NVIDIA RTX Remix Gets Path-Traced Particles To Add Stunning Mods To Classic Games

Yesterday, NVIDIA announced a new feature coming to the RTX Remix modding toolkit— fully path-traced, GPU-accelerated particles, first demonstrated running under Portal With RTX, as well as Half-Life 2 RTX in additional documentation. The primary demonstration was uploaded to YouTube using Portal With RTX to showcase spark particles coming off an energy ball, highlighting how the particles could be manipulated by the user. This includes setting custom gravity on the particles, causing them to rise or fall, or making them burst in all directions instead of being a controlled stream.

Sparks aren't the only kinds of GPU particles that you can use with RTX Remix particles, though. As demonstrated with Half-Life 2 RTX, albeit with a more abstract example in the new release notes, an enemy can be slapped with100,000 particles resembling shedding leaves, all of which have realistic physics and shadows.

Many visual effects will be made ...
