.Map :: MoHAA Mapping

I used this sites tut on snow. This is what i did i put my little tent thing then put the rain texture on sides and above it from the land to sky then i input the script info (although i dont think this has to do with it) then i saved and went to compile. When i opened mbuilder i clicked build and when on Q3Map stage it said 27% done and -3081hrs to go and was going at an incredible slow pace i didnt think it would ever finish so i canceled it. Could this be something i did wrong to my map(OH I WILL POST WHAT THE DOS PROMPT SAYS WHEN I GET ON LATER) Thanks

I guess you have an immense visdatasize. Try a -fast vis compile.

how do i do that (ive got a large map but only have 2 sniper towers a bunker and a snowy tent in my map) by the way i made some surfaces detailed and it cut it to about 20 some mins but that still sounds long for notin in my map hardly doesnt it?
