Within the Hollywood FX installation folder, you will find the Lightwave Content folder that contains sample objects and images to use.
Within the Images folder, you will find the MAPxxx targa images. These are important because they can be used as proxy images when created your own 3D objects. Wherever you use these images, the Importer will replace them with Host Track video references. So, if you want an object to display Host Track 1 (the first video source in a transition), simply map MAP001.tga onto the surface, and when you import the object, it will be replaced with Host Track 1.
When creating objects that you will import into Hollywood FX, you should follow these rules:
Objects should consist of 3-point and 4-point polygons only. It is recommended that you only use 3-point (triangles) polygons to make sure that all polygons are convex.
If you want to use the object in Pro-ONE for realtime, you should use as few polygons as possible. As a general rule, the entire effect should have less than 1,500 polygons to ensure that it will playback in realtime.
Hollywood FX uses only a subset of the features of Lightwave surfaces. Generally you can adjust base color, transparency and luminosity.
For textures you can use any of the normal projection mapping modes (Flat, Sphere, Cylinder) from Lightwave 5.x.
