Each row represents ONE complete asset (vehicle, building, etc.):
ColumnView
1Isometric facing North West
2Isometric facing North East
3Isometric facing South East
4Isometric facing South West
5Special view (varies by asset type)
每一行代表一个完整的资产（载具、建筑等）：
列数视角
1朝向西北的等距视角
2朝向东北的等距视角
3朝向东南的等距视角
4朝向西南的等距视角
5特殊视角（随资产类型变化）

Row Organization

行组织规则

Organize rows by category/size:
  • Vehicles: Small to large, or by type (sedans, SUVs, trucks)
  • Airplanes: Commercial (rows 1-3), private (rows 4-6)
  • Buildings: Similar style/era per row
  • Nature: Trees grouped by season or type
按类别/尺寸组织行：
  • 车辆：从小到大，或按类型（轿车、SUV、卡车）
  • 飞机：商用（1-3行）、私人（4-6行）
  • 建筑：每行保持风格/年代相似
  • 自然元素：树木按季节或类型分组

After Generation

生成后操作

Once the asset sheet is generated:
  1. Save to 
    /public/assets/
    with descriptive name
  2. Follow the adding-asset-sheets guide to integrate
  3. Configure in 
    renderConfig.ts
    with correct row/column mappings
资产表生成后：
  1. 以描述性名称保存到 
    /public/assets/
    目录
  2. 遵循添加资产表指南完成集成
  3. 在 
    renderConfig.ts
    中配置正确的行/列映射

Common Issues

常见问题

ProblemSolution
Inconsistent sizingSpecify "same size for all assets"
Shadows appearingExplicitly state "NO SHADOWS"
Wrong projectionsReference compass directions (NW, NE, SE, SW)
Cut-off assetsAdd "centered in each cell" to prompt
问题解决方案
尺寸不一致明确指定"所有资产尺寸相同"
出现阴影明确声明"NO SHADOWS"
投影错误参考罗盘方向（NW、NE、SE、SW）
资产被裁剪在提示词中添加"每个单元格内居中"
