VFX Graph: Six-way lighting workflow | Unity at GDC 2023

Want to create great-looking smoke effects? In Unity 2022.2, VFX Graph introduced the six-way lighting output and DCC tools that you can use to create compatible textures so you can create volumetric-looking smoke under any lighting conditions. In this hands-on session, a VFX Graph senior technical artist walks you through the process of creating six-way lighting textures and using them in VFX Graph.

oooh can wait for the particle shadowing, that's looks cool

Unity needs to see a presentation about the use of noise impression.

[jeffkuipers]

Very nice presentation. It's a very in-depth exploration for the limited time you had available. Well done!

Would be good to show how to export flipbooks from blender or embergen to unity

I love this and think it's awesome, and I'm getting some nice-looking results from a quick smoke simulation in Houdini rendered out ... but the problem is, there's NO explanation anywhere (at least that I have been able to find) that explains how Houdini tech artists should render/process their work and how that maps to Unity shaders and features ... I used Lab Flipbooks, but it seems to be designed for Unreal and nothing else ... lots of places where Unity and VFX Graph and special tools are mentioned, zero explanations and no way to find it and be sure it's the right thing (much less how it's intended to be used) ...

This issue also isn't limited to just this scenario: I find Unity + Houdini resources sorely lacking across the board ... and I keep having to just invent new tools and workflows to get from Houdini to Unity ... and I guess it's just gonna require a bit of extra production time & effort to tool ourselves up properly to take advantage of our full potential. I wish it weren't like this and that Unity and Houdini were a bit more seamless with more clear paths and workflows, but unfortunately, it's like you're on your own exploring strange frontiers lol. But I'm so enthusiastic and excited about the idea of proper Houdini -> Unity integration I would literally take a job for either company to work on this, haha 🤓

I wonder if they have a demo scene of VFX six way

[noisecrime]

Good presentation, but the extensive dimming outside of the focused area was really distracting, especially when quickly moving between UI items, causing the whole screen to constantly dim and brighten. It also made it much harder than necessary to read elements that were on screen.

Hi. The VFX Graph DCC Exporter fore Blender don't seem to work. Is there a guide on how to install it ?

[SylkieDev]

Why are there so many people talking in the background...

[Lexart]

Still, no way to use it with ray traced GI :(

[impheris]

looks cool i guess, tg there is a free pack that i can use because i'm not going to spend more time on that complicated (in my opinion) workflow

[mikeb]

Wouldn't voxel smoke be better than flipbooks now?

[GameRocker]

Why is every Unity GDC talk produced so badly? Such a massive company needs to be good at these things.
