Terrain brush not where cursor is.

Hi,
The terrain paintbrush/raise/lower brush is not synced up, for lack of a better term, with where my cursor is. My cursor can be clicking away in the middle of the screen with nothing happening, and then I zoom out and notice the corner of the terrain is risen/lowered/textured etc. The effect is lessened with larger terrains but there is still a fair distance between the cursor + brush.

I have reinstalled Unity to no effect.

Here are two other threads from March and May 2012 with people experiencing the same problem.

This is really frustrating. I'd really appreciate any advice.

Thanks,

 

After struggling with this for a day or two, i was finally able to get it to work again by simply unchecking the terrain collider in the inspector and then turning it back on again.

 

5 years later - thank you!!

 

Thank you for this! For me it did not work out just by unchecking, I am not sure how I did it, but it eventually worked, after I did it 10 times and reset the Terrain Collider block, and unchecked again. Really annoying problem to say the least...

 

I had a similar problem after changing the resolution settings with the newer Unity Terrain tools. Restarting Unity seemed to solve it
