Hello everyone.
Here is my way to build a bridge for your scene.
Select few trunks you love.
rescale them and place them where you want.
For me something like that:
Yes it’s a big one, probably Sequoia
Put everything in an empty game object called … bridge ? for example.
In the Parent Game object add an cube and resize it to simulate a kind of floor like this for me:
Bake your NavMeshSurface.
And hide the cube.
Let’s traval the world !!!
You have now your own bridge walkable easily.
Don’t forget to display again your cube when you will recalculate your NavMeshSurface later.
