VRC Light Volumes v.3.0.0 is now ready for a public BETA test! It's a beta test that is mostly for creators: I want you to check if it works in your worlds an if you have problems integrating it in your shaders. (Enable Pre-Releases in your VCC to get it) github.com/REDSIM/VRCLi...

2.0 is here! Featuring experimental screen sharing, along with many fixes and stability improvements. Unfortunately, screen sharing is currently available only for self-hosted servers because it's too expensive for me to support it on the public one. I also...

This is incredibly useful! It's crazy that you made such a service for free.

Using @sim.red VRC LV 3.0 dev 2 with @pimaker.at LTCGI 1.7.1 for avatar lighting support, looks perfect. Also shout out to @frostyx.bsky.social for posting about the force scene lighting tech

I made physically correct speculars for VRC Light Volumes v.3.0.0. Now we'll have them separate per each light, so no specular-leaking artefacts anymore! Also now speculars use light source size to look much more physically correct.

I've finally released LTCGI 1.7.0, integrating @sim.red 's VRC Light Volumes! I have also decided to record video patchnotes: www.youtube.com/watch?v=ylRA.... I'm not @strasz.bsky.social , but it's fun to try. Download and docs on ltcgi.dev as usual.

VRC Light Volumes v.3.0.0 will support Area Light realtime texture emission, almost like LTCGI. Less physically accurate, but very performant!

I watched "The Amazing Digital Circus: The Last Act" today. No context, so it's not a spoiler, but I made something related on VRC Light Volumes v.3.0. I can already imagine how great it will fit VRC chill worlds...

Still working on VRC Light Volumes v.3.0 Here are some realtime shadows with volumetric fog... (Extremely expensive but cool)

I really love new VRC Light Volumes shadows! But I have to tell you that realtime feature is very expensive, more expensive than Unity's default shadows. So such shadows should mostly be used in baked-realtime mode, when players can only receive shadows, but not cast.

@sim.red refactored the LightVolumes.cginc and now the compile time increase is mostly gone compared to current v2.1.3

New prototype of VRC Light Volumes real-time shadows! It uses EVSM сontact-hardening soft shadows. Performance seems good on PC, but I will do more tests. Finally something that looks better than what you can achieve in Unity by default!

Realtime shadows in new VRC Light Volumes. Probably not what you actually want to have usually... But can be very useful if you want to rebake your shadows in runtime! It can be triggered just once and then you can go fully baked with no overhead.

Took a quick video of the minecraft block renderer of my pool. youtu.be/edDpyBy3zzo

Another thing that is going to be released with next version of VRC Light Volumes, is an in-game debugger tool! You'll be able to preview every volume, voxel, and point light. Works in any world that supports VRC Light Volumes.

I'm working on a new major VRC Light Volumes update! - Baked realtime shadows (very performant) - Animated cookies and cubemaps - Optimized area lights - No more legacy code - Almost full back compatibility with older light volumes shaders (excluding new shadows)

Do you remember the caps game from the 2000s? I thought it'd be cool to recreate it in VRChat as a game world where you can collect them. What rules did you use? (I know they varied by country)

Light Volumes v.3.0.0 release! - Realtime lighting, speculars and reflections support - Fully path-traced global illumination (Quest compatible) - Spherical gaussians support - Even more performant! Full feature list here on github: github.com/REDSIM/VRCLi...

Finally, finished my Divergence Meter casing! Will also need to make a proper firmware for it with ability to control it over Bluetooth/Wi-Fi

Working on something... NOT SOON (TM)

Just completed "Venture into the (Un)known" @vrchat.com event and discovered all the secret tapes!

I think I have enough improvement ideas to make VRC Light Volumes 3.0. But more features means more if's and for's, which increases shader compilation time dramatically. Would be really nice to have global keywords specifically for Light Volumes, which would solve this issue.

GPU Infinite Grass v.1.2.0 released! - Surface Normal support (better shading) - Correct light attenuation (was broken before) - Unity Fog support - Editor GUI improved - Other fixes Already available on Booth and Patreon: redsim.booth.pm/items/7997362 patreon.com/posts/150937...

A very rough proof of concept of Baked Directional AO for VRC Light Volumes. I'm not sure if I want to integrate it into light volumes for real, but it could be a VERY performant solution to make super cheap realtime contact shadows.

GPU Infinite Grass v.1.1.0 released! - Unity Terrain support - Surface Mask shader improved - New surface setup workflow - You can now draw grass on ceilings too - Fixed several bugs where grass wasn't rendering in VRChat or Play Mode redsim.booth.pm/items/7997362

Testing GPU Infinite Grass with Unity Terrain... And I surprised how perfectly liminal it looks with just a default terrain texture!

Working on the GPU Infinite Grass most requested feature: Unity Terrain support! Gonna be in the next update very soon, as well as lots of small bug fixes and improvements.

It's only one hour left to get GPU Infinite Grass with 20% discount! redsim.booth.pm/items/7997362

Today is the last day to get GPU Infinite Grass with 20% discount!

I accidentally made the GPU Infinite Grass Booth page private for an hour or few... X_X Sorry for that! Now it's available again: redsim.booth.pm/items/7997362

My new "GPU Infinite Grass" is finally out! Renders millions of grass blades to the horizon! Mobile/Quest-ready, Light Volumes support, bendable by players and objects. Available on Booth & Patreon. 20% off for the first 3 days! redsim.booth.pm/items/7997362 patreon.com/posts/150937...

I remember it like it was yesterday...

Hacking to the Gate

I finally made the Divergence Meter prototype work! Now need to polish it and write a proper firmware.

Mururururururururururururu!

Just got some PCBs I designed from JLCPCB. I hope, this thing will work as expected!

My grass system is now closer to the release! It's now possible to draw up to 3 types of grass, or even more, but randomized or sorted by size. You can draw it on top of any mesh with the brush instrument I provide, or with vertex color paint in Blender.

I was bored today, so I made an ESP32 pixel-camera. Would be really cool to make it a real portable device, but I'm too lazy (have a grass shader to finish)

Today I improved GPU Grass with a feature I call "batched instancing". It builds a grass batch at runtime and instances it. No world size increase, less GPU memory usage, runtime grass amount control, and better perf. 144 FPS with 11.2M grass triangles visible to the horizon!

Here's something I promised to show you… GPU grass that is actually fast and usable! It can be dynamically scattered over any mesh in your scene, can be bent by people's avatars or props, and it even works on Quest and mobile just fine. Still WIP, but you can check this world:

The PCB I was working on and ordered from JLCPCB. I hope it will work when I assemble it! I bet, some of you can easily guess what it's gonna be...

I can't stop working on new GPU particle systems. That's so many optimized stuff you can do with it! Will show you something really cool later...

Just pushed out a new v7.2.0-dev.1 pre-release of my shaders. Ever wanted some snow coverage in your worlds? Now its just a couple of clicks away! Docs: dev.shaders.orels.sh/docs/special... Grab it on VCC, or GitHub: github.com/orels1/orels... #shaders #unity3d #VRChat

Working on a PCB schematic for a device I wanted to make years ago...

Only two days left until 2026, and I'm releasing a new GPU Fireworks asset to celebrate the New Year! It includes timer that launches fireworks at each time zone. You can also generate any firework mesh you want! And it lights up the world with VRCLV. redsim.booth.pm

GPU Particle Volumes got a few hotfixes. Version v.1.0.3 is out! If you installed it via the .unitypackage, please re-download it from Booth/Patreon. VCC users can simply update the package. The snow shader itself hasn’t changed.

Today I release new GPU Particle Volumes system and the GPU Snow Particle shaders for it! This snow shader can render hundreds of thousands of particles at the same time even on a weak GPU. It also supports VRC Light Volumes. Get it on my Booth or Patreon! redsim.booth.pm/items/7733242

FlexiCurve, my garland tool, updated to v.1.2.1. Now it supports tinsel garlands and VRC Light Volumes! And it's open-source and free: github.com/REDSIM/Flexi... You can also support me buying the new tinsels preset for it on my Booth or Patreon! redsim.booth.pm/items/7676455

Experiment with porting @sim.red 's excellent VRC Light Volumes to #VNyan (and other general Unity contexts) This voxel-based light system by RED_SIM is unbelievably performant, allowing you to create complex lighting effects while going easy on your framerate. Coming soon™ to a plugin near you!

Light Volumes v.2.1.0 update is here! New features: - Light Volumes downscaling (useful for smaller builds for Quest) - Progress bar while baking 3D atlas (no more looks like nothing happens) - Audio Link script improved - More! github.com/REDSIM/VRCLi...
