a screen-space shading technique that defers shading until the second pass of rendering

In the field of 3D computer graphics, deferred shading is a screen-space shading technique. It is called deferred because no shading is actually performed in the first pass of the vertex and pixel shaders: instead shading is "deferred" until a second pass.

It is used in numerous popular games starting around 2010.

Advantages: easier resource and pipeline management

Disadvantages: hard to handle transparency, multiple materials, incompatible with anti-aliasing

Setting a SCNTechnique stops SCNSceneRendererDelegate

When I set a SCNTechnique to my SCNView, my SCNSceneRendererDelegate stops to work. Are there any workarounds? I want to execute some code before and after scene rendering. I've tried to reset the delegate, but It doesn't help. Thank you!
