如果有更简单的实现方法欢迎各位大佬留言。
补充:unity 动态修改prefab 同步fbx
有时候我们想prefab和fbx无缝切换怎么办,也就是在unity里调完效果后不满意,返回dcc如阿健修改模型,但是prefab上又挂载了东西,不想重拖怎么办?这时候prefab variant就又用途了
建立变体,把变体拖到场景里。
或者先拖fbx到场景,再选择变体放置。
然后修改好模型后,直接再在文件浏览器里替换同名prefab
貌似需要到prefab模式里再revert一下
这样就可以实现“动态”修改perfab了。没改变的话可以右键相关属性revert
嗯
以上为个人经验,希望能给大家一个参考,也希望大家多多支持。如有错误或未考虑完全的地方,望不吝赐教。
