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...

BLUESKY GIVEAWAY: - 1 Bigscreen Beyond 2e: @vrchat.com Edition (no 10 years of VRC+, sorry). As long as Bigscreen can ship to you, you're eligible. RULES: - must be following me on Bluesky - must RT this post you must be comfortable with me ordering it for you!

I made a Light Volumes debugging tool that can be integrated into avatars!

Anyways, here you can see the "Femboy Advanced" Camera in action I'm glad I managed to emulate the crappy Framerate in the shader too :D (Probably still a bit too high)

VRC Light Volumes! They look amazing! Go find out more:- github.com/REDSIM/VRCLi...

アバターやワールド向けのGame Boy Advance風プロップ！パララックスで内部を表現し、光をぼかし・屈折、VRCLV＆Unityライティング対応、FPSグラフ表示やGIF再生も可能！Boothで公開中: redsim.booth.pm/items/7272387

MY GAME IS HERE!!! I wrote and drew a free wlw visual novel for #WomensGameFest! You can romance either a game developer or an aspiring artist (OR BOTH!!!!!) Download it here and let me know what you think! flarechess.itch.io/flour-girls #gamedev #indiedev #visualnovel

Point Light Volumes with animated cubemap projections! Can't wait to see pool worlds using this. By the way, you can bake 3D shadow masks to cull the projections in places where they shouldn't be!

I hope this makes it onto the VCC Curated packages list soon given it encourages people to optimise their worlds and use baked lighting which is a big issue in some worlds

yes it would be a good idea to update your avatar shaders to latest builds

Light Volumes v.2.0.0 released! Now it has Light Volume based super optimized analytical Point Lights, Spot Lights and Area Lights. (Up to 128 at the same time) Ability to project images and cubemaps. Also baked shadow masks and even more features! github.com/REDSIM/VRCLi...

Just reworked the light sources attenuation in VRC Light Volumes 2.0 You'll be able to set the size of a light source itself, like a bulb's radius, instead of setting the range of the light. It's completely different comparing to Unity's lights, but the overall visual look is more physically correct

Light Volumes 2.0 will support baked 3D shadows for point and spot lights, and that's how it can be used! Thanks to @pema99.bsky.social for implementing this feature!

WOW...this 2.0 update for LightVolumes + the Baked Volumetric Edit is HUGE for stage lighting! There are no projection meshes, nor volumetric meshes, just light volumes and fog. @sim.red you are a wizard🧙 @ikeiwa.dev you too are amazing for the continued support with the updates to the fog!

Apple Liquid Glass VRC Light Volumes support coming soon...

Area Light Volumes... Thanks to @pema99.bsky.social for implementing and contributing such an amazing feature to VRC Light Volumes! I can already imagine people using it as studio softboxes for photography!

Technologies change, the problems stay the same. Was trying to improve the results with @sim.red Light Volumes Original clip by @crowscrowscrows.com #unity3d

Now Point Light Volumes supports Cubemap projections! Volumetric fog makes it look just stunning! But here's some bad news... If I release it, all world creators will need to update their worlds to the new Light Volumes version. Otherwise it will break the back compatibility.

Point Light Volumes prototype! They can be both Point and Spot Lights, can be calculated mathematically or use a special LUT texture that controls the cone falloff and attenuation! Up to 128 lights per scene. Works up to 3- 4 time faster than regular Light Volumes. AudioLink works too!

Spot Light Volumes! Everything is parametric here and not baked into a 3D texture, as regular light volumes, which makes it even more optimized. Will work on it a little bit more and see if it's worth to add it to the main project branch.

Point Light Volumes? Not sure if I will integrate it, but I just don't like people using baked volumes as fake point lights and spot lights. Integration for shader makers would just require to update my .cginc file I provide. For people - to update the shader and reupload their avatars again.

VRC Light Volumes v.1.0.0 released! A VRChat asset that brings nextgen voxel based lighting into your worlds! Get it here for free on my GitHub: github.com/REDSIM/VRCLi...

VRC Light Volumes AudioLink support! Just imagine VRChat clubs using this! Minimal performance cost and buttery-smooth FPS, even on potato PCs. Thanks to @vard.cc for integrating AudioLink support

Okay, so that's a Bigscreen Beyond face tracker I assembled today. Can't even say that it looks bad. Works nice too.

I just implemented dynamic additive Light Volumes feature! It can be used as super optimized real-time lights. No shadow casting but still looks cool. Here I also integrated it into Silent's Filamented shader to make it work with lightmaps on baked objects too.

This week I've been working on the VRChat Light Volumes scripts to bring you an easy and comfortable editor workflow. I also implemented the Volumes rotation feature and optimized the shader a lot to make it work even more solid on potatoe-PCs. Here's a small video of how it currently works.

VRC Light Volumes is a next-gen voxel based baked volumetric lighting solution for VRChat, I'm working on right now! It affects avatars, dynamic props, etc. Works really fast without major overhead even on Quest. It will be fully open-source and free, so stay tuned! #vrchat #gamedev #shader
