Hello @RonnyDance, In my first GX for the HQ Photographic Textures Grass Pack Vol.1, yes you will have already pre-defined and ready to use Grass Details on Scales for example like that: You can yet, Edit each grass at every moments if you are not satisfied within' and customise on your own way. So you will have all the Grass compiled in only one Resource and in 2 SubCategories of Spawners like that: Everything have been pre-settled but you will be able to modify each tweaks on the visualiser or directly on the Resource to you to get your results intented if so: And about the Spawners, yes you will have some Perlins or not like that: Everything is flexible, you will be able to delete some grass or replace them, tweak the Spawners etc. I post again what i wrote on my forum for more informations: http://forum.unity3d.com/threads/turboscalpeurs-grass-forum.395638/page-2 #53 Reply "So, i'm near to make the Update for the HQ Photographic Textures Grass Pack Vol.1 v.1.7 with its GX eXtension for Gaia; Thanks a lot of to @AdamGoodrich , @Shawn67 and @jimmikaelkael for all the helps & testings A small Description: The HQ Photographic Textures Grass Pack Vol.1's GX eXtension for Gaia, will give you the abilities to use fastly some Pre-Settled Grass Environments or to customise very easily all the Grass compiled in the Pack in Gaia/Unity 5; You will just have to click on the "Create Pack Resources File" Button and then add each Spawners you want to use; The Spawners are categorised in 2 Sections: Spawners: These 16 Spawners are compiling all the current 72 Grass Textures from the HQ Photographic Textures Grass Pack Vol.1 in subcategories; they are basically pre-settled in order to you to use and mix them on your own wishes. Spawner Combos: These 7 Spawners are Pre-Settled in All-In-One Flora's Areas to give you still more quickly some ready to use/play Grass Environments. NOTE: The Spawner Combos are very dense and can affect your Framerates as well if you don't have an High End PC Machine; if you expect some low FPS, don't forget that you can at every time settle each Spawner in order to have less density/Grass and win of Performances. I will make some Videos Tutorials/Demonstrations soon to show you how to use the GX eXtension and mostly seeing the widest possibilities you have within'."
