Create: Legacy Copper Post Production
Bringing Back Classic Copper to the Post Production Update!
In version 6.0.0, Create developers changed the appearance of copper to match the vanilla style, simultaneously removing the built-in resource pack with classic copper. This pack brings back all the previous copper texture variants that many players have grown accustomed to!

Additional Features
All metal sheets now also have their former, classic textures!

The resource pack is fully compatible with the Create: Enchantment Industry modification!

Known Issues
Z-fighting is observed on the inner surface of fluid tanks at pipe connection points
The measurement gauge needle on steam engines does not move
The shine on the sides of fluid pipes does not smoothly fade out when approaching the block's edges
(In the original legacy copper, the shine on pipe sides gradually faded out when approaching the pipe rim. Due to block model changes, I could not implement this effect in this pack, so the shine simply reaches the very edge.)
Credits
Textures are taken from version 0.5.1 of Create mod.
The work of adapting all textures for version 1.21.1 required significant effort and time.
