Volumetric Lights trick

[Adi]

Hello,
I've tried and tried and tried but I really cant figure out how this is done. Would someone please be so kind and give me a short step-by-step tutorial?

best regards,
melvin

Hey melvin, try with my settings as attached.

Really interesting techique , but slow render times and very noisy. Does anyone have any advice on that ?

Here is my contribution; rendering time 4h (image is 3000pix large)

No wonder the teacher is pissed of as the students are a) staring through the window, b) browsing facebook, c) running across the classroom with their arms close to the body with the speed of light.

btw, is this done with the moving plane trick? I wonder how this competes against the volumetric fog.

In fact the teacher did not look comfortable !
Well I only use a box with a CoronaVolumeMat and it's so easy to render.
I will test the technic with the plane ASAP... thanks Maru ;)
