1. Hair looks very flat after converting to Hair Cards. How can I improve this?

Hair cards simulate hair using texture projections, which can look flatter than particle hair. To enhance depth and realism:

• Increase hair density when generating textures (adjust "Number");
• Add random variations in length, rotation, and distortion in the Hair Card settings;
• Use Clumping to create more natural, complex shapes;
• Avoid overly dense textures—leave gaps to add layering and dimension.

2. The hair card mesh has millions of faces—how can I optimize it?

Too many cards or overly dense textures can cause mesh bloat. Try:

• Reducing the total number of cards;
• Increasing hair strands per texture;
• Using LOD (Level of Detail) to generate simplified versions for export;
• Keeping texture resolution within reasonable limits (e.g., 2K/4K).

3. Hair card textures appear black or materials don’t show—what should I do?

Possible causes:

• The hair layer had no material assigned, so the texture wasn’t generated;
• File path issues or permission restrictions (common on Windows);
• Incomplete material node setup, especially Alpha not connected properly.

Check the material setup and test visibility in Render view. If the issue persists, refer to the provided screenshot guide.

4. Blender crashes or freezes during Hair Card conversion. Is this a bug?

It’s usually not a bug. Most crashes are due to too many hair guides or not using children, causing heavy performance load. The add-on generates cards based on hair guides. Recommendations:

• Use children hairs instead of manually grooming all guides;
• Reduce the number of hair strands in the conversion area;
• Convert in batches to avoid overload.

5. Can hair curves be converted to hair cards?

Currently, hair card functionality only supports particle hair systems. For hair created with Geometry Nodes or Curve Hair, convert it to particles first before using the card system.
