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 lanternleaf item having 3D mesh elements. The lanternleaf, triangleweed, priest's mantle, spoonwheel, paddlewheel and widow's head items come as singular plants, while the dragontail item comes as single stems and bushels. The Widow's head item has a set with and without fruit. Each group has 8 different individual objects, exceptions being the lanternleaf, paddlewheel and priest's mantle items (10). 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 or disconnecting the nodes.
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.
