Hello. To get the reflection shown above, turn on the reflective floor feature on in the player settings. It is the last feature on the list. Please note that this will only be visible in the V2 player once enabled.
As for the buttons, there is no simple way of doing this through the preset editor options but it can be done by adding code to the configurators script. Add this line "api.player.hideTool(toolName)" and set the toolname to whatever feature you want hidden, i.e api.player.hideTool(pan) will hide the pan option.
Hope this helps!
