Re: [Nebula-Discuss] rendercontext question

[<ma...@fd...>]

     Hi,

     What I would do in that case is to isolate the "wheel state" in 
some external variable such as "rotationFactor". Wheels objects then 
render them accordingly, using an nAnimator that rotates them using that 
variable.

     The renderContext used in the entire car has that variable set. 
Car's trunk does not used it, but wheels do.

     Hope that helps.

         Marco
