Don't you hate it when a setting is depicting a different planet or a strange fantasy world, yet the plants look like they are coming from the forest nearby? This is part of a larger project: the herbs part will be around ten sets when done, each containing 7 different plant species.
This set contains 7 species of small to middle-sized herbs and bushes, which are composited from sheet elements, with the pagodaplant item having minor 3D mesh elements. The miller stem, ringleaf, pagoda plant and litter umbrella items come as singular plants, while the others come as single branches and small groups of 2-4 branches. Each group has 8 different individual objects, exceptions being the singular axeplant and featherbush items (6) and the litter umbrella item (12). The material setup includes diffuse maps (with the surface texture and colouration being separate), roughness, normals and emission (for the bioluminescence), as well as a translucency effect for the leaves and weedy stems. By having the colour and surface texture separate, it is reasonably easy to either edit the colouration of the plants with RGB curves or give the leaves a different colouration altogether. All plants also have glowing patterns, which can be edited in a similar way to the colours, or removed by setting the emission node to 0.
The native program is Blender, so I can't say if the conversions will work properly in other programs, but it is reasonably easy to use the textures alone, since they are simple composites of stem/branch and leaf textures.
