Just released and very nice!
Everything done in UE4, except sand and dust VFX done in Houdini.

Last shot shows mad-maxesque sand storm, in slow motion.

Is that achieved using motion vectors [www.sidefx.com]?
My understanding was that with motion vectors you end up with an animated texture material which you apply to a 2d pane, but in the shot the camera is moving in the 3d space and seems not to reveal the (possible) two-dimensional quality of the sandstorm…

Or maybe, to reach the 3d appearance, they just populated a big cascade particle system with lots of motion vector textures as particles, like you would normally do with normal flipbook textures? Can you even do this?




cheers

I thought a lot of their stuff was pre-rendered. If that dust storm is realtime then it looks like a variety of smoke plume sims rendered as subUV textures and the placed in layers. It doesn't look slow motion to me. So that probably isn't any need for motion vectors.

ah yes, that makes sense!
