lostclimate, soft shadows are possible with a shader, like matt said sphere does it, it's not impossible, everything is possible, you just need to know how to implement it and have the right hardware to run it, however, at the guy needing help, check the wiki, the link is at the top of the page, if that doesn't help, click matt's sig, from what you say it seems you haven't looked enough, if you can't find anything in the forum, check the link or downloads page, they are accessible at the top of the page, if you still can't find anything, wiki is the place to be, and if you still can't find anything, if you have searched and searched, then post your problem, don't post it as soon as you have an error, try to find a solution first.

edit: i do not mean this post as offesive, i'm trying to help, you need to listen when someone tells you how you can fix it, if i have to post a direct link to what i'm talking about i will....
