It needs a shader file to make it visible on both sides.
This is from a tutorial here, on jkhub
The shaders i'm checking all use "cull twosided" instead of disable, so i guess try that.
Should be something like
models/players/Swtorguy/swtorguytexture
{
q3map_nolightmap (no idea what that does)
cull twosided
{
map models/players/Swtorguy/swtorguytexture
blendFunc GL_ONE GL_ZERO
rgbGen lightingDiffuse
}
}
I'm an idiot, so, who knows.
