Not only are they obvious derivatives, but you're openly lying about it. That contradicts the 'attribution' portion of the license as well; not only are you not allowed to make derivative works, you're required to attribute my work to me. That would be true even in your bizarro-world interpretation of the license.
So respectful.
I think at this point the only thing to be done is a line-item demonstration of where Mira is taking art from. Then moderation can decide - since Mira thinks she's above listening to polite requests or playing nice with the rest of the forum.
I don't have a ton of time to do that right now, but I can start us off with a list of the artwork I can definitely tell is bashed from my sprites:
"sw_annihilator_hardpoint" and "sw_annihilator_turret"
"sw_fusion_beam_hardpoint" and "sw_fusion_beam_turret"
"sw_gauss_hturret" and "sw_gauss_turret"
"sw_hyperpulse_hardpoint" and "sw_hyperpulse_turret"
"sw_lightning_storm_hardpoint" and "sw_lightning_storm_turret"
"sw_lightspear_hardpoint" and "sw_lightspear_turret"
"sw_phalanx"
"sw_plasmastorm"
"sw_tesla_coil_hardpoint" and "sw_tesla_coil_turret"
The textures "annihilator_core" and "ring_trail" use the ring texture from "magellan_projectile_contrail_ring" without permission - anyone can draw 'a ring', but matching the exact dimensions of mine is a tell.
"doublehelix_trail" is actually a texture (SRD_helix_beam) I gave Nia for the Sylphon mod; up to Nia if that's a problem, but it's used there and in the (very ugly) "devastator_beamcore" texture. UPDATE: not an issue as Nia's fine with it.
I have additional suspicions about:
"gaussrail_slug"
"sw_devastator_hardpoint" and "sw_devastator_turret"
"sw_novax_hardpoint" and "sw_novax_turret"
but would appreciate a little help IDing the precise origins of some parts.
Other modders, please feel free to chime in about your own artwork.
What's really funny to me is that my art isn't a great fit for Starsector; it's as much an idle exercise in making vector artwork do stupid tricks as anything else. There's so much more fitting stuff out there to steal from, if you're gonna.
