In my Terragen store, in addition to presets and scenes, you can also find small objects such as plants, herbs, leaves and even rocks to enhance your creations and make them even more realistic.
All these resources are optimized to be used on all computers. The textures are generally in 2K (2048×2048) which is largely sufficient for this type of resources. For each texture, bump maps are provided.
Here are some examples and links:
