Hi Drac. I read your piece over on the Daz forum. I can understand the need for keeping things all hush hush. But maybe they have come up with something that all the other apps don't have. Say, I don't know, and this is just pure speculation now, a fully intergrated tetonic plate and gravity simulation module that would allow you to simulate things like continental drift, using the moon, or number of moons to affect tidal patterns. Using tetonic plate and mutiple levels of different ground types to create more varied and realistic mountains, and land masses. The ability to adjust the ph balance to simulate the effects of acid rain of plant and world development? Let's see any other program come up with this!!! David
