UVManipulator System

Overview

A Unity tool for batch UV manipulation across multiple renderers using a single shared material. Each renderer gets its own MaterialPropertyBlock overrides, allowing independent UV and color control without creating unique material instances.

Core Functionality

Single Material Workflow

• Assign one target material to the component
• All renderers use this shared material
• Per-renderer overrides applied via Property Blocks (no material duplication)

UV Channel Control

Controls three separate UV channels independently:

• Base – main texture UVs
• Normal – normal map UVs
• Mask – mask/alpha UVs

Each channel has its own:

• Offset (position)
• Tiling (scale)
• UV method (UV Mapped, World Pos, Polar, Screen Space, Time Sequence, Custom Math, Procedural)

Renderer Management

• Automatically finds renderers in children
• Filter by layer or specific material
• Individual enable/disable per renderer
• Visual selection system for batch operations

Selection & Randomization

• Selection modes: Select All, Random %, Select from Unselected only, Invert Selection
• Randomize Selected: Applies random UV offsets, tilings, and colors to chosen renderers
• Randomization controls: Configurable variation ranges for position, size, and color
• Auto-randomize on Start: Optional runtime randomization

Color Control

Per-channel color properties:

• Tint
• Brightness
• Contrast
• Hue Shift
• Saturation
• UV Blend Weight (base ↔ normal blending)

Per-Renderer Flexibility

Each renderer can either:

• Follow Master – inherit global UV/color values
• Custom – use stored per-renderer overrides

Summary

A single-material, multi-renderer UV control system that enables independent UV manipulation, randomization, and color adjustment across selected objects without creating material instances—ideal for achieving visual variety while maintaining render efficiency.
