Yes, it's quite user-friendly. You simply pose your character, adjust the vertices, and Weight Shaper does the weight painting. It's straightforward and ideal for those new to this area.

Yes, you can apply the optimization multiple times. This is particularly useful if the algorithm didn't converge in the first attempt, possibly due to a low iteration setting. Multiple runs allow for further refinement until the desired result is achieved.

Yes, after each optimization, the algorithm automatically normalizes weights to ensure balanced and consistent results across the model.

The add-on's performance largely depends on the algorithm's settings and the number of vertices adjusted. More vertices and higher precision settings can increase processing time.
