Hi,
one of the things i drool onto in forums like Evermotion and so, is how vegetation and grass are threated.
So i elaborated my old "wafer" trick and i added some layers of instances on it, btw in Kray. Result is not bad and timings too (6 min on a I7 960), so i hope it can encourage some LWers in trying a better grass.
(btw not *that* grass.... but i suppose that speaking of this without being asked could raise questions, so lets move on).

Neato!!!

This is your trick with polyplanes and clipmaps?

yes, at least for short grass. Then flowers, clovers and high grass are instanced. Covering a whole field with instances has too high rendertimes, and again instances have issues at borders (usually you instance a circular patch of grass and this is not a friend of straight borders). This way you can cover easily with a base grass ever yarea, then you add secondary instanced layers only where possible and needed.

This really cries out for a video tutorial. (I read the previous thread, but it evolved as it went along and is now many pages long) :)

i'll try to find some time for the video tut. Any suggestion to record video (better a free app ) ?

It would be great to see it too.
What I do these days for grass is an image map photo and then two or three procedurals on top of that at different opacities to break up the flow and to give it some form of mossy grass feel.

Nice... and would love a tut as soon as you have time. Just a side note, your turbosquid stuff sig link doesn't seem to go anywhere?

thanks, it was a dead link indeed, i deleted that stuff since it was starting to get too old.
About tutorial... too busy, but basically it just relies on wafer-trick for base grass (time ago i made an extensive thread about this, called "interesting technique") and Kray's instances for all taller grasses... nothing too complex, just an example of what one can get with a little effort ;)
