Cases where severe issues are likely to occur, such as failure to upload, the model not displaying, the model not moving, or unintended behavior:
When the Clipping Mask reference is null:
- This occurs when the art mesh set as the Clipping ID is later deleted or hidden, causing the reference to become null. A warning message will appear in the bottom right of the editor in such cases.
- Review the Clipping Mask settings and ensure they are correct.
When necessary parts are exported while hidden:
- If the art mesh referenced as the Clipping ID is exported while hidden, the aforementioned issue will occur.
- Pay special attention to the hidden state of deformers. Even if it appears fine in the editor, it may not move or behave as intended when exported.
- Ensure that necessary parts are not hidden.
When pixelsPerUnit is not set to 220.20:
-If the pixelsPerUnit in the export settings is set to a value other than 220.20, the model will not display correctly on the screen.
When the values of Center of model X / Center of model Y are changed:
- If changed from the default value of 0.50, the center position of the model will shift, causing it to appear incorrectly in the app.
When IRIAM Parameter Settings are not set or are incorrect:
- If the IRIAM Parameter Settings are not set or are incorrect, the model's position, movement in all directions, and scaling will not function correctly in the app.
- Please refer to the relevant sections of the IRIAM Live2D guidelines.
Cases likely to cause the app to become slow or crash:
When the number of polygons in the art mesh is too high:
- The recommended number of polygons in the IRIAM Live2D guidelines is below 25,000.
- Exceeding this may cause the app to become slow or crash.
- You can check it at “Model Statistics” from the “File” menu on the menu bar.
When the number of divisions in the Warp Deformer is too high:
- The product of the Width and Height of the Warp Deformer’s ‘Number of conversion divisions’ exceeds 100.
- A warning message will appear in the Live2D Editor if such settings are applied.
When unused Warp Deformers or physics settings are left:
- Leaving such unnecessary settings can cause the model to become slow.
Other:
When there are overlaps or parts sticking out in the Texture Atlas arrangement:
- This can cause unintended parts to appear in unintended places or parts to be displayed incompletely.
When the tracking parameter settings are outside the IRIAM-supported values:
- For example, in IRIAM, the movement of the eyebrows is reflected by the combination of Brow Form -10 and Brow Y 0+1. Modeling beyond this range will not be reflected in the app, so caution is needed.
When special movements or physics gimmicks are set for IRIAM parameters:
- For example, setting shadows to appear on the face when the model is enlarged or hearts to appear in the eyes may not work as intended, so it is best to avoid such settings.
- Special gimmicks such as using physics to make something constantly rotate often do not work properly.
