Hello friends.........well I am in trouble...........I want to make a realistic looking grass for a project but unable to do that..... I tried a lot but all gone in vain.....After much efforts I got this dull result......... :cry:

I tried uv texturing mapping method.........I also tried by just directly applying the grass texture on to mountain & also tried the planar mapping method.........any help.........this is my first attempt to such kind of texturing............
Well, I want to achieve this kind of result as made by Mr. Matt Mosses during light house lighting challenge........

I'm a Max user, and so not familiar with Maya, so please excuse me if my answers don't apply.
You have a couple of choices,
The first is to make a tileable grass map, making sure there are no obvious repeating patterns. What I do is make a plane in the front viewport, set the render so that the only thing that renders is the plane, then apply the tileable texture to the plane, with bump and all, tile it 2 or 3 times and then render. I make a lot of tileable and blended texture maps this way. This does a couple of things. It lets you see if the patterns repeat, and lets you create a larger texture. I generally render about 2000x2000. Once rendered and saved as an image, it also lets you go into Photoshop and modify the maps to clean it up and all. Then you can use this texture, without so much tiling, and using the bump map as a displacement map, apply displacement to the ground so as to get the unevenness and height and all. It works. It's not the best way to do it, but it works.

To take it further. Texture your ground with the previously mentioned maps. Then, on top of that, use whatever Maya has for fur and hair to make actual grass. It's expensive as far as render time, but it usually comes out quite nicely.

I generally texture the ground with a blend map of grass and dirt, and then make that map into a displacement map, sort of. But it's actually a dispersal map, height map. If Maya fur and hair lets you use this kind of black and white map to control grass height and dispersal and such, you get something better than just an even coverage of grass. As long as you texture the actual grass well, it generally looks quite realistic.

Thanks a lot..... I got the basic idea & I will try out this in maya...............thanks a lot.
