editing grass animations?

[LyRiC]

Hi there,

Dunno if this was asked before (Hope not, I didnt found a similiar thread). Most ppl know, that zooming in on battlemap causes huge lags on lower systems because of the grass animations. So I tried to reduce that lag, without turning the grass completely off (I just need some eye-candy^^).
If you look at the grass for a while, you notice, that it's animated (moving in the wind). I tried to deactivate that animation/movement, but I couldnt find any entry for that in the descr_grass.txt.

You guys have any idea where to find that entry to turn of the grass-"movement" (animation)?

thx in advance
