I'm happy to share something I've been working on for a while. I created my own personal library of assets that I use in my material projects, and I'm making them available here https://gum.co/forestplants001 . These assets were made using a hybrid workflow of SD and traditional 3D tools, in order to get the best results.

In this Substance Elements collection, you'll find 8 high-quality, hyper-realistic atlases featuring Forest Plants ready to be used in game productions or personal projects. The clean art style of these elements allow them to work in any production from highly realistic to stylized. Pick between three different color states: fresh, dry, and dead.

Packaged into one neat node, you can either export the atlases themselves or pick 'scattering'. This mode lets you input your own background materials or textures, and scatter the elements across the surface. Enable 'masking' or 'color tint' to make the elements show up where you want, with the colors of your choice.
