Flat UV Mapper

Flat UV Mapper brings the rapid, CSG-style (e.g., Source Engine / Hammer Editor) texturing workflow directly into Blender's 3D Viewport. It is designed for level designers and hard-surface modelers who need to quickly apply, scale, align, and manipulate planar UV projections without ever opening the UV Editor.

Key Features:

• Projection Modes: Choose between World-Axis Aligned (Hammer style) or Face-Normal Aligned planar projections.
• Fast Alignment: Quickly justify textures to the Top, Bottom, Left, Right, or Center of a face, or Fit them perfectly to the bounds.
• Aspect Ratio Compensation: Automatically adjust UV tiling to match the aspect ratio of your active material's texture, preventing stretching.
• Copy & Paste UVs: Instantly copy UV offsets, scales, and rotations from one face and paste them onto others.
• Align to Edge: Select an edge and automatically rotate your UVs to align perfectly with it.
• Randomize UVs: Break up obvious repeating patterns on large surfaces (like brick walls or tiled floors) with randomized UV offsets and rotations.
• Pie Menu Integration: Lightning-fast access to all tools via a dedicated Pie Menu (Default: Shift + Alt + U).
• Live Apply: See your tile, offset, and rotation adjustments update in real-time.
