thanks vassilios, but i’ll pass. Just not in a mood to learn another application when we have blender 
Holy Crap mpan3, links to other software, in the Other Software forum? what next?
Never limit your toolset
so much as I would love a utopian-software package like blender, all my needs met in one place, for the time being they are not!
Digital Fusion and Houdini also come in flavours for people wanting to learn the trade. Good find Vassilios, I will hold on for the mac and linux demo.
