Рендер камеры с заменой шейдера.
Смотри Rendering with Replaced Shaders страницу для подробностей.
Это будет рендерить камеру. Функция будет использовать флаги очистки камеры, целевую текстуру и все другие параметры.
The camera will not send OnPreCull, OnPreRender or
OnPostRender to attached scripts. Image filters will not be rendered either.
This is used for special effects, e.g. rendering screenspace normal buffer of the whole Scene,
heat vision and so on. To make use of this feature, usually you create a camera and disable it.
Then call RenderWithShader on it.
You are not able to call the Render function from a camera that is currently rendering. If you wish to
do this create a copy of the camera, and make it match the original one using CopyFrom.
