Sophisticated Backpacks

Sophisticated backpacks is yet another backpack mod this time with backpack you can place in world, color in different color combinations, upgrade with more inventory and enhance with many functional upgrades.

Backpack in its item form

Can be accessed using a key press (by default B)
Renders on player when put in their chest slot
Curios compatibility makes it possible to wear and render the backpack when put in “Back” slot

Backpack can also be placed in world

Shift right clicking the backpack on the ground puts it down
When in world player can use it the same way they would use a chest
Backpacks can also have items piped in/out using hoppers or any kind of modded pipes, external storage access, …
Shift right clicking the backpack on the ground with empty hand picks it back up or it can also be brokend and picked up as any other item

Backpacks can be upgraded

5 tiers - leather, iron, gold, diamond, netherite
Each of the tiers adds more storage slots and more upgrade slots

Loot / Mob Spawning

Occasionally backpacks and some upgrades can be found in loot chests
And even though rare, mobs can also spawn with backpacks on them sometimes with a bit of loot in those and sometimes they would even play a tune

Configuration

There is a lot of things you can change through mod's config

Number of inventory and upgrade slots of each backpack tier
Number of filter slots in many of the upgrades
Range, speed and some additional features of different upgrades
And if an backpack/upgrade doesn't fit a theme of your modpack you can disable them in the config to disable recipes and hide them from creative menu / jei

Dyeing the backpack in crafting table

Backpacks can be combined with dyes to get them in many different color combinations.

Color of multiple dyes in recipe gets combined similar to how it works for coloring leather armor except backpack can have two colors - main and accent
Dyes to the left of the backpack in the recipe apply to the main color
Dyes to the right apply to the accent color of the backpack
Dyes in the same column apply to both
And once dyed you can continue adding dyes which combine with the current main color, accent color or both
So yes there are many color combinations
Color of already dyed backpack can be washed away by clicking it on cauldron with water

Feeding upgrade

Immune to Explosions (both as an item and block)
Immune to any kind of prickly thing like cactus

When it falls in lava will float up above it and stay there
Same happens when it falls in void except it stays just above the lowest build limit

Portable furnace in backpack which can also work automatically

Regular upgrade works just as furnace would
Auto smelting one will automatically pull fuel, items to smelt and will automatically push smelted items back into backpack

Integration with crafting tweaks and mouse tweaks
Also has performance enhancements that make it faster in crafting than vanilla workbench

To move as much as possible you can use Ctrl Shift Click

Advanced one has filters which allow to filter what gets swapped
In addition to that advanced one enables a key (which needs to be configured in controls) which when pressed will swap in tool into player's hand based on block/entity they are looking at
This is meant primarily for tools that are right clicked like wrenches from many different mods
