Because I don't feel like spending $800 on something I won't use much. All I really need is a way to create fractal dispmaps.
Geofrac 2000, got legit key for MCM2 creators
World Machine
Leveller
Terragen
All of the above create Fractual Dismaps, if I'm understanding you correctly that is.
so how much do these cost? and what sort of features do I get?
Well since google is so hard to use I will enlighten you.
Leveller is probably your best bet more expensive then the rest. But you pay for what you get.
I listed off the links for all the apps that I posted. I hope that helps.
