so i ahve a bit of a question, not sure if im gonna get the answer i want but here goes anyways...

i have DLed a CaW that is blank and ready for putting down houses and community lots, my question is, how do i place spawners(buttterflies, Insects, etc) around the world or am i stuck placing them on lots?

If you are going to use CAW, you'll be wanting to do more than place spawners. If not now, then in the future. I recommend reading a tutorial, the two I use most are the Absolute Beginners Guide by Nornities and this very extensive one by Kkrank.

If you have any further questions you will probably get an answer faster if you post on the CAW forums on MTS. Those are the experts, this forum is for the NRaas mod suite and not everyone here is a world builder.
