Shadows

One of pwCatch's most important attributes is the ability manipulate shadows. Using pwCatch, you can cast shadows into the scene with an invisible object, or have an object receive shadows without its surface being visible.

  • Shadow Mode
  • Shadow Color
  • Shadow Strength
The Shadow Mode property controls the shadow casting and catching features of pwCatch.

Selecting No Shadows will cause the surface to neither cast shadows nor receive shadows.

Catch Shadows will cause the surface to receive shadows from other objects, but be invisible otherwise. Note that you can have a surface that catches both shadows and reflections by turning on Catch Reflections as well.

Invisible, but Casts Shadows will cause the surface to cast shadows onto other objects, but be invisible otherwise.

In the above image, the green object is set to Invisible, but Casts Shadows and the yellow object is set to Catch Shadows.

The Shadow Color property allows you to change the color of any shadows caught or cast by the surface.

This property can be mapped using the Surfaces tab, so you can change the color of shadows according to a texture map, like a stained glass window.

In the above image, the green object is set to Invisible, but Casts Shadows.

Shadow Strength controls how opaque the shadows caught or cast by the surface are.
