I had already thought of that. Its easier only if you want some limed an unspecific results. But try to break the planet into 3 parts as in the initial examples on page 1.
My last image shows a view of the moon that does not really show the depth of the destruction to the sphere object, if I turned it a little more you would see that the object is decimated down to the core of the moon. DOing it with bump or displacement is possible but not practical for me given the problems with TRO on or off. So there is no displacement in the image now, the sculpt shows great detail though. still trying to work that out.
Also, its a way to learn and use mudbox and maya, which offer more options for specific design in modeling for use in my TG2 work. I more or less am just trying to establish a working pipeline for my self, with the software that I have. The funny part is that TG is the strongest part of this, Maya is the software thats proving to be the real problem.
I have run into so many issues with it (maya), Im near ready to dump it altogether. Its ease of use and functionality with other software (including autodesk products) is near shit. I feel like only the animation portions of the software may redeem it. And the stability of v 2013 is a joke. If I had paid for this autodesk software (rather than the free versions I use) I would be in a rage right now. There are a ton of bugs I have not even mentioned.
edit*
Now that I have put voice to this, maybe Ill look at some other software tonight. Modo 701 is out and the learning addition is only a little more than $100. Have to think about it.
