Hi all,
I have been trying to figure this out for a few hours.
I have a terrain on which I placed a map I brought in from google maps… Now I’m trying to add trees and it gives me the blue marker but when I click no trees appear. I have them loaded into the terrain script panel under edit trees… But the problem is it just won’t place them can anyone help me?
Thanks
I added screen shots…
Also I can’t mass place trees either… I tried that and it didn’t work either…
Thanks
Hm … you could try to re-import the tree prefab / model with a larger scale and / or increase the tree view distance .
Maybe you just don’t see them ?

Hmm well, having just tried out this feature, I encountered similar problems. First I thought it was not painting trees, then when I zoomed in, I saw hundreds of tiny little trees, lol. Another time I exited terrain and chose another object, and then selected terrain again, and then the painting feature worked, :?:
Hope that help.
Hmm, that doesn’t work either… I even tried to create trees from a new project file with a brand new terrain object and still no success???
I don’t think it’s because I don’t see them I think it’s because it’s just not placing anything in the scene… It doesn’t even show in the Hierarchy. Even when I try to drag the tree object into the scene it doesn’t show up… This is strange… Sucks because I’m in the middle of a deadline…
Thanks for the help but are there any other suggestions…?
Any help is appreciated…
Thanks
Okay so if I change the scale and reimport into the prefab I can drip the trees in the scene… I can see the trees but I’s like to be able to paint the trees on the terrain… Instead of hand placing the tree prefabs all over my scene…
Oxl: Your suggestion helped but only partly… Thanks so much but I’d still like to be able to pain the trees on the terrain…
Any other advice?
Thanks again
Thanks guys… I don’t know what happened… Must be a glitch in the Matrix… he-he… But all of a sudden it’s working now…
I have no idea why it’s working now and wasn’t working before…
Now if I can get them to not look smashed and skewed and I’m good…
Thanks…
I’m wondering if it has something to do with the map textures I’m using on the terrain. Is there a texture format that you should not use? ie… png, jpg, etc…?
In one of the tutorials I saw it said something about making sure it’s a raw format…
I was able to get the painting of trees working on a new scene and project but my original project for some reason doesn’t want to pain the trees.
UGHHHH???
Go to the unity website unity3d.com and look under support/documentation/reference manual. It’s very in-depth and answers a lot of questions. 
THANKS GUYS
I got the same problem too . . But i already Have it resolved
Check the Terrain settings - > tree & detail objects - > just ‘mark’ the ( " draw " ) checkbox 
only that
Thank it is perfect
Hello I had such situation with grass on U5.1.1 and in my case, I had object like
ObjectRoot (only transform component)
Object child (mesh filter, renderer, etc)
the solution was to make prefab from “Object child” only and use it as an object for plants.
Wow, this is so noobish, but this was exactly my problem! Thanks for the heads-up!
OH DEAR GOD, thank you very much! +1 Thank you for the solution
I have a problem here. I can insert all models manually, but in the terrain editor, i can paint in grass but no trees ! I thought already on camera distance, terrain options like tree distanse or detail, lightmaps and so on. I cant figure out, what is wrong. … all Objects are there (no matter whitch I put in) because when i bake them, their positions still get counted, but when I paint them as trees, they are invisible. When I put them manually, they are visible… I don’t know what I do wrong … 
Hey Guys, its me again, i did not figure out the problem (yes I did, see Edit) , but at least one solution ! Listen : In my case, I did something wrong on the Quality Settings of Unity, but I don’t know what. I just reseted it on the little icon on the right (look picture) and now, all trees are visible again ! Thank God !
Edit : I figured out the Problem. The Problem was the Maximum LOD Level I changed before on the Quality settings ! If the LOD Level is higher than 2, the trees somehow disapear, also they are still there somehow! Just set the LOD Level to 2 or 1 and everything will be fine !
I had the exact same problem, turns out the opacity setting was at 0, turning it to 1 makes them appear. Problem solved for me.
Finally figured out the fucking problem
It’s due to the objects you’re using
if the objects are from the unity asset store
then
the chance of them working from the tree add system is more likely
but
if you use an outside object or prefab
then you have to drag the object/fab into your scene
and
manually place them
also
unity store has some of the lamest assets I’ve seen
try tf3dm
way better assets and are free to boost xD
I’ve been having this problem recently. I’m making my root/stump in blender, then using 3 billboards and combining them to make my trees. The trees will not add no matter what I do to Unity. I think it’s something about it being partially a blender geometry and using partially flat billboard cubes from unity. It could be the fact that it’s 4 child objects to create a prefab, I don’t know…
Kind of wish it would work. Otherwise, just gonna have to make ‘prefab clumps’.
EDIT: I see what it’s saying now. “The Object could not be instantiated because it doesn’t contain a valid mesh renderer”. This is because I’m using a single empty game object to hold the 4 objects necessary for the tree in Unity. So I guess the best bet for anyone making their own trees (and probably attempting to make billboard trees) is to (if you’re using blender) do everything inside of blender completely and just have a single mesh with UV map…Not as simple as just throwing together a couple child objects in Unity…
