In this Blender 2.8 and Godot video I show how to export a 3d model from Blender to Godot as Collada (dae). I got a request on how to export the colliders and how to import them again in Godot.
This is shown in this video: You have to follow a naming convention and add -colonly to the name of the model you export. Then in Godot a collision shpe for this object is generated.
For demonstration I use the Godot project Truck Town that you can download here for free:
