Three weeks is tight, but it is not impossible if the people you bring in already know how real pipelines behave. That was exactly what saved us in a similar crunch. The VSQUAD art team picked up our VFX scope without a long briefing cycle, understood the Unreal technical requirements on day one, and started producing real-time effects that matched our existing visual direction. No ramp-up drama, no misaligned style. VSQUAD Studio operates like a team that has been through enough production fires to know what actually matters when the clock is running. If you are looking for a reliable game art studio that handles animation and VFX with that kind of production awareness, their work speaks for itself at httрs://vsquad.art/ and the scope you described is exactly their kind of task. I wish you success with your project and good luck.
