I am having a great time with the new FLASH CS4 BONE TOOL , here is an animation project started a while ago & I was waiting for the incredible new animation tools of Flash Cs4 to bring it to life , here are a few pix showing how the bones are applied and some animated test video of the character in action. A full bone tutorial will be on FLASHARTIST.ORG very soon. In the meantime all I can say is that Flash animators will enjoy the new version of Flash more than the previous updates for all these new features.

Hello.
I am using flash 8, and I cannot find my gone tool. The online held does not even recognize the word bone. Am I doing something wrong?
Hi ted,
the bone tool is only available in the latest version of flash CS4
