Nexus Vertex Painter
This is a powerful, artist-friendly tool to paint vertex color channels (RGBA) directly in the 3D editor. It is designed for Level Design, Texture Splatting, and Shader Masks, offering a workflow similar to industry-standard tools like Unreal Engine or Substance Painter. --- Key Features: --- Paint Modes: Add, Subtract, Set (absolute value), Blur/Smooth and Sharpen to blend colors organically. Brush Stencils (Alphas): Drag & drop textures to paint complex details like grunge, cracks, or leaves. Uses Triplanar Projection to wrap seamlessly around corners. Smart Masking: Automatically mask your painting by Slope (Angle). Perfect for painting grass only on flat terrain or moss only on steep walls. Procedural Generators: Apply global effects with one click: Noise, Top-Down (Snow/Dust), and Bottom-Up (Rising Water/Gradient). --- Production Workflow --- Non-Destructive: Painting creates a modifier node, keeping your original .glb or .tscn files untouched. Bake to Resource: When you are finished, click "Bake" to save a permanent, game-ready .res file for maximum performance. Revert: Changed your mind? Revert the mesh to its original import state with a single click. Safe: Full Undo/Redo support. --- Pro Controls --- Visual Feedback: The brush cursor projects physically onto the mesh, ensuring visibility even on transparent or unshaded materials. Includes a visual Strength Meter. Mouse Shortcuts: Ctrl + Right Click + Drag: Adjust Size & Strength. Shift + Right Click + Drag: Adjust Falloff (Hardness). Keyboard Shortcuts: X and Z/Y to toggle Blend Modes, 1-4 to toggle Channels. Ctrl + Z: Undo Ctrl + Shift + Z: Redo --- Support --- Need help or want to share your work?
