re: film industry problem is, there is no hub in the UK where the majority of studios are located. that's quite a difference to the london VFX shops which are mostly based around the same few streets in soho, central london. being an on-site contractor in games would mean moving around all over the country. many studios…
In your case all the stuff is used in same place so it doesn't really matter, since all textures would be loaded anyways. If props are different and used in different locations then you might want to separate them so it can be streamed properly.
