Thanks for Reminding me Paul, I forgot about the privacy settings on YouTube.

Right now I have Carrara 6 Pro, to upgrade to Carrara 7 Pro it costs $169.95.   

I'm waiting to see if a sale/discount comes along so I can upgrade.

When I upgraded from Carrara 5 Pro to Carrara 6 Pro, with a coupoun + sale it cost me around $75 which was a fantastic deal.  I'm waiting for a similar upgrade path.

I'm going to try and use the built in particle emitter to throw sort of dust in the air and disappear over time.

That way I wont have to worry about adding the dust trail in post.

Once I get the renderfarm fully operational with all the PC/Laptops I'm putting in place.  I dont mind sharing Render Time.

The end result will be 5 x Pentium 4 Hyper Threading PC's and  3 x Laptops with Dual Core Processors.
