is there a way to tell if an engine supports texture shader?

[necros]

i suppose i'm just missing something obvious.

basically, i want to detect if the engine running a progs.dat has support for the q3 style shaders (via .shader files).
i think only DP can do this anyway, so a way to detect if the engine is specifically darkplaces would work too.

is this possible? i looked through the extensions but i saw nothing concerning shaders. or did i miss it?

[leileilol]

there's no qc extension for q3 .shader support, besides I can only think of five engines that support Q3 shader syntaxes

Darkplaces (2 stages only iirc)
FTEQW
eQuake (p0x mac-only engine, i don't remember if it really is q3 syntaxes or its own script knockoff)
qER (late 2000 version, did it ever release? Anyway it had a conspicuously early q3 shader code in January 2000.......... hmm......)
The suspiciously GPL-violating q1 engine that ships with CIA Operative Solo Missions, supports Q3 shader syntaxes........

ok, well, thanks for confirming that.
what i've been doing so far is just testing for DP_ENT_TRAILEFFECTNUM which, afaik, only DP supports. of course, if anyone adds that in, but not external textures, it'll cause problems. :\

noone else advertises DP_ENT_TRAILEFFECTNUM because its basically flawed for public servers, even if they do support the builtins...
so feel free to check FTE_GFX_QUAKE3SHADERS too.

thanks for letting me know about FTE_GFX_QUAKE3SHADERS. didn't know about that.
