Transparency within 3D models doesn't render

[Greenwood72]

Alex,

I noticed that vkQuake doesn't render transparency within 3D models. Areas meant to be transparent are filled in black. Oddly enough, regular Quakespasm renders this fine. Again this is just transparency within 3D models, not regular geometry textures. Either than that, your port is performing well!

Can you give an example where this happens? GPU? Driver? OS?

Sure! If you install Redfield's map,The Deepness Below, you will see black boxes around the seaweed. In regular Quakespasm this does not exist. https://www.quaddicted.com/reviews/deepness.html

Coincidentally, Redfield made some custom animated 3D sails for the ghost ship in my entry to the upcoming Halloween Jam (see attached). The tears do not render correctly in vkQuake (Quakespasm was used for the screenshot).

I noticed this too. With the latest nvidia drivers on Win10 with a gtx1080 it does this. Any model that uses palette colour 255 for transparency just shows as opaque black.

On the slightly older AMD RX 480 card the entire model actually goes mostly invisible and jittery with graphical glitches. The sails in your new Halloween map are literally mostly invisible.
