Hello MrSparky!  I'm just getting back in from doing real life tasks, and now am rebuilding the RAID mirror (the motherboard has a glitchy HD socket and drops port 0 occasionally).  I'll have dinner while the mirror rebuilds, then back to it.

     Most for-purchase AVI packs use a compression codec, in particular, it's generally a 32bit codec.  If your 64bit computer doesn't have -or can't run- that codec, then the AVI won't work.  You can load the AVI into a video editor, and re-save it in a different codec, or without compression if it's small enough, and then use it.

     Besides a complete demo prop, I will include mt5 material files which the pack will unzip to the material part of your runtime library.  To apply such a material, enter the material room, and select your model's material zone.  Double-click the library mt5 file (or drag-n-drop directly from library palette to the item/zone in the scene), and you're done.  I'd be glad to help you with any particular project you've got going.  The sreenshots of the material room and object parameter settings should help.

     It is possible to light the scene with no Poser lights on, but to get natural specular highlights and such, I much prefer to use both self-illuminated meshes (for the myriad little lights) and use a few Poser lights in the scene to get best results.

Poser 12, in feet.
