Check out this real-time Niagara sim! It uses Position-Based Dynamics, static volume textures to recreate the character's mesh, dynamically evaluated constraints and simulation stages. HQ: vimeo.com/425280683 #UE4Niagara #RealTimeVFX #UnrealEngine #Techart #VFX

Check out this behind the scenes look at some of the techniques that were used to bring The Matrix Awakens to life :) youtu.be/alQEf454PjU?t=956 #UE5 #GameDev #VFX #techart #UnrealEngine #realtimevfx

Unreal Engine 4.26 has just been released and along with it comes a ton of new effect examples. Crack open the "Content Examples" project's "Advanced_Niagara" hallway to give them a spin :)

I'm excited to share our first #UE5 demo. The tools that were written to support advanced flocking sims and insect swarms will be included in future Niagara releases. #ue4niagara #gamedev #realtimeVFX youtube.com/watch?v=qC5KtatM…

Distance fields are used in this test to transition points between a coarse grid and a regularly sampled isosurface. #UE4Niagara

This video may provide a little insight into how Fortnite's clouds are generated. A Zbrush-generated cloud texture is deformed via a rotate-about-axis derived distortion field. The sampled normals are equally rotated to compensate for the displacement.

Fortnite contains quite a few weapons :|. Manually capturing screenshots for each would be daunting. Luckily, this blueprint is able to cycle through each weapon in the game, frame the shots and capture high-res images for you :). #gamedevelopment #techart

We made a cinematic during Fortnite's first few months of development. During that time this automated rigging system was written. Simulate a soft body simulation in 3DS Max, run the script and convert the motion of key verts into bone-driven auto-rigged in-game anims #techart

Local space decal and gradient projection system's are useful when working with movable objects. This blutility converted a volume's transform into the mesh's local space before feeding it to the shader. Which allows the material to generate an internally projected decal.

This updated hologram effect was created with UE4's Niagara. A higher quality video can be found here: vimeo.com/295854817 #UE4Niagara #techart #gamedev #UE4 #UnrealEngine

This demo show's how up-to-date mass calculations can affect inertia. New Niagara modules can estimate a particle's mass using the particle's dimensions and an average material density. Rock, metal, wood, water and other presets are included. #UE4Niagara #TechArt #UE4

Support for static mesh morph targets has been added to Niagara. This allows artists to easily handcraft 3D particle distributions, attach particles to animated meshes and more. #UE4Niagara #techart #UnrealEngine

Scene capture actors render the scene's depth, color and normal information which is then used to reconstruct the environment within a Niagara particle system. Kinetic and potential particle energy is visualized as emissive light. The visuals will be tweaked. #UE4Niagra #techart

This Niagara demo can be examined in UE4's content examples project. #UE4Niagara #gamedev #techart

We're able to blend distinct and complex particle behaviors together by transferring particles between separate emitters. In this experiment, a particle spawns in an emitter, ages, dies and sends it's payload and a spawn event to a subsequent emitter. #UE4Niagara #techart

This rope simulation experiment was generated with UE4's Niagara. #UE4Niagara #techart #UnrealEngine #gamedev

This flocking system was written using UE4's Niagara particle editor. #ue4Niagara #gamedev #techart #UnrealEngine
