@elbethium Thank you for stopping for a moment of appreciation. I put a lot of care and love for this effect.

I'm happy to quote this :). There's a great opportunity to come join us to explore what can be done with VFX tech in the context of games.

I'm looking for TA to join our VFX team. If you have worked with shader code before and are interested in developing new realtime VFX tech, I encourage you to apply. Feel free to DM me if interested.

@amu_mhr @JankkilaRisto Cool stuff! Probably worth trying a dim of 32x32x64 since the character is upright. Should fall somewhere in the middle of your perf figures
English
@JankkilaRisto 64x64x64 R16F: 0.12ms
32x32x32 R16F: 0.03ms
for 23 capsules
For collision you don't need SDF texture, particles can directly query closest distance
It's not super cheap ^^'
There's no acceleration structure, just iterates over all the capsules/spheres/boxes in the physics asset

@amu_mhr The data is stored in a 3D texture. The bounding volume is in R32_Uint format. Each voxel represents a 4x4x2 volume.

@SharmanJag Are you doing anything clever (or is it even possible) for storing the bit fields? or just using ints... :?
Wondering if particles hammering atomics on packed bitfield could degrade performance. I have not tried any of this so not sure :p
Very clever setup!

Breaking down effects with @JankkilaRisto. In Returnal we used a piece of tech that we call, Occupancy Volume Physics for making the death effect of the Gorgolith. I just made that term up but the following effect is real and it's how it can be seen in the game 1/n.

8/ Conclusion: I think the effect works well even if the physics in it is far from realistic. What do you think?

7/ The effect consisted of three phases. 1. Rock formation. 2. Front-To-Back Sweep where the rocks detach. 3. Rocks Dissipating. Here's how:

Here's a final version of the alien grass effect from Returnal that wakes up and grows when Selene approaches it.
Let's have a look at some work in progress versions of this effect along with explanations on the creative choices that were done during it's development. 1/n

In Returnal, Xeno-archives are visual depictions of important events in the games' lore. They were done entirely with our proprietary particle engine. Here's a video of the first version of the effect that we did

I'm very excited to announce that we are going to speak together with our Lead VFX artist @JankkilaRisto @ViewConference about how we used our proprietary VFX engine in #Returnal. I'm equally excited since this is my first ever tweet. Well, at least I did it before my kids

A great opportunity to learn how our #VFX team solved many question during the development of #Returnal by using particles 👩🚀✨

Our GDC talk is now on youtube. Thanks to everyone who came to see it and the q&a session afterwards!
