Under 4KB Challenge

Completed Unranked Jam for Data Packs, Maps, Mob Skins, Mods, Skins and Texture Packs

26

Have your packs been getting bigger than you wanted? Like mine have even gone up to 1.2GB! Can you do less then 4KB?

About

Have you ever created something in minecraft? And when you did how big was it? Well if it was over 4KB then it would be no good for this jam.. Can you create something that's under 4KB, while still being functional and not just slop content? Well lets see!

  Some "people" have been questioning if the jam is even possible. To them I say- If the jam was impossible do you think I would go through all the hard work of creating the icon & banner let alone publish the jam? But I guess it would not hurt to give proof.

  Why did you put people in quotations
  
  ScotsMiser Oh, under 4k is eminently doable… but severly limits the pack.png (and probably kills the ability to use overlays)

  Also find it funny as I've checked multiple of the people who complained and one of them had a 1.13 KB pack..

  I have a question... I want to upload a bee skin, but I'm not sure if I can upload it. The file size is less than 2KB (1.504 bytes), but the size on disk is more than 4KB (4.096 bytes). Can I upload my bee skin?

  Formally you need to hear back from @Rocraften [ping won't work ¯\_(ツ)_/¯ ], but I would think the 1.47Kb file size shouid be fine.
  
  The 4Kb size on disk is likely due to a single sector of your disk (the smallest organizational unit the disk recognizes) is 4Kb.
  [Sector is old nomenclature, this may also be refered to as cluster or allocation unit.]
  
  Rocraften That's a bit tricky, I would try compressing it or uploading the skin to an online converter to see the actual main file...

  But I can't adjust the size on disk. The size on disk is still over 4KB; https://imgur.com/hnAS7n0
  
  I have uploaded the skin on PMC (The skin has the original size of 1.47 KB): https://www.planetminecraft.com/mob-skin/orange-traffic-cone-bee/
