RTX Reactor is an experimental project from Vanilla RTX's developer, its job is to allow you to use your any of your favorite Bedrock Edition texture packs with ray tracing. It does so by generating full RTX support for them.
All you need to do is to give it a regular Minecraft texture pack! RTX Reactor processes it locally and outputs the fully ray tracing-capable version.

The overall vision for RTX Reactor is to have it generate packs that would be usually better or no different than when the average resource pack author tries to add ray tracing support to their texture packs (which in reality most never do, there are very few original non-vanilla texture packs for ray tracing floating around the internet)

RTX Reactor will eliminate lots of manual human effort, so that players are no longer limited to Vanilla RTX or a few Minecraft RTX capable resource packs, but instead thousands.

For the time being, my Ko-Fi page and Discord serve as the home of its development news.

RTX Reactor is a work-in-progress, but if you wish to get access to current closed alphas and support its development, consider becoming an Insider on Ko-Fi. 

2026 Update:
RTX Reactor is coming to the Vanilla RTX App later this year.
