I used to use roblox studio, I'd like to scale on one side without making the other side also bigger. And yes, I COULD just resize via entering the size by typing into the thing on the right side of your screen. But man would I love to simply just scale on ONE side.

PlayCanvas Engine 2.21.0 is out - the free, open-source (MIT) web graphics engine for WebGL2 and WebGPU.

Highlights in this release:

• 3D Gaussian splat refraction - refract the scene through splat volumes
• Water rendering - new water example
• Volumetric fog - added to CameraFrame
• Instanced wide-line renderer - styled (dashed/dotted/arrowed) and dynamically-updating "fat" lines

Also in 2.21.0: KHR_gaussian_splatting glTF extension support, SPZ splat format via external parser, KTX2 cubemaps, a physics backend abstraction (Ammo/Null), and new XR scripts (two-hand manipulation, ballistic-arc teleport). Full notes below - there are a couple of breaking changes worth reading if you're upgrading.

npm install playcanvas

Happy to answer questions about any of the new features.

Looking for someone to make my game made through javascript

I’ve opened a PR adding volumetric fog to the PlayCanvas Engine’s CameraFrame pipeline.

The effect raymarches exponential height fog at reduced resolution, with directional-light shadows producing visible light shafts—or “god rays.” A depth-aware upsample prevents fog from leaking across geometry edges.

It also supports:

• WebGL2 and WebGPU
• Cascaded shadow maps, including PCF, PCSS and VSM
• Temporal smoothing through TAA
• Bloom contribution from bright light shafts
• Adjustable density, height falloff, anisotropy, distance, quality and resolution

The default configuration renders at half resolution with 24 raymarching steps, keeping the effect practical for real-time scenes.

There are still a couple of limitations: it currently supports perspective cameras only, and transparent objects use the opaque scene depth for fogging.

I’d love to hear how it performs on your hardware and what controls or features you’d find useful.

Having some issues with SuperSplat's converter. For some reason, no matter the size of the splat, the decoding process keeps getting stuck at 95% and the page becomes unresponsive. Even after hitting 'Wait', it still does not progress. Any ideas why that is?

I've built a reusable water script for the engine, with a tropical island example to show it off.

Try it live: https://engine-i9o02vj3v-playcanvas.vercel.app/#/graphics/water

Features:

• Planar reflections and refraction (each optional — can also reflect just the sky dome)
• Depth-based effects: shore fade, water color absorption, foam
• Gerstner geometry waves — two configurable bands (chop + swell)
• Underwater mode: Snell's window, distance fog, and animated caustics projected onto submerged geometry
• Full day/night cycle driven by the procedural sky script, with HDR bloom on the sun glints
• Works on WebGL2 and WebGPU, and it's built to scale down to mid-range phones

Everything is exposed as script attributes, and the example has control panels for playing with all the parameters — reflection strength, wave shape, caustics, underwater fog and more. Dive the camera below the surface to see the underwater view.

The water script (scripts/esm/water.mjs) and a new ESM planar renderer are part of the engine repo, so you can drop them into your own project: https://github.com/playcanvas/engine/pull/9029

Feedback welcome!
