Re: FLASH: Rotating Globe

[Jayma]

John!


I just have to say... Thank you!  I never anticipated such a response from

a (what I thought) was a simple question to simplify a 3D graphic that I

was asked to create by a client.  It went to a different world, never

answering my initial question (and I am still not sure that I can get the

graphic down to a usable size).  But thank you for addressing my initial

question.  I will probably just redesign it in a simple method, but I hate

having to give up the mesh design.


Jayma.
