To make Machinima movie using Second Life Avatars is NOT suitable for CrazyTalk 8 3D.
You capture photos from your Avatar and bring it into CT8 3D, it then has its hair and clothes removed.  So how can you match it up once LipSync has been done, with the original Avatar.  YOU CAN'T

Also using CT8 3D eyes, the whites take on the hue of the skin colour so turn brownish.

CT8 2D is virtually the same as CT 7.  If there is a difference, I was not able to see it.

CT8 3D works fine IF you use the Avatars supplied but that is no good for movie making unless you get a body from iClone.  Which I do NOT have.

Opinion?  Was a let down and a waste of money.
