Paint a surface
Paint color directly onto a supported mesh texture with brush size, opacity and hardness controls.
Before you start
Select a paintable mesh in the Material workspace and exit Face Selection or Mesh Edit Mode. Painting requires a supported material and a safe, readable texture/UV setup.
Use the operation
Paint color onto a mesh’s texture with direct brush strokes.
- Open Material Paint from the Material sidebar. If it shows a readiness message, resolve that condition before starting.
- Choose a color and set brush size, opacity, and hardness. Start with a short stroke on a small visible area.
- Inspect the painted region and nearby UV seams. Continue with several controlled strokes, then choose Stop when finished.
Controls and choices
| Controls | What changes |
|---|---|
| Brush controls | Size controls the painted area, opacity controls coverage, and hardness controls the softness of the stroke edge. |
| UVs and existing textures | Show3D can prepare a paint UV atlas for eligible untextured geometry. It blocks automatic UV rebuilding when that would remap existing textures. |
| Unavailable painting | Shared materials, unreadable texture images, unsupported mapping, or unsuitable UVs can prevent painting. Follow the displayed reason rather than replacing the existing texture blindly. |
Try it in your scene
Start Material Paint on a compatible mesh, paint one short stroke, and inspect its edges and nearby UV seams before continuing.
Check the result
Check seams, repeated regions, and adjacent faces to confirm the stroke appears only where intended. Painting changes texture color; use sculpting when you need to change the surface shape.
Practice in Show3D
Open the editor and follow the steps with your own scene.
