Working on the guts of the Visibyl particle system! Here's a demo of the most recent change: modulate _any_ of the system parameters with either an audio signal or an LFO-style modulator... Music: EASE UP by the amazing EPROM youtu.be/isF8WrKfwS4

Been a while since I posted but I got custom volumetric shadows working with our particle system today and I'm pretty pleased with the results (posting the YouTube version because particles and Bluesky compression aren't friends...): www.youtube.com/watch?v=qgCW...

Hey #GameDev, do me a favor and boost this skeet from @bmann.ca! It'd be great to get the games industry involved in this early verification process. 🥰

What’s a game that is universally loved that just didn’t click with you? Spelunky 2. On paper, it's my perfect game. I've over 600 hours in Noita and I LOVE roguelikes. I just couldn't get into it - really tried, too. Over the years I put in, like, 30-50 hours but it just never clicked for me.

Back to the particles today! Got the system all hooked up to real-time audio input for "ListenState" which now outputs audio spectrum info! I've found that the state machine is really helping to manage complexity now.

One of the cool things about shifting my particle simulation wholly to compute is that I can decide *exactly* which kernels to dispatch. This means: particle state machine!

Sadly, I’ve had to head back to my family home to look after my mum who’s going in for surgery tomorrow. She’s okay, but will need help during her recovery. It’s meant that I’ve not been able to concentrate on my work as much as I’d like, but some things are just more important!

The "bluesky is an echo chamber" think pieces that keep popping up really tickle me because they show how certain people genuinely believe social media should be for debating and arguing and not talking about the things that make you happy and sharing art with the world.

Been looking at the Slang shader language/Khronos announcement and it seems really interesting! Although the fact that it's Unicode rather than just ASCII makes me worry that if it's ever used in Shadertoy we'll have to decode `float3 💩 = 🐽` as well as the time honoured `a = b * p`...

Hey #unity devs! What do you prefer to do for player movement in a top down 2D game where physics isn’t important? I’ve settled on updating a rigidBody’s linearVelocity to get collisions from the physics engine but nothing else. Curious as to what others did!

Back to playing with swarm simulations for an as yet undisclosed game project. Trying to model the idea of a devouring swarm of Von Neumann cubes... This time I decided to move away from flocking (boids) and try playing with curl noise. I think the motion here "feels better"! #madewithunity #vfx

Making progress on an idea to try and create a "living liquid" effect. Decided to play around with Unity's HDRP post process volumes to see how far you can push screen space techniques to fake fluids. Custom compute for the particles themselves, still. #technicalart #madewithUnity
