Trainings have different rocket textures

While I was doing the trainings, I noticed that th e rocket textures were different. I also see YouTubers with the old KSP rocket textures. How do I get them?

You can find the old textures in the VAB/SPH by slecting the 'Enable advanced mode' ||> button in the upper-left corner of the screen, then one of the categories other than the usual 'function' f(x).   For example 'Filter by Module' then 'Engines'
