First off this is fan art and not official and, thanks for making a game with such cool effects Riot. This was a interesting project to work on. My main reason for making this was to see if I could match the art style of Valorant.
This project was very helpful because it proved difficult to get those smooth edges on all sides of the wall and get everything masked in the right areas. I was also able to get some practice using Houdini for effects with the poison puff particles. Also this was just good practice for stylized vfx.
