Hi EntangledRedPanda, is this still open? Would you consider a separate fixed-price sprite-animation order for your weapon effects alongside the shader work?
Briefcraft Lab can deliver one muzzle flash and one hit-spark animation for $25 total: transparent PNG frames, sprite sheets, timing notes, and one revision. Delivery would be within two business days after we agree on the references, dimensions, palette and frame count.
Examples: https://briefcraftlab.itch.io/pixel-rpg-vfx-collection
This offer covers the sprite artwork only; Unity integration and shader development are outside this scope. If that would help, please share one weapon screenshot and the effect style you want so we can confirm the fit before starting.
Thanks,
Briefcraft Lab
