Load file Use loadfile to load an animation library onto a existing cast member. If you need multiple motions then export two versions of your file. One with just the model with bones, the other with animation in groups. For the exported file with just the static model turn on all export options except for animation. For the animation file only have animation checked.
Flipped normals Stay away from any kind of procedural texture.
Procedurals don not use pixels in a bitmap, meaning if you zoom in close on a model you will not see any pixelation in the texture. This may cause the model to look inverted. Two Sided materials Two sided materials will not export to W3D format. Also, the exporter will not return an error message when exporting a two sided material to W3D. Fullscene export hidden objects All hidden objects will be exported as a visible object when exporting to W3D. If you do not want an object in your scene to be exported, we recommend that you delete this object from the scene. Default lights When creating your own lights do not use the word default in the name.
