The best thing I have seen so far is making a primitive object and assigning it one of the fire or smoke textures, then animating the texture on it. That said, it has been (sorta) confirmed that there will be NO particle generator in Vue Infinite, and Vue 5 regular doesn't have on either. However...Vue Infinite supposidly has better support for python scripts, and maybe some clever developer will develop a sort of particle system using python. It would probably have to be a specific python script for Vue though because Vue will not work with Poser's python scripting. For example, Vue will not import particles made with Megaform, a python particle plugin for poser. It sorta works but Vue will only import the first frame of the particles, even though they work fine in poser. Short answer...use an animated texture and don't hold your breath for a native particle system for Vue.
