Hello Unity users et. al.
I am learning Unity-Pro by doing the tutorials and building simple terrains and practicing with the tools.
About 30% of the time when I build a terrain (an island or some such to play with) the First Person Controller seems to randomly start falling thru the terrain.
I’m building the terrains with no changes to the resolutions. They are not imported – nothing fancy. Just something to use the tools and such on. I’m not changing the parameters on the FPC and no changes to the scripts.
I drag the First-Person-Controller up. I sometimes use the daylight water by dragging it up – sometimes not. I build a light map. I’m changing none of the parameters in the FPC – just trying to get the hang of the terrain tools, and see how everything is supposed to look.
So why does the FPC randomly, suddenly start falling thru the terrain ? And once it does it, it seems to be unfixalbe. I have to destroy the terrain and build another. (I am getting way good at the terrain tools, though … hehe.) Major frustration here…
Never heard of that issue before.
But I suggest that if you make a terrain and the fpscontroller falls through, save the project folder and send it in via Report Bug.app, so that we can take a look at it.
I agree it seemed very odd to me too; and it’s so odd that it seems unpredictable. I’m using only the default setup with the Standard and Pro Assets. I’ll bundle it up and send it tonight when I get home.
Thanks so much 
Spike
As I move thru learning this software I’m just amazed at how robust and flexible Unity really is ! Wow !
Thanks Unity Support for helping me learn.
I’ve hit this problem too, very strange. Any update on this problem or on its solution?
I’m having a similar problem but with aniamted characters.
I created a terrain, created some cubes and spheres, gave them “rigidbody” components then ran it. these basic shapes worked perfectly - spheres fell to earth, stopped then rolled down hills etc
But I then decided to a add a Character - Lerpz. He didn’t have a “rigidbody” so I tried to add it but a warning message appeared “Losing Prefab” ?? I couldn’t see a prefab so went ahead anyway. After running, Lerptz fell to earth … and continued on through!
I’m not sure what went wrong, obviously adding the Physics components removed something important but I couldn’t work out what? Or maybe scaling up Lerptz by 500 times to make him large enough to see might have caused it? I tred another animated mesh and the some thing happened.
any help?
Thanks
The Lerpz object has a CharacterController, which isn’t designed for rigidbody physics. Try removing the rigidbody, and if you want gravity, add a downward movement to the CharacterController with its Move function as you move the character around.
If the very bottom of your character controller is below the surface of the terrain you’ll sometimes just fall right through.
I’m a little confused. I dont want a First person or Third person perspective, I want a God-view, looking down on all the little characters running around, falling over each other etc, all controlled by Physics.
I’m a newbie, so be kind, I’m reading through the docos but cannot find much on RTS.
Thanks any help.
Additional, ok, I will need a 3rd person camera view but without the character attached?
Hey! I had the same problem when I started. All I did was import some terrains then made some. I just kept doing that and it worked. Just keep doing what you’re doing and it’ll fix itself.
OldCrow - God View IS first person - it just means you are looking through the camera with no character that you are controlling. Read the first part of the FPS example project on the site (that’s first person shooter) and you will see how to set up that script and camera. If it is too low for your “God View” then you can adjust it.
ok, I’ve read a bit more of the tutorials, CharacterControls should be used for self powered things, although I’m thinking gravity should be part of that? hmmm, will read some more.
