I have both Truespace and Ligtwave. With truespace you need to have another app which is free in order to make things work in Poser. Scaling things like that. With lightwave you do not need to have another app. It takes Poser objects perfectly. Morphing in Lightwave is the easiest of any app I have. Both Lightwave and Truespace have excellent support groups. Lightwave is respected in the gaming, TV and movie industries. Truespace is not. The poser Pro Pack has a plugin for Lightwave but not for Truespace. If you want one of the top apps Lightwave is the way to go. As far as learning to model lightwave is much easier than truespace in my opinion. ron
