The way Grass'2'Matic works is by a seperate script. All you have to implant in your game code is 1 line. Then G2M does the rest of the work. When you have done this, you can place an object into your level that generates grass around it according to the settings you give it (see the editor above). I will release a video of it in action shortly.
Looks nice, but I'm not sure sprites are the way to go for realistic grass.. because they will alwys look kind of fake up close, especially when looking at it from above. You should give users the options use their own models i think.
Oblivion, for instance, uses models for grass (they do use sprites for leaves and stuff on trees though).
Looks nice Bright but I wanna know like many other 3DGS users, will this grass be a framerate killer or not I hope not because the grass looks sooooooo amazing !!!!
About the grass and the framerates, depending on the scale of the grass area and the amount, the higher it goes the more droppage of frame rate. The grass does turn off at a certain distance so it will prevent most of the lagging.
I will be releasing this to the public today, tommorow or the day after. (When its done)
