如何在Unity3d中的GameObject后面绘制GL占位符

Question

I have a question that I can't find in a documentation. I use GL premitives to draw grid. But I can't understand how to push it behind gameObjects. Now grid is drawing on main Camera in OnRenderObject, and as result I see grid in front of gameObjects. If I draw it in Update or LateUpdate the grid is visible only in Scene mode. So, please, tell me what options do I have?

Looking over the documentation ...

I see...

• OnPreRender - OnPreRender is called before a camera starts rendering the scene.
• OnWillRenderObject - OnWillRenderObject is called for each camera if the object is visible and not a UI element.

Both of these fire before anything renders. Whereas the method you're using now has this description:

OnRenderObject is called after camera has rendered the scene.
