I’m glad to see that the DEMO demonstrated at the RTX conference of Nvida was developed using UE4. It seems that UE4 can already support RTX technology. But at present, there are no official tutorials related to it, and the editors we use have no relevant options. So, if I want to use this technology in UE4 game development, how should I learn?
I don’t think this technology is implemented yet. But I’d appreciate that you don’t have to learn much to use the new technology when it’s released. Probably there will be no more reflection captures, or just to limit an area where raytracing will be used. Overall, the work will probably be easier and the transition should be quite intuitive. But these are only my personal assumptions.
Greetings
UE 4.20 doesn’t currently support RTX.
If you want to start using it now, you’ll need to make your own custom version of the engine. I don’t see anything on the roadmap (Trello) for 4.21 to inclusion, so it might be a while before it’s implemented (4.22 maybe?).
If you’re up to the challenge of your own custom version, I would start here: developer.nvidia.com/rtx/raytracing
You can now download the Dev_Rendering branch on the UnrealEngine Git, build the engine and try it out.
