Have NullEngine example this effect to see ?

This is a pixel rendering similar to the UE. Is the cloud rendering scheme ?
I want a example look at it .

The null engine doesn’t render, if that’s your question.
You can use the webgl engine and an emulated canvas if you want to actually render your scene.
