Nvidia has announced a major new update to its modding tool RTX Remix. Dubbed RTX Remix Logic, it’s a new system that allows users to set up dynamic graphics effects depending on a player’s actions and position in the modded game. The update will arrive later this month through an update in the Nvidia app.
The new Logic system utilizes 900 of the graphics settings available in RTX Remix to dynamically transform visuals based on in-game events. The feature will be supported in more than 165 classic games. Nvidia has referred to this as a major step in further modding older titles, since requiring the game to respond to real-time game events would usually necessitate access to the game’s source code or engine.
In one of the provided examples, Nvidia notes that players could set up different weather systems in Half-Life 2, making it snow throughout the level. However, RTX Remix makes it so that it snows regardless of whether the player is indoors or outdoors. With the Logic update, players can set up triggers to ensure that this snow doesn’t start falling from the ceiling when the player is exploring a house. The system is set to support more than 30 game events, including things like the player’s camera state, world bounding boxes, the state of any in-game object, the flow of time in the game, and even a key pressed by the player.
“For example, in Half-Life 2 RTX, we can create a door that opens to a multiverse of Ravenholms, each with its own lighting and weather conditions. Each time the door opens, it triggers a new Ravenholm to be rendered,” explained Nvidia.
Along with bringing in better visuals and more dynamic world events, Logic can also be used to create new gameplay systems by making use of multiple game events. Making use of the Half-Life 2 example again, Nvidia showcased a “paranoia” mechanic that adds effects like making the player’s vision blurry to warn them about enemies that might be hiding nearby.
The new Logic features of RTX Remix don’t require programming knowledge to use. Rather, it can be set up and edited through a node-based user interface that doesn’t require the user to write any line of code. This interface can connect to various nodes to set up causes and effects, which can then be tuned to trigger more than 900 graphical changes. The system is also designed to be extensible, which opens up the doors for the RTX Remix community to add their own systems and nodes to the tool, like new game event triggers and actions.
RTX Remix was initially released all the way back in April 2023, and at the time, only supported older PC games that use DirectX 8 or DirectX 9 graphical APIs. Over time, however, Nvidia has slowly expanded the number of games that can be modded through the tool.
