Warangel; (1)Vue 5 doesn't have Mover 5, but it does. There -is- a Vue 5 specific version of Mover 5 on the applications CD in the add-ons folder. But you have to have a valid liscence for Mover 5 to register it and use it. So you will have to buy Mover 5; but what you will get is a serial number keyed into the reg number of the Vue 5 you bought. (2)HDRI is High Dynamic Range Image. Vue5 does image based lighting, which is where you load an image into the atmosphere editor, and the image is 'lit' from calculations made off of the picture you loaded. HDRI is the upper end of this scheme. HDRI images are taken with a special camera, and very detailed image lighting cues are stored in a .hdr file. For stills the effect is incredible; for animation, it's pretty much a waste of time, as it takes quite awhile to render a frame with HDRI, and being in motion prevents you from really seeing the effect. But that's why we have GI and Radiosity to play with, as well..... (3) Doing animation, you definitely want either Vue5Mover 5 or wait until the turn of the year, when VuePro 5 is due out. VuePro has the network rendering ability for stills natively; but you need Mover 5 for the Poser animation and dynamics import. With the Esprit line, Mover 5 provides the network ability as well as the Poser import functions. Vue 5 is cheaper. We don't know the new features of VuePro 5 yet, but it's safe to say the new toys in Vue 5 will be there, so all the lighting goodies will be present, and well as the animated trees (and I assume the metablobs).
