Duckstation: Can you put custom shaders like "GDV Mini Ultra Trinitron" ?

[nightocelot]

Hello guys!
Question: Has anyone tried to put "crt-gdv-mini-ultra-trinitron" shader from RetroArch into Duckstation emu?
That shader in my opinion is the best CRT out there.
I have downloaded "crt-gdv-mini-ultra-trinitron.slangp" file and put it into "DuckStation\shaders\reshade\Shaders" folder
then tried to find it from "Post-Processing/Add" menu in Duckstation but it isn't there.
Apparently Duckstation doen't recognize ".slangp" files so I found somewhere on Github a "crt-gdv-mini-ultra-trinitron.glsl" file and it does appear in "Post-Processing/Add" list but fails to work.

Maybe there is a proper way to make it work?

If it fails to work, try using different renderers like Direct3D 11/12. I was using CRT-Guest shaders and one day they suddenly stopped working. I forgot that I switched to OpenGL for recording footage because it just works better with my setup and didn't know that shaders can't be used with that renderer.
