GRASS-Procedural or Texturemaps

[kbotnen]

I dont know which one is the best, but I use tiled (bitmap) textures for a similar type of scene. I purchased my gras from ambientlight. Nice resolution and fully tilable :) Or you could equip yourself with a digicam and shoot the textures yourself :)

My most successful grass wasn't used for as large a scene as you want to do, just a small lawn. But here's how I did mine, and keep in mind this is a high poly way to do it, perhaps not good for animation. But. First I had a 1200 X 1200 grass map. Not bladed grass, but leaf grass, nore like clover. I used that to make a displaced mesh. (I'm working in Max. I dunno if these things apply to other programs) Then I made a composite map using my grass map as the main texture and another dirt and two more grass maps for variety. aside from the main grass map, the other maps were tiled 3X3. I dislike tiling in even numbers for organic textures. Just doesn't look right to me. I also used a small amount (3) of displacement on the composite maps. That worked quite well for me.

On your project, you don't need long bladed grass. You could probably use a blend map with a good mask to get the mud where you want it. I agree with kbotnan on this one, find a good tileable grass map (no major variations in shading as these will repeat and blow the look. You want a nice even color) You don't need long bladed grass since you're in a baseball stadium which will have well manicured grass. So make a bitmap of your tileable grass and apply it for displacement as well. If you have render displacement. If you use Mental Ray to render control your displacement carefully. MR blows displacement all out of proportion for some reason.

Procedural textures are good for some things, but for natural and organic objects nothing beats a bitmap image applied well. And, as you're doing animation here, you might want to try applying the texture as normal maps and burn em in.

If you have trouble finding a good grass texture, try my website:

Do a search for grass, of browse to Nature->Grass

The tiling is up to you :)
