Great render, this new grass technique is working.

It would be good to see the raw render and also how it would look if you just rendered using a standard grass texture.

Thanks for sharing.

regards,
Nat

here is the raw render. (brightened a little)
I'll grab a grass texture from the browser and run another render.
will upload it later

using the same texture, rescaled and reoriented. works for birds eye views too.
scale is 1:1 ratio rather than the 3:1 and the array is not necessary.

Thanks Andrew, great to see the comparison, its a big improvement on just using a normal grass texture.

The birds eye view is great too, it would be good to see a SketchUp screen shot of the birds eye view with hidden geometry turned on.

Your have definitely got a great solution to 3D looking grass!

regards,
Nat

Thanks.
There is no array for the bird's eye image. From this POV I was able to apply the texture to the ground plane in one shot. At any distance closer perhaps I'd have to divide it up like the ground level view. The only thing I did do was rotate the texture so it was appropriately oriented to the POV. 

I guess what we can take from this exercise is that we can use the same texture, and from a modest elevation it is even easier to execute than the ground level view.

Also:
This model has two scenes. I duplicated the ground plane and set each on a different layer. I duplicated the grass texture so that I could modify each independently and then apply to the respective ground plane. My scenes are set to have the correct ground plane on for the corresponding POV.

Both images were cut from the same model, starting from the same grass texture. It continues from here...

I agree. Thank you for sharing your technique. Very generous. I have an exterior render that's coming up soon. I might give it a try.

the little patches of white flowers are 3D?

No. None of the ground plane is 3D.
The grass is a texture and the flowers are brushed in in photoshop.

Any tips for an amateur photoshop for making the patches of flowers?

tips... sure. two things-
1. you have the have the right tool
2. how you apply the tool is entirely up to you. beauty is in the eye of the beholder. 

With that being said, I can assist you with the mechanics of item 1, setting up the brushes.

here is what I do,

search the internet for photoshop flower brushes. you're looking for the ABR file. when you find a set you like, place the ABR file in the folder where the other photoshop brushes reside, or pick a couple of colors, select the brush icon, then the brush pull down menu.

select load brushes, and find your downloaded ABR file.

pick a brush, this one looks good.

lets paint some flowers!
give it a swipe. not very exciting. click the brush palette menu. located here on a mac. not sure if it is the same for PC's
Picture 5.png 

I like to add a little scaling and angle jitter. give it another swipe.
Picture 6.png 

Add some scatter, give it a swipe. This (the swipe) doesn't have anything to do with the setup but it does give you a chance to see the affect of the changes as you select them. makes it a little easier when adjusting the settings.

I like to include color dynamics, mainly jitter between the foreground  and backround colors. test it out.

I also like to use the airbrush option, which adds the ability to fluctuate the spray.

after that, the rest is up to you...
good luck.

I would have added this to the T,T&T section because I found it really interesting!

Andrew would have to copy the post and create a new thread.

I could do it, but I would be taking credit for it (it would appear under my name), and I'm not going to do that!

It would be a great new topic in that forum though!

No problem.
I'll copy it over.
Bigstick,
Just the flowers, or the grass technique too... the descriptions from the other two threads?
Whatever you want.
Let me know.
