There are some issues with Lightwave compatability that will be addressed with the 4.1 update. If you don't have 4.09 make sure you have that. Walkthroughs are very doable right now so you are in luck
You can make some cool walthroughs by baking your lights.
For now, when you export from lightwave always use the embed objects option. Yes, this means no vertex animation.
Do not use layered objects in lightwave. Wirefusion will not read them properly yet.
When you import a 3d object into wirefusion as a 3d scene, it will use your lightwave camera position, height, and zoom factor.
Don't use surface values or light strengths over 100%
