Hello everyone and welcome to my 16 years on YouTube special...of sorts! In this video, I outline how to add dynamic light for the laser of the turrets from Portal, which was inspired by a viewer's comment about how to do this through the game code. I thought it would be way easier to achieve this by using the Hammer editor instead and this is the result! Please let me know what you think and like, comment, share, subscribe and all that jazz, it helps the channel out. Thanks for watching and see you next time!
