Solstheim v.1.1 released
* a much more varied flora, 20 different plants/grasses covers the grassy areas and, sparesly, some of the snowy areas (only in Lush version).
* 2 versions of the grass included; Lush and Sparse.
* Grass no longer covers the dirt textures (in forts and on roads etc).
* Grass is now random in sizes to make it look more natural and diverse.
Dude, leave Solstheim alone! Its mint! It'll drive me nuts cause I won't be able to choose from your 5+ updates, bet they'll all look stunning. I could have never imagine grass to look good on Solstheim but you really did it! I'm starting to think I need to mod Oblivion to keep up with Morrowind because of you!
The Ashlands on the other hand need a little more work, It'd like to see a more brownish/grey grass and maybe mixed with the current ones, kinda like what you did with Solstheim. Also the grass should be shorter there, like it normally is in very dry / hot areas, otherwise it looks like a fresh prairie which it is def. not.
Look at some pictures of the Idaho lava field online for inspiration. Thats kinda how I imagine the Ashlands in real life.
