Terrain Tree Placing Not Working

No one answered this question on Unity Answers, and since this is a question for my 7dfps game, I REALLY need an answer.

I have a terrain in the game world. I go into placing trees mode with the Terrain Toolkit, and I make a new tree in there, using a prefab I made from a model. I select it and mouse over on the terrain. The blue circle is there, but when I click, nothing happens. Not a single tree gets placed. I go over to the console and it says:

The tree medium tree 1 couldn’t be instanced because the prefab contains no valid mesh renderer UnityEditor.HostView:OnGUI()

The prefab already has a mesh renderer attached, so I have no idea what Unity is talking about.

Please help!

I am having the same exact problem. The prefab has a mesh rendered attached, but Unity keeps giving me that stupid error! I noticed several people posted about this problem, and it seems nobody is offering a solution.

6 years later and we are still having the same problems XD…I think Unity is too focused on trying to make their lighting comparable to Unreal Engine to give a damn about fixing any of the major bugs…

yes ! i was trying to paint an object as simple as a CONE (!!!) unto a terrain. No Luck because of said ERROR Message … how hard can this be ?
