There is only one Lightwave scene file that I can not get to work properly with Lightwave 6.0. This is the "Scenes/FX/Plasma" Lightwave Scene file. It works great with Lightwave 4.0 thru 5.6, but 6.0 can not handle the image sequence. I have heard that bug fixes are coming that will fix this problem, so keep an eye out for patches on www.newtek.com.
