🆕 New in v3.1.4

Region Fill → Define decal areas using Add (blue) and Subtract (orange) regions drawn directly in the viewport. Generate decals inside complex shapes with multiple loops, hole-cutting, density control, clustering, boundary padding, and seed-based repeatability. Fully integrated with material slots, overdraw gates, grouping, and object filtering.
Object Filtering → Paint decals only where you want. Add any actor or tag groups to a live filter list, switch between Avoid Listed and Only Listed modes, and fine-tune the allowed area with adjustable padding. Deleted or renamed actors auto-purge from the list for a seamless workflow.
Added Debug | Overdraw tools → visualize decal stack density with a live heat-map grid, adjustable cell size and thresholds, plus soft and hard gating modes to warn or prevent excessive stacking.
Spray Paint Mode → is a new paint mode that drops a one-click burst of randomized decals within your brush radius. Choose between Ring for rim based placement and Poisson (blue-noise) distributions for fast, natural-looking sprays.
UI Focus Material Only → Toggle switch to display only tag filters and material slots for an uncluttered UI.
HUD Overlay → Viewport display of current slot, tags, weight, brush radius, and mode currently being used.
Per-Slot Max Spawns → Limit decals per material in a single stroke for tighter control.
Performance & workflow tweaks for smoother painting and cleaner feedback.

🎨 Key Features

Brush-based painting → Adjustable radius, spacing, scatter, and density.
Live viewport previews → Ghost decals, brush rings, and spacing guides.
Smart erasing → Shift + LMB removes decals within the brush radius.
Randomization controls → Scale, rotation, and weighted materials for natural results.
Height, slope & edge filters → Precise control over where decals appear.
Overlap prevention & limits → Avoid stacking and set per-stroke or total caps.
Projection axis selector (X/Y/Z) → Perfect for floor, wall, or ceiling alignment.
Grouping system → Auto-organize decals under group actors for a clean Outliner.
Config management → Save, reload, or reset brush settings instantly.

🏷️ Tagging, Grouping & Shuffle Tools

Tagging System → Assign tags per material slot for quick filtering and organization.
Grouping by Tags → Automatically organizes decals in the Outliner using Active or Forced Tag modes.
Shuffle & Normalize → Randomize tag weights for natural, non-repetitive results.
Auto-Naming Slots → Material slots inherit names from their assigned decals — rename or sort alphabetically anytime.

🧭 Precision Placement Tools

Angle Snap (Alt) → Clean, repeatable path runs with user-defined angle steps.
Vertex Magnet Snap (V) → Snaps path endpoints to nearest mesh vertex — great for edges.
Anchor Options → 9 anchor points for stable scaling and consistent projection.
Path Layouts → Fit modes (Spacing, Stretch, Even Count), multi-lane stamping, and jitter controls.
Anchor Scaling → Pin decals by center, side, or edge for directional control.
Binary Rotation & Scale → Alternate between two defined values (e.g. ±90°, ±1) for structured randomness.

📊 Optimization & Feedback

Decal Counter → Displays accurate totals per level or sub-level.
Hidden Surface Toggle → Allow placement on hidden actors for debugging or previewing.
Sorting Order → Per-material control over overlapping decals.
Max Scene & Stroke Limits → Fine-tune performance and output.

🆕 v3.1.4 中的新增功能

区域填充→ 使用直接在视口中绘制的添加（蓝色）和减去（橙色）区域定义贴花区域。通过多个循环、孔切割、密度控制、聚类、边界填充和基于种子的可重复性在复杂形状内生成贴花。与材质槽、透支门、分组和对象过滤完全集成。
对象过滤 → 仅在您想要的位置绘制贴花。将任何演员或标签组添加到实时过滤器列表中，在避免列出和仅列出模式之间切换，并使用可调整的填充来微调允许的区域。删除或重命名的演员会从列表中自动清除，以实现无缝工作流程。
添加了调试 |过度绘制工具 → 通过实时热图网格、可调整的单元格大小和阈值以及软门控和硬门控模式来可视化贴花堆叠密度，以警告或防止过度堆叠。
喷漆模式→是一种新的绘画模式，可在其中一键突发随机贴花你的画笔半径。选择环（基于边缘的放置）和泊松（蓝噪声）分布，实现快速、自然的喷雾。
仅 UI 焦点材质 → 切换开关以仅显示标签过滤器和材质槽，以实现整洁的 UI。
HUD 覆盖 → 视口显示当前槽、标签、重量、笔刷半径和当前使用的模式。
每槽最大生成数 → 限制一次绘制每种材质的贴花，以实现更严格的控制。
性能和工作流程调整，实现更流畅的绘画和更清晰的反馈。
