本地电脑如何做网站,学校的网站建设费如何入账,一个网站策划需要多少钱,佛山公共交易资源平台搜了下大概有这几种方法
通过模板缓存通过shader裁剪区域#xff1a;案例一#xff0c;案例二#xff0c;案例三#xff0c;三个案例都是类似的方法#xff0c;需要在c#传入数据到shader通过插件
某乎上的模板缓存方法link#xff0c;#xff08;没有登录看不到全文案例一案例二案例三三个案例都是类似的方法需要在c#传入数据到shader通过插件
某乎上的模板缓存方法link没有登录看不到全文实现估计和上面差不多
如果使用的是模板缓存的方法给Viewport的image一个材质mat使用mask.shader即可然后修改粒子的shader。 mask.shader如下
Shader UI/UIMask
