If you don't use Courier's Cache (very large scaled crates), or for performance, the 2K version is fine and still looks great

4K diffuse, 2K everything else

This is just a hotfix to 1.0 for the open crates (tubCrates*.nif) meshes included with either version of the mod.
I accidentally left experimental parallax enabled but didn't notice because CC was overwriting my mod. Install after or over 1.0
