Nope. Galileo was right for the simpler reason that he was right.

Thats the most impressive CG grass ive ever seen! We gotta get results like this using just the fake grass shader

Nice!

Here's one I done a couple months back to get planetary grass coverage just using shaders... I'm no good with functions in T2 for now so, this is all done with PFS's and surface layers. Literaly billion, upon billion of little perlin spikes make the blades of grass, which are stretchable for different lengthed grass types.

The full walkthrough for the .tgd file can be read here... http://stonefingeriiii.googlepages.com/t2grasstutorial although, the method I use now has been somewhat simplified from this write up, with generaly the same effect, I'll post the new method as a .tgd here too but, without a tutorial. It's basicaly the same with some nodes stripped that weren't essential or could be streamlined a bit.

It's very quick to render 'grass' this way.

i am rendering it right now :)
yeah it's real fast to render ;)

it seems that you're always on "searching new tips" mode man ! good job again !

Hey, I rebuilt this file to avoid the clipping lines that seemed to plague it.  Its also a simpler node design, with more control over the shaders via a default shader.  But I did steal Dhaval's terrain and color fractal to keep things comparable.

It renders well at 400x300.  But CRASHES on anything bigger, just like the original.   >:(

Bummer.  Can't wait for that update.

Hey Dhaval, here ya go.  Sorry for the delay.  Was stuck working 12's for nearly a week!

The higher resolutions look alot better.  There are also no clipping lines (as seen in the other file), and I was able to simplify the node design somewhat.  It uses your colors (as I thought they looked great), but otherwise, the nodes are all 100% new.
