ive tried google, all i get are programming scripts that i cant do anything with.
and i need any plugin cause i dont have any
Well what do you need. You cant just need any plugin for nothing. Do you need to make terrain? Then you should have "blablabla" plugin. Get me? you must need a plugin for a reason. Not to just have it
There are plugins provided with 1.5 stable. If you did the typical install, do the complete install. The ones provided and 1.4s extra ones are really useless though. Ive never found any use for them at all.
