Tristan Reimus: Embergen Challenge


Will update this front post with GIFs of my latest work

Excited to join in a challenge again, going to be a good one! Can’t wait until the topic is revealed


The topic is great! Immediately had to think of this amazing video you might have seen on reddit (subscribe to r/schockwaveporn :slight_smile:)

I’m going to spend my session today trying to recreate the timing of the shockwave and the scale of the scene. Not sure yet if I want to go more stylized or fantastical with it later, could be cool!

Here’s the scene that I put together, the ground is using quixel textures and doing lighting with the new UE4 sky atmosphere.

For the explosion in the background I started with the ‘mini-nuke’ preset and used the fuel loss and flame extiction params to keep the flames alive a bit longer, also added some wind and changed the post to blur becauce its far away anyways so all detail of the sharpen is lost.

You’ll see the explosion anim reach its end because the flipbook+motionvectors mat function doesn’t support different frame counts per axis so I had to drop half of em, I’ll fix that :slight_smile:

The shockwave was a quick job but planning to use some smooth embergen generated textures and added smoke particles. Also thinking about adding secondary explosions after the initial blast, could be closer by so they blow out the camera.

That’s an epic explosion. Good work.

Working on the secondary shockwave now, added some debris and simple a simple smoke texture.


Going to have another session tonight, might get too late to post again but we’ll see. Tempted to go a bit crazy with it and add some cracking earth and maybe even fire colomns shooting out of the ground?
