I needed a unique “artifact” for my next Nursoda story, so, with fear and trembling, I fired up Blender, created exactly what I needed starting with an empty screen, exported it as a 3DS file (a file format used by Autodesk 3ds Max, a $3,500 program — Blender, otoh, is free), and loaded it into Poser (you can get more info on Poser and Blender on my site under the Art/3D menu).
Now, it’s not a complex item, and it doesn’t have any fancy surface textures. But, if a 67 year old guy who never tried computer graphics of any kind until a year ago can do it, you can too!
Here are two sections i cropped out of larger images using the prop. In the darker one, I was actually able to get it to glow and cast a red light into the face of the acolyte wizard holding it!!
