If I'm not wrong, the grass was done with Sasquatch's wind.

How mauch time did it take to render all that grass in all those frames?

I see now that the branches do move a bit but not enough.

There is no secret about the moving of the grass. with sasquatch is quite easy doing it. It's prepared to do it.
Kvaalen - Not much time.
I've a P4 1,5 Ghz with 256MB and it took about 1,5 min each frame.
For what I can see Sasquatch is quicker then Saslite, I don't know why. It should be the other way around, don't you think?

From what I noticed, Saslite has many limitations other than having less options, and a slow render might be one of them. :p

I have never tried Sas before, but I do have one question. The different colorations of the grass... it this being "picked up" by a color map applied to you "hill" object or is the color a function of your settings in Sas?

In Saslite you define one color, but in Sasquatch you define 4 colors. You can also use procedurals and image maps.

AHHH so many sunset pics!!! :D :D :D This looks good. Anyway we could get an animation of possibly the tree swaying in the wind and the grass like that also?

There already is an animation on the first post, and it's worth watching too.
