I'm using prefab instead of objects. I'm able to apply bounds control's handle style (Hololens 2 style) in Objects But not in prefab which I've created. Is there any solutions, How can I apply Hololens2's Handle style in prefab ? enter image description here
You need to save the Configuration in BoundsControl/Visuals as an .asset file for reuse in the prefab. You can also drag the .asset file from Packages/Mixed Reality Toolkit Foundation/SDK/StandardAssets/Profile/BoundsControl/HoloLens2Style_Slate to the Assets folder, modify it to the style you want, and then add it to the BoundsControl component of the prefab.
