Terrain not generating tree colliders

Questions & Answers
1

So, I painted some trees onto my terrain, and I can walk through them! Why? The “Create Tree Colliders” box is checked, but nothing’s happening?
Let me clarify: I’ve created a prefab. I’ve dragged the tree I want onto the map, and then I put a mesh collider on it. THEN, i turned THAT into a prefab. It doesn’t work.

I have finally fixed the issue: I put a capsule collider onto a tree and edited its width. It works.

if you have more than ~65,000 trees, colliders will not be created. Also make sure that your tree prefab have colliders attached to them otherwise you are painting trees without colliders!

That’s messed up. The terrain painter should be creating colliders since it can randomly vary the size. And for the life of me I can’t find any prefabs corresponding to the trees I’m using in the assets folders…

Add a mesh collider in your prefab ! (The same mesh than the MeshRenderer
)
