I guess there may be a compatibility issue between SteamVR and this plugin after the SteamVR update.
When I start Chara Studio Whith SteamVR(The startup parameter is charastudio.exe --vr), the handle cant load in game ,the menu interface "lying down the ground". Then I try Start with "charastudio.exe --vr" cmd, the handle will load ,but the cursor cant click button in menu interface. So I open SteamVR Desktop , I find there's 2 cursor in game. One is the VR's cursor , the other is vanilla's, I move handle the VR's cursor cant follow the handle's ray, And only when I use SteamVR Desktop the VR's cursor can click the button, but When I came back game it cant click button again.
