I posted this because I was reading the information in Building Multi-User ML2 applications with Photon Fusion and as I was going through it, it was not working as written. The last explanation in the following section says that after marker recognition, the controller's bumper can grab the cube, but the cube cannot be grabbed. > **[Photon Fusion | MagicLeap Developer Documentation](https://developer-docs.magicleap.cloud/docs/guides/third-party/networking/photon-fusion/#part-2-run-the-marker-colocation-scene)** > > Guide on using the ML2 Photon Fusion example project Is there a problem with not being able to grab cube?

I haven't read all the way to the end yet, but at this point I am not sure because the instructions for operation are suddenly there. > **[Photon Fusion | MagicLeap Developer Documentation](https://developer-docs.magicleap.cloud/docs/guides/third-party/networking/photon-fusion/#running-marker-colocation-on-desktop)** > > Guide on using the ML2 Photon Fusion example project **Unity Editor version** : 2022.3.11f1 **ML2 OS version** :1.4.0-dev2 **MLSDK version** :1.4.0-dev2 (Unity Package 1.11.0) **Host OS** : (Windows/MacOS) Windows **Photon Fusion** : Fusion SDK 1.1.8 F Build 725 ---

Magic Leap, am I correct in assuming that you will not answer this? ---

Hi @tokufxug, the sample only supports short range interactions so you need to place your controller into the object to grab it. However, that is good feedback and we will look into making the objects grabbable from a distance. ---
