I have been seeing a lot of questions about the Foundry and answering quite a few as well as other authors. Please check out the Youtube Tutorials provided by the STO site and most of your questions will be answered as well as the understanding of the issues which is better than secondhand answers from us.
Don't get me wrong, I don't mind helping, but I spent 2 weeks watching and rewatching the tutorials and it has
helped me grasp the basics easily as well as learning the more advanced features available.
Also, visit Starbaseugc.com and sign up and a lot of other help and information will be available to you as well. Kirkfat from starbaseugc and The Preacher are featured in most of the video tutorials you can access thru the STO site as well as the others and they are extremely helpful in making it seem easy.
I hope this helps and with the additional help from the experienced authors, you will get a good grasp of the awesome abilities the Foundry offers.
