance if the ambient light conditions have changed. To access the texture camera settings, click on the brightness icon on the right, then switch to the texture camera by clicking the ball on the bottom left of the camera window.
- To achieve a uniform texture, it's crucial to maintain consistent external lighting conditions. Single-sided lighting can result in one side being overexposed while the other remains dark. For outdoor scanning, the user may attempt to adjust the texture camera's brightness when moving between different lighting areas.
