Since Roblox doesn’t support any shader language for any rendering API, how can I use Luau to instruct the GPU on how to render stuff?
You don’t. Roblox has no lua API to interface with the GPU.
Some people have pulled off raytracing, but these raytracing qualities are not that perfect. I believe some features are not introduced until the backwards compatibility suffices to not forward a significant impact on older games.
Yes, it sounds like a heavy operation and not a good fit for high level coding languages, but I would like to know how it can be done(e.g. raytracing)?
I remember spotting some creations in #waywoc some weeks ago or maybe months. Perhaps you can look for those people who have been testing that?
