Help with creating a map please!

I’m new to Garry’s Mod as you can see. I need help with creating a map though. My problem is that, I downloaded Source SDK and stuff and it lets me use HL2 and 2009 as my engine. I try to make maps on hammer but I’m no good at it. I watched videos on it but nothing helps. I want to start filming videos on it on my own maps but just can’t figure it out. Please help me. And if you know what type of camera to use to film that would be great. Thanks!

You might find more help in the Mapping section (
