=== VRCMARKER PRO === A VRChat Worlds prefab for drawing 3D lines --- Try it out in VRChat --- https://vrchat.com/home/world/wrld_bd718520-e6ab-434b-a070-ee35b42f0d5f --- Features --- - In-game customization (adjust colors, width, smoothing) - Rounded line renderer for PC and Android - Late join sync - Per line segment eraser and undo - Subvidision on PC (Catmull Rom) - Gradients and solid colors - Time and pulled string smoothing - Write on surface mode - Desktop Hotkeys - No vertex limit - Json export --- Usage --- - Create or open a VRChat world project with VRChat Creator Companion - Download and import the Unity package. The imported assets end up in the Packages folder (Not assets) - Import TMP essentials if you havent already "Window > TextMeshPro > Import TMP Essential Resources" - Drag the marker prefab into your scene and adjust settings * Drawing On Surfaces * - Set "Collision Layers" on the marker to a new special layer - Create a GameObject with a primitive collider (Sphere, Box, Capsule or Convex Mesh Collider) set to that layer and enable "Is Trigger" - When a Marker enters a collider, it sets it as a target and draws at the closest point on its surface - Once the Marker moves outside the range, it continues drawing normally - Refer to the included example scene for the setup --- Changelog --- * [4.0.1] - 2026-1-11 * - Improved collision detection and setup - Fixed null exceptions when markers game objects are disabled by default - Added width to exported json * [4.0.0] - 2025-12-25 * - Complete rewrite - In-game customization - More desktop hotkeys - Removed vertex count limits and overwriting - Colored tooltips with more information - The geometry subdivision shader is now 3 times faster - Improved anti-aliasing - Writing on screen now works with any FoV setting - Reduced vram usage, the position texture is now dynamically resized like a list instead of a fixed constant size - Reduced mesh memory by using 16bit indices and multiple submeshes instead of one 32bit submesh for the line renderer - Holding erase now shows duration progress - Added distance culling - Fog can now affect the line renderer - Late join sync is now on by default - Export drawings in json --- Techical Details --- This prefab doesn’t use the unity line renderer component. It is a custom line renderer built with Udon and Shaders. This allows for more flexibility so things like dynamic subdivision and per segment erasing is possible. The eraser can erase any point and intersection tests are done on the GPU. All of the data is stored in a texture, once it is erased it leaves empty unused space. A defragmentation pass is also implemented in order to compact the texture. Remote smoothing is entierly shader based, using precalculated timestamps when line segments should appear. * Json Format * - "version" Version number - "createdAt" ISO 8601 in UTC - "boundsMin", "boundsMax" Axis-aligned bounding box - "width" Line renderer width - "colorType" Color (0) or Gradient (1) - "color" Vector3 color value - "gradient" Vector4 array with XYZ for color and W for gradient time - "positions" Vector3 array bytes encoded as Base64 string, line breaks marked with (0,0,0) * Example * --- JSON --- { "version": "4.0.0", "createdAt": "2025-12-25T14:42:54.5482376Z", "boundsMin": [2.560598,0.6142347,5.235921], "boundsMax": [2.764225,0.8806038,5.483546], "colorType": 0, "color": [1,1,1], "positions": "AAAAAAAAAAAAAAAAuFAqQKfVRz/XJaxAP1kqQNoMRT+VI6xA4W4qQJt3Pj+tL6xATX8qQNO/OT9LQ6xANX8qQCSHOT/oOaxAhG8qQH0SPT8eA6xAzWMqQH0gPz8lxKtAdWMqQMniPT+ikatAJmgqQAmAOz9zcKtA+G0qQEgNOT90WqtA1G8qQO5GOD+xU6tAAAAAAAAAAAAAAAAASlMqQHhwPj+r5apAtVUqQNFlPT+f26pAWloqQCmyOz9/06pAeV4qQD87Oj/1zapAnmEqQM0LOT8wx6pA8WUqQHGHNz8jwqpA5WcqQBfYNj/ev6pAAAAAAAAAAAAAAAAAPEcqQPjmQj99/KpA" } --- Contact --- Discord (https://discord.gg/bw46tKgRFT) --- Terms of use --- * Personal * Under the **Personal License**, you are permitted to: - Create modifications of the asset. - Upload the asset and its modifications to both personal public and private worlds.
