Anyone managed to find / create a decent tiling grass texture map? Clearly none commercial, it's just Google Images is throwing ones with shading my way, which tile badly.

If you have, wanna send me it! :D

I've got a surface that I use most of the time but it's got commercial textures (although they aren't great).

The textures are seamless but they're still prone to obvious repeating patterns. What I did was use two complete surfaces (colour, diffuse, spec, bump etc.) and use some noise to blend between them which prevents patterns emerging at exactly the same distance apart...obviously 3 or 4 surfaces will work even better. Using the fake grass method (duplicating the geometry and adding a clip map) you can get very convincing grass.

Might give multi-textures a go, I was just been a lazy monkey trying to do it all with one! But hey, that's me, lazy.

Hey Matt

You can give these a try - two I shot myself, then image synth'd and the other is a render from modos fur. See if they are any use to you.

I included the modo scene if you want to play about as well, but I'm more than sure FFX could do the same...just that I have this handy

it's not a problem if the textures are big enough but even the commercial ones are quite small or, at least, only cover a small area.

I really need to update some surfaces, I used to have a preset with the layered grass plus some stripes for freshly mown effects and some daisies, all of which could be enabled or disabled...but I lost it on a corrupted CD a few years back. I made a similar thing for bricks with a layered PSD which has the base colour, mortar colour, varying degrees of weathering and roughness etc...it takes a while to get right but saves a tonne of time in the long run.

Wow, thanks Phil, will give those a try!

I've used the multiple grass image method, works good.

If the images look good tiled at 1mx1m set one up bigger. So 1.3m x 1.3m, then offest it just a bit. Then play with the opacity of the layers.

One image I used was green and yellow, the other was hand drawn green and brown.

No problem, you'll find a lot of useful ones here : http://www.cgtextures.com/

than make them endless in PS and use two of them with a procedural as Alpha to blend them.

Matt have a look at Carms youtube channel , he has a good tut on texture's / grass .

making a tile texture for grass aint that hard with the old photoshop , Videocopilot has a nice tut .

When you blend two textures together use a procedural as an alpha for the top layer. Should break things up real well.

Give Genetica a try. It will take any 2d image and make it tileable. The better the image the better the result.
