Nope not yet :), it’s not forgotten, just on the very long TODO list
It might be tricky to figure out because again Royale works a bit differently than most shaders and does things in a bunch of different passes, then does the curvature at the end.
This is one of the reasons why it can be a bit slower than some other shaders as well as it has a number of passes at the final viewport res.
Basically any issue that I need to fix with Royale takes me maybe 4X as long figure out how to fix as with any other CRT shader because of the complexity of all the multiple passes.
