三、Pass塊中的指令1.Name "MYPASSNAME"為該Pass命名,用於在其他Shader中通過UsePass命令呼叫該Pass,即使使用小寫字母命名,Unity也會自動轉為大寫字母,所以UsePass命令中也需寫成大寫字母2.GrabPass { "TextureName"}抓取螢幕並生成紋理,TextureName為自定義紋理名稱. 假设场景中有100个Cube和100个Sphere,他们共享一个material,在渲染循环自动处理的情况下,一次upload 200个实例数据到GPU,用2个draw call分别绘制Cube和Sphere。. 第1个draw call中unity_BaseInstanceID为0,第二个draw call中unity_BaseInstanceID为100。. #pragma shader_feature A其实是 #pragma.

内置的 Unity 着色器支持将 32 位 RGBA 值编码和解码为 32 位浮点数的技术。这可以通过简单地将每个 channel 与它之前的 channel 的最高可能值相乘来完成。由于它存储在浮点数中,因此预计会出现一些精度损失。 着色器显然有一些我试图理解的优化。.
