Known Bugs

1. Drawn lines will start to disappear when drawing alot / holding the marker down on the whiteboard

- This is on purpose, this is to stop the marker from continuously drawing, in-case it is left leaning on the whiteboard. If this is not done an absurd amount of particles will start lagging the scene. A sort of timer ticks down until it starts culling particles. The whole particle system has to be redone using Projected Texture Rendering, instead of spamming out basic sprites. You can avoid this issue by simply releasing pressure on the pen every 10 seconds.

2. Able to draw with the marker facing the wrong way / floating lines

-since the particles don't lock to the whiteboard the way it does in Half Life : Alyx, or The Lab, the particles can occasionally start drawing prematurely. or if your holding the pen upside down, can draw off the board. (to be honest the upside down marker thing is a simple, yet tedious fix that I haven't gotten around to doing.) Again this will be fixed when i redo the system with Projected Texture Rendering.

3. Drawn lines look strange when turning head

- Caused by using basic 2D sprites, will be fixed when I redo the particle system

4. Able to toggle ambient sound with the monitor turned off
