About this asset

UV Mask Painter

Paint crisp UV masks in the Scene view. Includes an Editor Tool with Paint/Erase/Smooth/Fill, per-channel R/G/B/A, and one-click PNG export. Create Mask Assets in seconds (R/RG/RGBA, linear/sRGB toggle, default values) and paint on any mesh with a MeshCollider. Editor-only; perfect for material blending, decals, wetness/snow/damage, and more.Key features
In-scene painting: Start/Stop from the Mask Painter window.
Brush: Radius/Strength/Hardness; Ctrl+Wheel radius, Shift+Wheel strength; Q/E size; 1–4 = tools.
Channels: Target R/G/B/A; Clear/Invert per channel.
Mask assets: Set size/channels/linear-sRGB/defaults; auto formats R8 / RG16 / RGBA32.
Live preview: Occlusion-aware rings; shows radius/strength/hardness.
Performance: CPU dirty-region uploads (~30 Hz).
Export: From the window or MaskAsset inspector to PNG.Typical uses
Material blending (snow/wetness/dirt), decals/wear, detail/reveal/height/edge effects—assign the resulting Texture2D to any shader in Built-in/URP/HDRP.Workflow (3 steps)
Add MeshCollider + MaskPaintable to the target mesh.
Create Mask Asset, pick size/channels/defaults, assign on MaskPaintable.
Open Mask Painter Window, choose Tool/Channel/Brush, Start Painting; export PNG anytime.What’s included

Technical details

Editor-only workflow

MaskAsset (ScriptableObject): stores resolution, channel layout (R, RG, RGBA), linear/sRGB flag, default channel values, and the generated Texture2D sub-asset. Includes helper to keep the texture persisted.

Texture formats & import

Formats auto-select by channel count: R → R8, RG → RG16, RGBA → RGBA32.

Painting tool (Scene view)

Tools: Paint, Erase, Smooth, Fill; select via the window or 1–4 keys. Q/E adjusts size; Ctrl+Wheel radius; Shift+Wheel strength.

World-space brush with UV-aware footprint. The tool computes a local surface frame (dP/du, dP/dv) per hit triangle to map world radius to tight UV bounds

CPU painting writes to a cached Color32 buffer; dirty rectangles are uploaded to the texture at ~30 Hz.

Pipeline compatibility

Editor-side authoring that outputs a standard Texture2D; assign the mask to any shader/material graph in Built-in/URP/HDRP as needed. (No render-pipeline code in the tool; usage is material-side.)

Compatibility

Unity version Built-in URP HDRP Custom
6000.0.35f1

Works with all pipelines.
