Blender's most epic tornado yet, by Alexander Weide
Hej Blender Community.Blender Cycles and Smoke Rendering with Cycles is awesome. I want to share this big test project with you all.
Hope you like it.
The biggest challenge was not the smoke, it was the soft-body deformations of the trees.
I used a lattice box for every tree so that the vortex force could deform them. Most of the trees are particle hair instances. i need 600 of them, so 600 lattice boxes was not a option i tried it. But this doesn't work. So I made a mix between a couple of lattice boxes and different versions of the trees. to scatter them around with particles...
The Nuke compositing consists of more than 30 layers. 7 (GB of RAM in use every time) in Nuke I retimed the simulation from 220 frames to 291 frames to get a smoother movement of the clouds and the smoke.
some facts:
- project duration: 7 Days
- project size: 69 GB
- 5 Smoke simulations 1 Soft-body Simulation for the trees.
- Rendertime on 720x1280 about 3 Days for all layers, this includes all tests.
- Simulation time of all around 12 Hours. ( Smoke Simulation in Blender with a grid box of 200 and a smoke wavelet subdivision of 4.

Totally jaw dropping!

Wow! That tornado FEELS mighty! Great work, Alexander.
BIG Thanks to all of you, never thought that this animation has such an impact;)
Great Job !!! I just have a little question, How do you get the normal for the smoke ?
You cant get the normal. That is rgb lighting. You need three suns. One for red one for blue and one for green.. that is the normal workflow.
Why nuke?
because of Retime, and because of the grid wrap deformer the faster compositing. The tornado sequence shot got 20 sec for calculation and more than 100 nodes for roto masks and tweeking stuff
Okay, I don't know much about Nuke, I just know it's expensive. :P
yes but if you work professionel its a must have and every penny invested in nuke is well invested.
most studios around the world using it. because its the best
