Specio is a PBR Minecraft texturepack that uses the default texture as specular map, leading to strange, yet beautiful visuals.
Requirements
You can use this pack on both Fabric and Forge, however make sure you have those mods installed:
For Fabric:
For Forge
- Optifine
(make sure you have the "Specular Mapping" setting in "Shaders" settings menu set to ON)
Shaders
It's recommended to use a shader alongside the pack since without one it will look just vanilla. The ones that better suit my taste with this pack are Kappa by RRe36, Bliss by Xonk and Noble by Belmu.
Other shaders I can recommend are VXPT by Zombye and Chronos by Jessie, but only for screenshots since they are not meant to be used for gameplay.
