This LoRA creates a complete horizontal 6×3 facial reference sheet containing eighteen portrait panels of the same character.
The character’s identity, appearance, clothing, rendering style, lighting, camera distance, and background remain consistent across the entire sheet.
Only the head angle, eye-gaze direction, and facial expression change.

Important Resolution Information
The most reliable base resolution is exactly:
1672 × 944 pixels
This resolution reproduces the intended 6×3 arrangement most consistently.
The LoRA has learned not only the expressions and viewing angles, but also the spatial structure of the complete sheet. Changing the width-to-height relationship can therefore affect the layout.
A canvas that is too wide may cause the model to generate additional rows, columns, or portrait panels.
A canvas that is too narrow may cause panels to disappear, become compressed, or merge incorrectly.
You can increase the resolution, but the width and height should always be scaled proportionally.
Recommended resolution steps:
1× Base Resolution 1672 × 944
2× Resolution 3344 × 1888
3× Resolution 5016 × 2832
4× Resolution 6688 × 3776
Higher resolutions require significantly more VRAM and generation time.
For the first test, I strongly recommend using exactly 1672 × 944 pixels.
You can increase the megapixel setting afterward, provided the same proportions are preserved.
Generating below the base resolution is not recommended because every individual portrait panel receives less image information, which may reduce facial quality and layout stability
