In my mygeeto map i had got snow to work, but now it wont work. Is it because of i removed lowres terrain texture and terrain bump texture?

Why don't you try "moving" the lowres terrain and terrain bump textures back in to see if it makes a difference. If that does not solve the problem, did you mess with your map's .fx file or .req file at all?

well i moved the terrain bump and lowres back in and still no snow. I dont think i messed with the req or fx since then.

Trying cleaning everything and then munging again. If that doen't work, then I don't know what else will (based on the information you provided).

I found the problem, somehow the envsf line in the req had a --. this topic can be locked or solved ot whatever you call it.

So it was a problem with the .req file. It figures.
