Some time ago I implemented HTMLMesh into my scene and it worked perfectly. Here is the link to the old build - https://babylonpress.org/test/room11/ (turn to the left to see)
Then I commented it and did some changes in the code during last months. Then, after uncommenting it goes weird, meanwhile the pointer changes when you point over a hyperlink
Here is the new build - BabylonPress WORKSHOP
To call the Inspector press Ctrl+Alt+Shift+I
Still wondering what could have caused this
