I'm new to Crazy Talk and I set a dance animation and at the end I get this (pictured, along with bone structure.). What am I doing wrong?

Looks to me you need to set the connection points, take a look at the manual page that describes it by clicking the picture below.



Dell XPS 8900, Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz, 3408 Mhz, 4 Core(s), 8 Logical Processor(s), 16 GB RAM, - 4 GB GeForce GTX 745, NVIDIA compatible.
Acer Aspire V Nitro Laptop,  2.5GHz Intel Core i5-7300HQ processor with 6MB cache,  256GB solid state drive, 16GB Ram,  4 GB NVIDIA GeForce GTX 1050 Ti graphics.

Here are two issues,
One is Forearm deform, I suggest you adjust the subdivision:

Two is Double Bind Issue, I suggest you set the spirit on your Hip and make sure your double bind was enabled in your separate position.

If you have any question, I will help you, thank you.
