Ognjen Ilkic : Sketch#55

Hey all :slight_smile:

This will be my first ever entry in any sketch so far, so I’m really excited :smiley:

Lately I’ve been experimenting with Grid2D and fluid sims in UE, so I guess this is a good opportunity to push myself and hopefully make it in time.

My idea is to recreate the Hiss effects from Control.
Since it’s a very complex system which is an artistic pillar of the game, my guess is they spent quite a bit more than a month to make it :smiley:
So I will try my best to make it look as authentic and perform in a similar way on the tech side as much as I can, but certainly not going to be the actual thing guys at Remedy did for this effect.

Even if I don’t make it in time, it will still be a nice excuse to spend some time to learn new things :slight_smile:

My ultimate goal is to make a working sequence which uses the levitating debris attack on some NPC, explosion + Hiss fluid sim like in this clip:

Wish me luck :slight_smile:


Still in a experimental phase, trying out different stuff. I’m still focusing on the fluid sim part.

At first I was trying to do it all with just particle position reading, but that wasn’t going to get me far. So I opted to use the gBuffer layers for sourcing. Still a lot of work to do, but it’s a start.

In this example I’m using custom depth to mask out what I need for sourcing the simulation, so the mesh and particles work without any separation. There is also some basic noise advection, chromatic aberation and desaturation filters.

Next on the list is to investigate how to use the velocity buffer to further advect the sim and a lot more tinkering :slight_smile:


This is looking fantastic already! Nice work :smiley:
