<bumpmap "ImageFile" | "source">
This language element may be used inside a <trait> block.
This allows you to specify an image already loaded (or to be loaded) into F/x that will be used to disturb the apparent surface angle of any object that it is attached to. For "ImageFile", the complete path and filename must be specified. If the image is already loaded within F/x, then it will be used from there. If not, it will be loaded and then used.
If you specify the explicit "source" command instead of an "ImageFile", the currently assigned source image will be used as the bump map. An additional benefit of this approach is that in the TimeLine, you can use an animation as the source input to the raytrace operator, thereby allowing you to use an animated image as a bump map.
Using F/x's Save Project menu item in the File Menu in conjunction with the various types of image maps can very useful, because it saves the settings of all the effects, as well as saving all images that were loaded when you use Save Project.
You can then later use Load Project to immediately load all of the components of a ray tracing project, including all image and bump maps. Images that are not loaded at trace time will be automatically loaded, however.
