Terrain Brush Off Center

Unity Engine
1

Hey everyone, my terrain brush is off center and im wondering if anyone has any idea why, and how I might fix it.

Here’s an image taken right after a terrain lower click w/ 25 meter round hard brush. (This happens for all brushes, and im using my mouse, i have a tablet too but i though maybe it was interfering so i unplugged it and just used the mouse and this is still the result)

Although it looks small, thats a 25 meter brush! So when texturing the terrain with a 2 meter brush is like completely off.

Thanks in advance for any help! :slight_smile:

First of all, the brush size is not in units. It’s in pixels of the heightmap. So if you have a terrain that’s 1000 meters on each length, a heightmap resolution of 513, and a brush size of 25, your brush will paint features of around 50 meters in size, even though it’s set to 25. I have no idea why they have made it this way, as it’s pretty hard to work with…

But back to your question: Normally when my brush is off centered, it’s because my size is an even number, and pretty small, < 10. I have never experienced it with such sizes, at least not as much as you show on the picture.
It must be because the rounding of the raycast hit they perform is doing this, if they perform such, or something like that. What are the meassures of your terrain, and the position in world coordinates, and the heightmap resolution?

Thanks for the info about the brush! I had no idea. And i haven’t made it any particular way, I’ve just made a terrain of 1000x1000 and 600 high and im basing the scale on a standard 2meter scale. 1000x1000 was what i needed in size and I was just under the impression the brush was in meters my bad.

Terrain pos in world - (-500,-30,-500)
(I tried centering it, same problem)
Heightmap res - 513

So was the Unity developer making the blue brush indicator on the terrain :wink:

Anyways, thanks for the meassures, I will give it a thought in my dreams. Gotta sleep. But strange indeed…

Ya actually lol. Im on windows using 2.6.1 i guess it must be a feature that wasn’t available before 2? I have always had that brush indicator as i’ve always used v2 onward.

It was introduced in 2.6.

Thanks for that information :smile:. Seems I must have imagined it being in previous versions, either way i’ve done the bulk of my terrain editing in 2.6 so that’s most likely why.

So no one has any solution?

Does anyone else have this problem?

The funny thing is, i tried this on my laptop, different project and all, and I still experience the exact same problem…?! Unity devs, whats going on!? Lol

Are you talking about the terrain changing not right under the blue maked spot?
I have the same problem, the terrain change apears southeast of the spot.

No big deal when using with large brush sizes, but extreemly anoying when using small sizes.
I find myself using a brush size of 10 and opacity of 1 the most and the ‘aim’ is always off quite a bit.
(wish I could set default values for brush and opacity to my flavor)

Could it be widescreen related?
