Hello, I seem to be encountering the same issue. It appears that the model is only a mesh instance, so we may need to set up collisions manually. If you have found a solution to this, I’d really appreciate it if you could share it with me :)
Hey, I have been getting some collisions to work by editing the names of the objects in blender, and just adding -col at the end. It worked so far with the house, but I haven't around with it too much for everything else.
