Wiki Tutorial 1: Lighting Troubleshooting and Tips Guide
This one is still very much a Work-In-Progress as Eric and I work to get some simple troubleshooting and tips up for everyone. We’ve wanted to do this for a long time and have gotten a little bit of a push to make this available for those having issues.
The majority of these will be simple steps with a little bit of explanation for the “why” of it all.
Over the next couple of weeks Eric and I will be updating this regularly as we knock some of these out.
If you see anything missing or something you want covered please let me know and I’ll add it to our list.
