Painting terrain problem
I'm not able to paint my terrain. I'm able to put some grass and tree but not terrain texture. what is the problem ?
I have the same problem with Unity 4. I cannot paint any texture except the first one. If I select a brush, the blue "preview" on the terrain does not change (it stays at the soft round one) and also brush size, hardness etc don't affect the blue brush anymore.
If I select another texture in the editor, it still paints the first one.
This happens with a virgin project aswell. Create Project. Create Terrain. Add two Texture. Can't paint the second texture.
I cannot confirm that this happens since Unity 4 is out since I believe I have used the terrain since then. Though it could have been the beta.
Bug report is filed.
I'm having this problem too, again, Unity 4.
It seems like any changes I make (brush, texture, brush size, opacity, target strength) don't 'stick'. Changing the brush size should instantly change the size of my brush when I move my mouse over the scene, but it doesn't.
For brush size, opacity, and target strength, you can force this by making your desired changes, clicking on some Game Object that isn't the Terrain, and then clicking back. But this doesn't work for brush (shape) or texture.
Hey Arrow, for me, this somehow magically disappeared after a while. Sadly I don't know if it's anything I did. And it never happened to me after... so I guess, hang in there ;)
The next time I rebooted my machine and started Unity 4 the problem wasn't anywhere to be seen, either - so I think good advice is the old "did you try turning it off and then on again" if anybody runs into this again. I wish I could reproduce it reliably for the sake of bug-fixing but I haven't seen the problem since.
I am having this bug too. The terrain editor is practically unusable

I was having the exact same problem. As absurd as it might sound it's gone after reseting unity to the default layout (Window -> Layouts -> Default)
Now I can paint with all the textures again and the brush works normally.
Nasty bug, but this seems only reliable solution I've seen. Thanks.
Still works. This was a frustrating problem. Thanks!
Anyone submit this as a bug with Unity 5?
Thanks for the answers.
This is completely unacceptable. It's been 4 years and this is still a problem?????!!!!!!! I'm loosing 40-50% of productivity fighting all these editor bugs. I'm not happy that I paid 3k for a pro license and deal with these bugs robbing me of profit while I pay Unity 1500 bucks a year. This is bullshit.

Did you try loading a texture first into the texture boxes?
Read through this page for step by step instructions on how to paint textures onto your terrain...

I had that Problem too, but after changing every possible option I realized that the slider "Target Strength" was set to 0 so I had no Chance to paint anything.

I had this same problem of not being able to use paint or elevation tools for the terrain editor, and rebooting didn't work. Window, Layouts, Default fixed the bug! Also make sure opacity is 50+ or you might not see the brush working.

I ran into the same problem. Rebooting did the trick once and now it's back to "Texture painting? I can't let you do that Dave..." I'll try to open my project on a different machine with a fresh Unity install, let's see if the bug persists. My version is 4.1.5f1 btw.
Update:
I upgraded my Unity to 4.2.0f4 with no apparent effect. Editing older projects functions without an error, new ones come up with the known issue. After opening my project on a different computer with a fresh Unity install, I got suprised with a completely working project. I'm now copying the fresh install onto my regular working machine, maybe it'll help.
Update 2:
Copying the functioning installation over my faulty one did not result in the desired effect. Im now going to export the projects terrain content to an older, working one
Update 3:
The exported data functions just as wanted. For now im going to paint the Terrain in a different project. After finishing, it will be reimported to my original one. Damn unpractical solution...
