Hi, I will work on a demo version soon. I just need to figure out what should be limited and what shouldn't. To animate the primitives, you can usually just animate the Z coordinate of the 3D shape: it will give the effect of a rising vapor. There should be some tutorial in the next 3DXtract. About the price, you can already buy Deeper, Baker, Primivol and Replica at a discount price. Each time a plugin is bought, you're elligible for a discount on all the other one. To get the greatest discount, buy the cheappest one first. For these 4 for example, it would be 15+29+29+39=112$ when buying Deeper first. I think a discount is more flexible than a bundle: every new plugin will benefit from this discount, and you can just buy the one you want or need.
