Hughes Ross has started to work on a PR for this
(https://github.com/minetest/minetest/pull/10140)
but it doesn't look like it will be ready until 5.4 at
least, and we will support pre-5.4 versions for
some time yet. The ability for TP artists to
override special_tiles is necessary to allow things
like flowing liquid textures to be customized in
texture packs.
Add a hack for these, similar to how we did the
inventory/wield image hacks.
Note that we are also forcing overrides for special
tiles, since there may be cases where we reuse a
base image without modifiers but TP artists may
still want an independent override.
Try to detect player traces going through a change in fluid medium
such as water/air or water/glass, and block facial recognition
through it.
Specifically allow air-into-glass transitions, or into any other
medium otherwise clear enough to allow sunlight to propagate.
- Super-clear, ultimate form of clear glass.
- Needs to be molded floating atop lava.
- Not sure about merging this yet; there are kinda a lot of forms
of glass already now...
This makes glassmaking more challenging, as glass that is quenched
when not molded, or left wandering too long, will tend to quench to
crude glass, which is inferior.
This also prevents molten glass from wandering the countryside
forever from failed glassmaking attempts, and precludes keeping
molten glass in "captivity" as a crude infinite light source.
