最佳实践

角色设计

• 轮廓：设计鲜明的形状，确保缩小后仍易于辨认
• 配色方案：将主色限制在 3-5 种，以保持品牌风格统一
• 清晰易辨的特征：大而富有表现力的眼睛、清晰的面部特征
• 标志性元素：加入令人印象深刻的配饰或特征

Live2D 准备

• 线条简洁：线条清晰利落，不带草稿感
• 平涂色彩：尽量减少复杂渐变，便于绑定
• 元素分离：清楚区分头发、面部和服装
• 正面朝向：采用面向镜头的标准中性姿势

表情表

• 保持一致：整体采用相同的美术风格和比例
• 情绪范围：包含基本情绪，以及角色特有的表情
• 差异清晰：每种表情都应一眼可辨
• 网格布局：排列规整，便于查阅

配饰和道具

• 风格匹配：与主角色采用相同的美术风格
• 尺寸参考：以合适的尺寸展示物品
• 多个角度：如动画制作需要，可展示不同视图
• 透明背景：便于在直播软件中合成
