= SYMPTOMS =

An animated transparent object causes shadows on a reflective object that it passes.

= CAUSE =

Raytrace depth value is too low.

= RESOLUTION =

Increase your raytrace depths (for reflection and refraction) in render options (or just one trace depth for the Softimage renderer).

Reflection and refraction limit the number of surfaces a ray can reflect or refract through. Setting them too high can slow down a render, especially if you have multiple reflective objects reflecting each other (such as a mirror facing a mirror effect).

= STATUS =

This behavior is by design.

= REFERENCES =
