Hello,
Today I started using Unity and after adding a terrain in my scene, I couldn’t move with wasd or my arrows in the scene view in FPS mode (holding right click button). I’m in perspective mode, I tried reinstalling unity, restarting unity, create a new scene, all my keys are set to default, but that still doesn’t work.
Any suggestion that could help me solving my issue ?
Thanks !
In the scene view, under the arrows which shows X, Y, Z axis, there is a little text ISO, click on it and change to Persp. This solve the issue.
The solution to this problem is : You have to find a dropdown arrow on the top right of your monitor(“Layout”).Click on it and select “Default” after that your unity will refresh and your problem is solved.(It worked for me ).
So I spend an hour trying to “fix” this before I realized that my camera actually is moving, just INCREDIBLY slow. If I held down one of the arrow keys I’d eventually move the grid a single pixel after about 5 seconds. It turned out I was just zoomed really far out and the camera moves the same distance at any zoom so it’s really difficult to notice any movement while zoomed out.
hold down right click and zoom out with scroll wheel, that should fix it
Seems the new behavior is that you have to hold right click and then use the arrow keys to move around.
Just in case someone else comes across this post and has the same problem in the editor, try unlocking the rotation in the current direction. It’s the tiny little padlock in the editor view window (#scene). That will allow you to use wasd and the mouse right click. If the padlock is locked then you will only be able to pan around the editor window using the arrow keys and zoom in using the mouse scroll button.
So all I did was read the console error, it showed me the location of the error during my problem with the not being able to move but can scroll and everything else works this refers to mostly not being able to use WASD or move by grabbing the screen even trying to move using shift did not move me, I was litterally frozen, error said ambiguous some thing something, there was a folder in my assests called IgniteCoders that was connected to it, I didn’t know what it was so of course I deleted it, and bam I could move again as if nothing happened, no idea how it got there to begin with probably a package or something I installed. But boy was that frustrating I hope I helped.
Old thread but I bumped into it… I was working with Oculuos rift and had it plugged in yet not their controller in the scene however it still took over any camera and prevented movement.
I unplugged it and turned off oculuos and whammo it all worked again.
Hope it helps anyone else like me who bumped into this old thread. Even though it was not terrain for me.
Have a great day!
At the top right of the scene view there is a tab for editing the scene view camera, in there you can adjust the speed of the camera regardless of what is selected.
In the scene view and on its top-right buttons bar you have camera icon, click on it and then UNSELECT “Camera Acceleration”
I had the same issue and i found a solution for this:
I accidently held Right Mouseclick and used my MouseWheel and this changed my Acceleration to very slow, so use this again and up it to make it fast again 
Hi, bro!
Krch, if you hold down the right mouse button on the stage and start turning the wheel, then you will change the speed at which your camera moves with WASD. You most likely unscrewed 0.001x, at this value, you will not have a camera flying with WASD.
Perhaps they have already given such an answer before, if not, then I hope that it helped)
In Scence view, click on the Camera button and set the Max attr of Camera Speed to 5 and use it as default. This solve the issuse.
i cant move and even use editor at all i can only look in 1 spot an tht all nothing works
I encountered the same Unity bug, and here’s how I managed to fix it! 
The solution was surprisingly simple:
After doing this, everything started working perfectly again! 
If this helps you, please give it an upvote to help others find the solution too!
I had this problem once, and the solution was I was set to 2D mode (Top right of the Unity Editor screen).
Just Click play button(ctrl+P) and switch to Editor (scene view) the free movement automatically starts working again stop the game and start using the Free movement in scene view
