I mean, who should I ask *about*? Who did not get the shirt?
I could! Who should I ask about (name, email or whatever)?
It surely is possible, but someone has to write a tool that does the conversion :) From the top of my head, I'm not aware of any existing tool like that.
Hmm, I thought we have removed all the "atten * 2" stuff from built-in shaders in Unity 5. Which particle shaders that do lighting still have it?
I think some others (that aren't lit) might do "color * 2" as a cheap way of allowing "overbrightenning" effect, where 50% gray color is neutral, and brighter than that allows for brighter particles than the actual texture. If you want to copy them and remove that to suit your needs -- sure, just do it.
I have no idea, nor whether anyone ever said that it's in the works. Sorry!
I actually don't know! Haven't done any Vulkan code myself.
I don't actually know (that's up to marketing), but I think all your mentioned releases were shipped during some big industry event (e.g. GDC) and the trailers served as event material too. Not sure if 2017.1 is going to be shipped at some big event; probably not.
Scriptable render loops have been there since Unity 5.6 actually, under UnityEngine.Experimental.Rendering namespace (and them being experimental; the API kept on changing quite a lot though).
I'm not sure if in current 2017.1 beta they are out of experimental namespace yet (I kinda stopped doing graphics a while ago). I'm pretty sure there is more APIs & stuff to build scriptable render loops compared to 5.6 though.
Probably best to ask on the beta mailing list (if you're there), or in the beta section on the forums.
"Visual Scripting" is put under "research phase" in the roadmap (
https://unity3d.com/unity/roadmap), so definitely not in 2017.1 yet.
