Frustrated with materials required storage

So I been playing around with different marketplace assets and I noticed the average 4K material takes 200MB or more.
This is frustrating because I add a 3-4 props that barely have any impact in the game and that’s another gigabyte required.
This is obviously for an indie/solo project, assuming I release it some day, I can’t afford ending with something that require the same storage that RDR2.

A few questions I’d like to ask you guys:

  • Should I point to 1440p textures instead?
  • Is it safe to just downsize the textures, is there any special technique for it?
  • Any other tip for saving more space?

I’m not considering compression once packaged, not sure what’s the impact, anyways, if it’s not a storage problem it certainly is for RAM/VRAM usage.

Thanks in advance for any input.
