V.I.P 5.7 5.6 Plugins Paint decals like foliage, with spray, paths, and region fill for total control! v3.1.7

New in v3.1.7

• 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, instanced level 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.
