Settings
- Foreground Image - Select an image for the foreground.
- Browse' - select an image
- Clear - clear current image
- Use Foreground Image - uncheck this to turn off the foreground image without changing any other settings.
- Use Edge lines for foreground (SketchUp only) - uses the SketchUp edge lines as a foreground overlay.
- Use Multiple Mode - merge images using Multiply Mode
- Treat White as Transparent - any white in the image is treated as fully transparent.
- Stretch to fill screen - the foreground image will fill the entire screen\*
- Tiled - the foreground image will be tiled across screen. This is good for masking patterns.
- UL, UR, LL, LR' - the foreground image is place in a corner of the rendered image - useful for logos.
- Lock Aspect ratio - When stretching the foreground image, it will not be distorted. (And if may not fill the entire screen).
- Use as mask - the intensities in the foreground image will change the intensity - but not the color - of the rendered image. In mask mode the pattern is applied only to the geometry and not to the background.
- Scale - for tiled and centered, allows you to make the image larger of smaller.
- Blend Foreground into rendering - makes the foreground image partially transparent. Less = more transparent. More = Less transparent.
- Apply - redisplays the rendered image with any changes you have made.
Notes
- Use .PNG files when possible. Compression artifacts in .JPG images may effect transparency.
Use with Edge Lines

Sketchy Hidden Line from SketchUp
By saving an image of your SketchUp model in Hidden line or with Sketchy Edges, you can use the line image as a foregorund image, which will add the edges to the rendered image.
Multiply Mode According to Photoshop help...
- Looks at the color information in each channel and multiplies the base color by the blend color. The result color is always a darker color. Multiplying any color with black produces black. Multiplying any color with white leaves the color unchanged. When you’re painting with a color other than black or white, successive strokes with a painting tool produce progressively darker colors. The effect is similar to drawing on the image with multiple magic markers.
