Physics issue with Unity scaling

Hey, so I'm trying to get my already existing project onto the HoloLens. For this I'm using the HoloToolkit Unity package. My problem is that the existing things are heavily physics based. And when I export it to Hololens as-is, then they are by far too big. However if I scale everything down by a factor of 10, the physics engine is completely messed up, freezing up my pc so I get below 1 fps.

So my question is, is there a way to increase the generated room scale, so I can keep my objects at the same size?


  • Maybe you could scale your model down to the size you want in something like Blender and then reimport it into Unity at a smaller size but with a scale of 1,1,1 or whatever scale you need?

  • I tried doing that now, but that didn't fix anything sadly. I would rather scale the camera up in some way, so the objects appear smaller. But for that I would also need to scale up the mapped room, and I'm not sure how to do that.

  • There is an article on the Unity blog that discusses solutions to this issue: https://blogs.unity3d.com/2017/11/16/dealing-with-scale-in-ar/

  • @gene this is good stuff. I haven't seen anything that talks about this issue before. Definitely would have saved me some time if I would have saw this.
