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 a part of a larger project: the herbs part is now done at 10 sets, each containing 7 different plant species.
This set contains 7 species of middle-sized, partially flowering or fruiting herbs, which are composited from sheet elements. The wingleaf, reticulated wingleaf, curled wingleaf, millweed and scrawlerleaf items has a set with and without fruit. Each group has 8 different individual objects, being singular fronds, plants made from the fronds and the same plant models with added fruit and flower stems for the listed species. 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.
