Will the Metal implementation include Shadows from Lights that has been one of the most voted for features for a looooooooong time. I'm getting a little impatient for it.
As for FX plug support, I see two or three users who want it, and FinalCut users are very thin on the ground these days. I don't even remember seeing a job advert requesting a FC editor in the last few years. If you were to implement a cross platform output: making Adobe plugs would make much more commercial sense IMHO.
I assume you'll update to the newest NDI at some point soon too.
Thanks for all your work to date.
From what I have read the url for the .mtl is encoded into the .obj so you'd have to parse and replace that url when reloading the obj. if possible.
Otherwise could you just use an image texture instead of the .mtl in the first instance?
