Does anyone know how to make the tornadoes not make a trench/ravine in the ground on 1.6.4 version of the weather mod?

This setup will work on my version right?

My bad, that was for Weather2, the newer version of the Weather mod, can you paste your Tornado configurations in a reply? I can review it and change it accordingly to fit your request.

I can't add the config fire itself so I add to use a link for it (mediafire)

i haven't used 1.6.4 for a long time, but i think it's the same setting in the tornado.cfg

# Tear up blocks from the ground based on conditions defined
B:Storm_Tornado_grabBlocks=false

I want the tornadoes to pick up blocks, but not the main blocks like dirt, grass, stone etc(like the localized one does on the newer version).

# Use a list of blocks instead of grabbing based on calculated strength of block, if true this overrides StrengthGrabbing and RefinedGrabRules
B:Storm_Tornado_GrabCond_List=false

# Grab blocks based on how well a diamond axe can mine the block, so mostly wooden blocks
B:Storm_Tornado_GrabCond_StrengthGrabbing=true

# Enable GrabCond_List to use, add registered block names to list, use commas to separate values
S:Storm_Tornado_GrabList=planks, leaves

# Treat block grab list as a blacklist instead of whitelist
B:Storm_Tornado_GrabListBlacklistMode=false

# Tear up blocks from the ground based on conditions defined
B:Storm_Tornado_grabBlocks=false

# Prevents tearing up of dirt, grass, sand and logs, overrides strength based grabbing
B:Storm_Tornado_RefinedGrabRules=true

There are quite a few different ways you can define what blocks are grabbed, it might take a little experimenting in an SP game to get the right mix, but like i said i haven't played 1.6.4 in a very long time so not sure if these cfg options are available to you.

What does each 4 options do exactly?

Set this to True:
B:Storm_Tornado_GrabCond_List=false

Enter blocks you don't want the tornado to be able to pick up:
S:Storm_Tornado_GrabList=dirt, grass_block, stone, cobblestone

Set this to True (changes the grablist into a blacklist, basically tells the game to NOT pick those blocks up):
B:Storm_Tornado_GrabListBlacklistMode=false

Make sure this is enabled:
B:Storm_Tornado_grabBlocks=false

Set this to True if not already:
B:Storm_Tornado_RefinedGrabRules=true
