The animation is imported from Poser6 using the TransPoser.  While the rendering speed of Poser6 is slow, the preview speed of the animation is much faster with Poser6.

How can I have a faster preview speed?

Core2 Quad Q6600.
Windows Vista 32bit

NVIDIA GeForce 8500 GT

Thank you

 Carrara captures/shows more visual information than Poser so it uses a different scheme for animation preview .  The best, fastest method is more like doing a RAM preview in a video editing application. So, the fastest preview in Carrara is to actually render the file using one of the Draft render options for verifying motion and movement. 

Thank you Mark,

The rendering speed of Carrara is very fast.

However, the response of the time line is slow. It is not easy to move to a frame (for instance, move frame from 1 to 50) because of the slow response.

Is it hard (possible but time consuming) to arrange poser animation in Carrara ?

 Actually I do very little character animation in Poser anymore because it is so easy to animate in Carrara. I will use Poser for animaation if I need to use the walk or talk designer, however - especially talk designer. It is pretty easy to create a walk cycle in Carrara and use the Non Linear Animation tools to save it as a clip and then use it over and over again.

CP5 has Animation tools? How does this work?
Any tutorials on how to do this?

Thanks!

 C5 can animate very well but it doesn't have the Non-Linear Animation tools that C6 has to create looping cycles.

In C5 you can create a set of key-framed animations that represent a single walk cycle and then duplicate the keyframes in the timeline to get some continuous motion, however.
