vue has some features but it lacks in some areas severely.
The star generator is the worse I have ever seen. The glow effect is useless in many situations.

It's clouds can be tweaked to look better but never as good as Terragen. That is why most pictures in the vue galleries use photgraphs of clouds as their backround.

Solid growth trees are ok but suffer from many problems especially when used in ecosystems.

The folks at e-on aim high but always miss the mark usually leaving their software in beta and then moving to the next version.

Support at e-on never answers why something doesn't work and their best advice usually is try the latest beta update.

In short e-on seems under-staffed which causes most of their problems.

As for vue 6 please.... fix vue 5 1st before the upgrade.
