Tetra is a wonderful mod about creating modular tools, much like Tinker's Construct; however, Tetra's textures I feel are rather outdated, using assets from before the 1.14 texture update.
!Default Tetra
Using Ron0's shading in Textrapack I fully reshaped, reshaded, and moved all but a few of Tetra's tool and weapon modules. They look better than ever and now fit nearly perfectly into any modern version of your game!
!Modern Tetra
I recommend using this resource pack alongside Textrapack. Make sure to load Modern Tetra above/after Textrapack, otherwise not all weapons and tools will be updated correctly.
This resource pack makes direct use of some binding/wrap/handle textures by Ron0. The vast majority of colors and default binding textures are by Ron0. This is so all modules have a stylistic synergy even though I didn't make some myself.
All usage of Ron0's assets are done with permission.
To do:
Feel free to use this in modpacks as long as Ron's Textrapack allows it.

Modern Tetra module textures. Enhanced shading that tries to match modern MC's tools and weapons.
