Make your first Niagara Fluids simulation in Unreal 5.7. Full process beginner tutorial for this desert monster is included in my Free Witcher VFX Course: RedefineFX.com/witcher

New Unreal 5.6 River tools used in The Witcher 4 demo make it easy to add water simulation to a landscape - it realistically collides, generates whitewater, and even supports buoyancy for floating objects. All in real-time. Tutorials have been added to the Unreal Megabundle.

@RedefineFX Amazing!

@WC_Vanyster Good feedback- thanks!

@dmpvfx Excellent presentation. I have 3 notes on the raft demo: 1 - at 2 places the white water foam seemed obviously far too constant and made the water feel fake. 2) please see if you can apply material wetness to the surrounding landscape and objects. 3) at the end there were lines

Come check out my #UnrealFest talk on simulating rivers! It is at 3:30pm today in South 4. We'll talk about using it in the #Witcher4 demo and also a small whitewater rafting game we built. Livestream of the talk here: youtube.com/live/0X6amtHcr….

I just opened enrollment in both Niagara Fluids Immersion & Chaos Destruction. Very beginner-friendly courses and a great way to start learning real-time VFX in Unreal. Enrollment closes again in 5 days redefinefx.com/epic/

Some of the best #Niagara Fluids work yet!

Real-time carpet bombing simulation with Niagara Fluids in UE - very fun to move the emitter around and watch as the carnage follows 🤩 Learn how to set this up inside Chaos Destruction. Final call: enrollment is closing in a few hours (link below)⬇️

Awesome real-time simulations from Sam Gielen, student inside Niagara Fluids Immersion.

youtube.com/watch?v=Z_Dssj… My Heterogeneous Volumes system was featured in yesterday's State of Unreal. It was a lot of fun working with Skydance New Media to push the limits of what we could achieve. Everything demonstrated here will be in the upcoming 5.4 engine release.

@jukerlaw Data channels are a way for Niagara Systems to communicate their particles between each other. It only works wirh CPU particles right now, but is a nice way to have multiple Niagara System actors for source particles feed into a fluid system as a source. Lots of other uses too!

Next up for our tour of #UnrealEngine5.3 features - data channel emission! This lets you source fluid from particles that are part of a different system. This is very handy for working in the viewport as you can easily modify your sources without opening the #Niagara Editor.

Playing with these real-time smoke sims for the whole day, Niagara Fluids system in #UnrealEngine is mesmerizing.

Some great work to make #Niagara Fluids 3D liquids rendering look way better!

@danielelliott3d @jose_morval @UnrealEngine There is a lot of magic under the hood, but Grid2D will let you read from the previous grid values stored in the previous buffer, then write to the grid values in the current buffer. This lets you do various grid bases update operations with double buffering behind the scenes.

@jose_morval @UnrealEngine you can probably do it, but there will probably be a race condition. I know that grids take care of a source and target for each stage that gets swapped but I'm not sure render targets do that. @dmpvfx would know :)

Hey @UnrealEngine (and Niagara folks) . It's been time since I use a Render Target 2D as Data Interface in a Niagara Simulation Stage. Is it possible to write and read from the same render? #gamedev #indiedev #unreal #niagara

Real-time explosion simulation made with Chaos & Niagara Fluids in Unreal Engine 5.3 Today I'm opening the waitlist for Chaos Destruction, where you will learn how to destroy anything in UE5, join the waitlist for the upcoming RedefineFX course at the link below⬇️

This is a very cool workflow!

@GhislainGir We have a 2d FFT based pressure solver in 5.4! Similar performance but fully convergent.

Last time I checked, UE's Niagara fluid examples still all used the standard navier-stokes approach, right? Has this poisson filters method been implemented in UE yet? I'm not up to date, too many things happening everywhere all at once 😅

#gamedev #fluid #vfx #Ubisoft Reminder that this exists: youtube.com/watch?v=_3eyPU…

Hard landing. Real-time destruction sim made with Chaos & Niagara Fluids #UE5

You can find it here in your 3D gas emitter

#Niagara Fluids has a checkbox for deterministic particle sourcing, which gives you the exact same results each time you run a 3D gas sim without changing it. It's useful for your #UnrealEngine5.3 cinematic shots!
