In Vanishing Point, the Stamp tool paints with sampled pixels. The cloned image is oriented to the perspective of the plane you’re painting in. The Stamp tool is useful for such tasks as blending and retouching image areas, cloning portions of a surface to “paint out” an object, or cloning an image area to duplicate an object or extend a texture or pattern.
To prevent the strokes from blending with the colors, shadows, and textures of the surrounding pixels, choose Off.
To blend the strokes with the lighting of the surrounding pixels, choose Luminance.
To blend the strokes with the color, lighting, and shading of surrounding pixels, choose On.
Select Aligned to sample pixels continuously, without losing the current sampling point even when you release the mouse button.
Deselect Aligned to continue using the sampled pixels from the initial sampling point each time you stop and resume painting.
To paint continuously from one plane to another, open the Vanishing Point menu and choose Allow Multi-Surface Operations.
To confine painting to the active plane only, open the Vanishing Point menu and choose Clip Operations To Surface Edges.
