is there set of configs to use to enable always rain/snow?

@resinate Honestly I never thought about this. You could try manipulating the rain configuration properties so that the inactive time is 1 (1 tick) and the active time is a really really large number.

EDIT: Oh, and you will probably want to set the rain strength using the /ds command. Otherwise you may be stuck with a rain intensity you don't like, such as too heavy or light.

@resinate Have you had a chance to tweak the settings to see if you can get permanent rain?

Pushed a BETA of v3.5 to CurseForge. Note that the new version has a library dependency on OreLib (another library mod I made). Make sure you read the release notes prior to upgrade.

With v3.5 I am removing rain control I've decided that the feature move too far into affecting game play which is not what I am intending to do with DS.
