I made a sci-fi container, one version with an inside and one without.

Textures are coming in 2 different resolutions (2k top part, 4k main part - or - 1k top part and 2k main part)

There is one version of the texture with dirty colors (dirty colors are hand painted in blender, rest is from own photos and CC0 textures from this site). All these different "versions" are shown in the third preview image.

Also included is a high-poly source mesh.
