Yes- very different programs. I was pretty interested in buying MojoWorld 3- and tried the demo- but it actually turned me off- especially the overly-paranoid "MojoWorld 3" graphic that literally covers every square millimeter of the image when you render! Worst demo software I've ever seen- and no uninstaller, even! I'll stick with what Vue 5 does and my favorite old, and still very useful, Vistapro 4- and wait for the new Terragen to come out.
