人物换装系统
人物换装系统下
人物换装对模型的还是有一定要求的,首先换装是要有多套模型的,通用做法是将人物的身体(包含头),衣服、裤子、鞋子、头发分别作为一个部位,然后将这几个部位动态合批成一个人物模型。有的人身体和头也是分开的部位这个看做模型那边的情况具体定。还有的不要身体直接分成衣服、裤子、双手、双脚、头(包含头发),我这里介绍的也是这种方法这样也能避免很多蒙皮问题。
之前我们在做换装人物合批的时候也遇到过几个影响比较大的问题这里我拿出来说一下。
针对蒙皮穿模的这种情况其实有很多办法
如下所示把其中一个赋值好材质的模型预制体拖上来,红框是每个需要合批的部位。
将上述拷贝的部位改名如下
全部拷贝出来如下所示,这样的对象是包含根节点信息的
改名如下
眉毛和脸模型都是一样的就不需要合批处理只用一个即可
这里我只是用了一个模型来讲,换装肯定有多个模型,其他模型也是这样处理,第一个模型名字我后缀都是1,后面的模型依次后缀是2、3、4…
创建文件如下,并且将上面的拷贝的对象分别放到对应文件夹下做预制体
上图中脸和眉毛只有一个是因为都是一样的只保留了一份
创建一个动画控制器并双击打开
将待机动画拖拽上来
将之前的所有模型根节点中的动画控制器换成刚才我们生成的动画控制器

随便创建一个场景然后在随便一个对象上面挂载UCharacterManager.cs脚本运行测试
这个方案是将所有的Mesh合并成一个Mesh,材质球是叠加的并没有合批材质
注意:如果要想将模型完全合批需要将所有图都设置可读可写,这里放到另一篇文章去讲,这里先不讲合批材质的方法
