Hemmm... The roller coaster is Amateria (and that's definitely one of my favorite moments of Myst III toodiafero wrote:Can we get the crazy roller coaster ride in the sphere, from completing the age? *pretty please*?

Right now I'm still in Mechanical and don't want to recreate Amateria... It's waay too big.
Speaking of Mechanical... I finally exported the Age to Uru.
I ran again in a big problem with the interior of the fortress...
In realMyst, go to Mechanical, turn the fortress 90°, then come back to Sirrus' room.
Look through the window...

I looked left, but when you look straight, you only see the big gear in the water.
Got a little idea of what's wrong ?
Now let's have a look in my version of Blender. The big camera is where you should be looking from.

[EDIT - accidentally deleted picture. Whoops ! Imagine the big camera a few meters away from the window position]
Hemmm... Question: how comes we see the big gear, and not the small bridge and the link-out room, since these should be aligned with the fortress base and the north island ?
The answer is: visregions. The inside area of the fortress is nearly twice the outside, so they used a clever trick to hide the outside while you're inside, and vice-versa.
This way it seems to fit in.
I think my version of the fortress is also too small (comparing to the islands nearby). I think this might come from the map I used.
But now it is really hard to know the exact size to make sure everything fits in.
I could use visregions as well, but it wouldn't be fine in Uru... Especially if a player can see his friend floating near the fortress wall, or if the player creates markerquests...
