In particular, the stencil values can represent a surface that can be lightmapped or even if it can be lit or not. Stencil is not a property used in shader but an indication to Unity on programming the Draw state. It appears like different rooms are shown, depending from which side you look into the box, but in reality all the objects inside the boxes are placed "on top of each other" and the stencil buffer is only used to mask out the objects that should(n't) be drawn. Every value corresponds to a pixel on the screen. Bit #6 (value=64) indicates non-lightmapped objects. Then it renders opaque geometry at event #10. I think this is even faster than doing a full clear every frame. 此命令会更改渲染状态。. ut ys mt mb mw cy uu nb wk ct
