Currently, Weta is an outsider. Even internally, the acquisition had raised eyebrows among the trenches. The decision was criticized quite a bit by game developers using Unity as well. Unity itself is also somewhat troubled direction wise; their biggest product is a game engine, but their biggest revenue source is ads. They merged with an ad company recently, and purchased a movie VFX studio. They seem ready to pivot to whatever tech trend that they can catch.
> With your "Unity... Well.", what did you mean? Weta and and Unity aren't doing this?
I would say that "Epic is deeply invested in building stuff for the movie industry," while Unity isn't. Weta may be established in the movie industry, but the Weta Unity bought is the tool division, not the VFX division. Weta tools is also an acquisition, and does not create waves throughout Unity like how movie production make waves inside Epic. It is the difference between an acquisition to compete, and a vision to expand.
