Enhanced Vertex Color Tool v3.0 !!

A Blender addon that provides advanced vertex color editing and visualization tools. It enhances the default vertex color workflow with powerful operations such as gradients, randomization, AO baking, channel management, and inspection.

For blender 4.5+

Changelog :

• v3.0.1 and 3.0.2 - Fix of issue at installation for some

  • Toggle between Vertex Color and Material viewport display.
  • Switch between Flat and Studio lighting for better visualization.
• Fill Tools
  • Fill with custom color, black, white, or single channel values.
  • Per-channel fill with adjustable intensity.
• Gradient Tools
  • Linear and radial gradient fills.
  • World-space, local, or active-object-inherited direction.
  • Invert gradient, global/local control.
  • Interactive Trace Gradient directly in the viewport.
• Randomization
  • Random fill across entire mesh, per connected component, or per UV island.
  • Optional normalization of values.
• Channel Management
  • Clear channels to 0 or 1.
  • Invert channel values.
  • Switch channels (e.g., R → G).
• Ambient Occlusion Baking
  • Bake AO into a chosen vertex color channel.
  • Control resolution, UV map, and progress tracking.
• Inspection Mode
  • Preview a single channel as grayscale.
  • Accept or discard changes after editing in inspect mode.
  • Special tools available while inspecting (fill value, randomize, gradients, etc.).
