This is an all-in-one avatar realism tool which is designed to be handy and affordable for creators and customers alike, and it's a result of a long research and many comparisons of real life human bone scales versus IMVU avatar bone scales.
Please notice that IMVU never released a guide for the official scale of in-world rulers - this is just my take based on my research, but I tried to make it as anatomically realistic as possible.
Here is what you receive:
In-world signs to guide in understanding the differences between IMVU avatar and the real life human anatomy.
Rulers - in metric centimeters as well as imperial feet and inches. These are improved and updated versions from my previous portable measures. Since these are not portable but furniture, they won't shrink or grow with scalers and have an extra benefit.
"X-Ray Box" to reveal the transparency glitches within IMVU.
Eight test poses to see how IMVU body parts work in certain extreme positions of human body. Some are animated. These are especially good for meshers to reveal the small details that might need some improvement and won't show with IMVU default animations. Skinners may also find their work easier with some of these poses.
