Paint over existing textures

If your model has already been textured outside of the 3D Paint Tool, you can add paint to those textures using the 3D Paint Tool.

If file textures were used, the 3D Paint Tool automatically detects them. You can paint over them immediately without assigning textures. The textures are copied automatically and sized to the nearest power of 2. The originals are not overwritten.

If non-file textures were used, or if the texture placement was edited, you must first convert the texture to a file texture.

To convert the texture to a file texture

1. Select your model, and then in Hypershade, Shift-click the shader attached to the model to select it too.
2. In Hypershade, select Edit > Convert to File Texture (Maya Software). Maya converts the texture to a file texture and automatically assigns it to the shader. You can now select the 3D Paint Tool and paint on the file texture.
