I absolutely agree with this feature request.
I would love to see a response from someone at Roblox about this feature, especially since the only comprehensive response I can seem to find was from almost a decade ago.
From what I can see, we were sort of just left on how its “a very hard project with many open design questions.” It would be very nice to know if the sentiment around this feature has changed at all in the past decade, especially with the developments on both the rendering engine and the lighting engine.
Not to mention, the post used the potential additon of new post-processing effects as reasoning as to why it wouldn’t be worth it to work on a shader system. Since then, we have gotten a very negligible amount of post-processing effects, and not nearly enough to cover most use cases that would be provided by a shader system.
Kind of feels like the whole idea has been in limbo for 9+ years. If there was another more recent response to the subject I might’ve missed, it’d be nice if someone could let me know via a reply or a DM.
