In any order: The tools of my shop to make 3D animations.
PaintShopPro 6.0 : pictures and photo editor and more. I use it to create textures (envelopes/materials) (that's how you can make a cube becomes a wood cube or marble cube or other material in Poser).
PaintShopPro 6.0 Animation Studio : Animations editor. That's how I change an .AVI animation into an animated GIF. Allows text include, etc.
LSX 3.5 : To move from AVI to MPEG format, then reduces animations files sizes..
TextPuppet : To make Poser characters speak. You type the sentence and it generates lips movements and synchronised wave! You nearly have only to record the animation! Incredible but true!
Nero WaveEdit : Waves editor. To create, modify your animation sound track.
UV Mapper : for Poser4. works with the .obj files.
Phi Builder : for Poser4. UV Mapper complement, works from .obj files , creates and edits the Physical hierarchy (.phi) of Poser4.
