Well. Most of the green grass are were meant for Tristania3D, but the static objects limit scrubbed my masterplan. The world-famous "Too many static objects" error occurred, and I had to start from the very beginning. This is where I decided that the events of Tristania3D should take place in December instead of July, and there should be showing instead of raining. I made most of the grass clumps 2-3 years ago from photos I took, hoping that these sprites might be useful some day. And so they were. They couldn't fit into Tristania3D, but luckily, GZDoom has almost nonexistent limitz, therefore I can happily apply them in Tristania 2.
About the plants and trees, they are photorips. Since all modern games uses modelz instead of sprites, my only option would be the hard rip, but that's way too many work just for some crummy plants. It's much easier to photograph these, and rip'em from there. I live at a nice little village, where we have big open fields, which means, I can happily build my game from them. As for the exotic ones (cactii, palm trees etc.), I have to visit some shops and take pictures there.
Dry grass and winter foliage is not a problem on winter

The main reason why I have so many resources ready is that I'm collecting them almost since 2004, when I started the Tristania3D project
