load a .OBJ as a collision mesh?

Question

What I Know:
It is possible to load a collision mesh with open-collada (flags: -col / -colonly)

My Question(s):
Is it possible to load a OBJ or MSH file as a collision shape?
Can not find this option in the editor.
Is it possible to load it by GD-Script?

I'm also interested in how collision meshes work in Godot.
I opened the "3d/sat_test" demo but apparently collision meshes are already included in the scene, no particular file for them but "shapes.dae". There is no doc about this yet on the website unfortunately...

No, it isn't possible (import it as a coll. shape). You have to import your object as a 3D Scene. OBJ files use 3D Mesh option.

Can not find this option in the editor.

But you can convert it manually! Import your OBJ model/models as a 3D Mesh, create MeshInstance node, load imported .msh file, click on Mesh button (in the bar under tabs next to the View button) and choose Create Trimesh/Convex Static Body. Done.

Is it possible to load it by GD-Script?

I don't think so.

Node CollisionShape needs a Shape, which is a Resource data type. Resources can be saved to files or built-in (packed in the scene). And they are documented right here. http://docs.godotengine.org/en/latest/tutorials/step_by_step/resources.html

Thank you for your answer!
That is what i have searched for.
The menu-botton is hidden in the 3D-Viewport header tabs.
I have not seen it, of course it´s only showing up when the
Mesh-Instance is selected in the Scene-Tab.
The 3D-Viewport is not a place where anybody would search intentonaly.
However, it is good to know where i can find it.
