Most of the general machines will be Linux workstations but none of them are doing video editing on Linux. They’ll have Mac’s for their in house editors and concept artists.

Windows isn’t common for VFX studios outside of unreal engine use or very specific software.

I would vouch it depends on which country those studios are located, and VFX reference platform exists for a reason.

huh I thought Maya + Windows was pretty stereotypical

Maya + Linux is the de facto for VFX work. Windows with Maya is usually only used in smaller studios or studios that are still dependent on 3DS Max.

ah that makes sense
