What the title says. It's supposed to control the size of specular highlights, but doesn't seem to be working as a launcher tag. Is there anything in the new shaders that overrides launcher settings or something? I can't tell a difference when I choose drastically different values for spec_exp.

First image is spec_exp 1, second is spec_exp 16. I couldn't get the two screenshots taken with the ship in the exact same spot, but I think it's still pretty clear that there isn't much difference between 1 and 16.

my guess is the shaders are ignoring it.

i think what your looking for is -ogl-spec -spec-exp seems to be deprecated to the old nonhtl code iirc

seems to be deprecated

If so, this should be documented in the wiki. While at it, it'd probably be smart to double check for any other deprecated lighting flags.

There's a lot of things that need to be documented in the Wiki.... the SCP Sexps page alone is missing a crapton of stuff...

Incorrect, it's used in void light_apply_specular in lighting.cpp.

It might be related only to Fixed Render rather than GLSL Shader pass, true. But it is not deprecated in the engine.

Secondly, -spec_exp values will NOT show themselves at ALL in the F3 Lab. The LAB is not lit by a sun, so it will do absolutely nothing in changing those values.
