i have to admit I love atmospheres in Vue regardless prehistoric or not, this one is splendid!!!!!! I dont like Vue Esprit trees that much but from how you positioned them and angled them they dont look bad at all....good job.
It is - but don't be put off by that. Its actually quite easy to use. Bryce, while nice because it's still free (i believe) there is ZERO support for issues because the team that was working on it quit. So there will be no fix patches etc.
