Resource Packs
Notes
If you get lighting errors on the face of machines after installing a texture pack try setting glow texture to off in gregtech.cfg.
Additionally, it is recommended that you place any GTNH specific texture packs prior to global replacers (such as Faithful). GTNH is in active development, while many older texture packs for 1.7.10 are not. Missing animated textures in particular can be avoided in this way.
The following texture packs have been reported to work - but if you encounter issues be sure to test with the packs disabled.
