Ah! Those are very simple to fix and to understand.
They mean that the specific shaders aren't installed. I have installed a bunch of shaders, so I couldn't really notice them.
envmap_noskin_bump_colorspec = environmental map, you may find one of these shaders in a mod
standart_shader_bumpparallax_nospec_high_noterraincolor = I think that's mainly(or solely) for buildings
standart_shader_nobump_nospec_noterraincolor = that's for buildings, too
plume_shader = pretty self-explanatory, it's for plumes. Instead, a tex_mul_color or standart_shader_skin_bump_nospec_high should be fine.
The fix is quite simple: Just replace the shaders with ones brf has installed. Here are a couplq of suggestions:
standart_shader_skin_bump_nospec_high = if you have a bump map but not specular map texture
specular_shader_skin_bump_high = if you have both specular and bump map textures and you want a bit of shinyness(it goes very well on the armors of the pack)
tex_mul_color = a good 'all-around' shader, nothing fancy but looks good in game. No shinyness or anything, though
iron_shader = used mainly for weapons(swords and stuff), a bit outdated.
With the first 3 you will do your jobs. For buildings, I don't know much, but try these:
bump_static = if you have only bump map
bumpmap_interior = same as above, but for interiors
tex_mul_color_static = same as the other tex_mul_color
Tell me if there's any more problems!
