Godot Vertex Paint Tool

Tool functionality

• Painting RGBA channels into Mesh.VERTEX_COLOR and Mesh.ARRAY_CUSTOM0-3
• Painting separately for each color channel
• Bunch of paint blending modes (set,multiply,screen,darken,lighten,
  difference,exclusion,overlay,hard light, soft light,color dodge,linear dodge,color burn, linear burn)
• Contiguous mode, gives you opportunity to paint on separate mesh clusters (non-connected geometry groups in clusters)
• Using textures as masks for painting
• Tolerance and Normal tolerance to paint from specific angles on surfaces.
• A couple (in progress) tools :
  • Merge meshes (Merge selected mesh instances into one mesh)
  • Split mesh by surfaces (Creates a copy of each surface as different mesh)
  • Split by clusters (Each non-connected geometry to separate mesh)
  • Autoskin (In progress but works somehow)
  • Bones weight paint (In progress too, i need to figure it out better)
• Reading uniforms from shaders to have better experience.
• Demo version has been obfuscated, but included onre "tarr 8 shader", that allow you to paint 8-textures on mesh by using texture array. And all main features.
• Paid version include everything clear and readable. (And gives you better karma)
  • Include tarr 4, tarr 8, tarr 12 and tarr 16 (Number mean textures per vertex)
  • Non obfuscated code

This tool in development and will be improved and updated with time.

Install as any other addon : unzip and move "addons/vertex_tools" into your "addons" folder. After open project settings and enable vertex_tools addon.

To start painting, select your MeshInstance3D And press this button on the bottom dock :  

Buttons

• "Vertex color/Vertex Custom 0-3, Bone Weights" - This is data channels to paint.
• "Rgb, R, G, B, A" - Color channel to change
• "Set, Multiply, etc.." - how new color behave with already existed color 
• "Base,Square,Real" - View modes on model, Base - mean show raw colors, Square - mean raw color * raw color, Real - mean show only changable area.
• "Masks" - List of masks to paint with
• Two colors to paint, Hold alt to use second color.
• Brush radius - Well, how big your brush is
• Brush strength - How strong your brush is
• Tolerance - should be tolerance to color under mouse
• Normal tolerance - Paint on verticies with similar normal direction like under mouse.
• Contiguous mode - Paint on connected vertex clusters
