Hello!
I'd like to try to create my own HDRI lights in Daz...problem is, I really don't know how. I've messed around with multiple distant lights and some spot lights, and intensity, and color...Still looks like something is missing.
Dose anyone know of a good tutorial?
Thanks!

Looks like, on contrary, that there are too many things: HDRI works well as a single light system. Sorry, I've no time just now to get tutorial links around here (there are lots!) , but I shall try to come back with. I was like you a month ago, and I can tell you in advance that it''s a famous trip.
Immediate tuto:

1. remove all lights and get back to default D|S zero light. 
2. To use HDRI, you need a Light shader plugin: Go to DAZ and buy some: My prefered is PENDRAGON, or OMNIFREAKER also. Just go to Daz, type HDRI in the search field, click GO, and have a look at the result. Read attentively all items. For first timers, that allways more instructive than trying to follow a tutorial whatever it is. Also on the Daz topic read the up-to-date hot Pendragon forum. 
3. Install your plugin (Pendragon has an excellent user manual)  and enjoy, there you are.
   After a little skill with using your baby, you'll feel the need to get some HDRI additional pictures for various effects. You'll find already mid-day HDR libraries, night HDR libraries, sunset, hot, pale, and so on, but that's for later. 

Some additional points:
-prepare yourself to spend rendering duration times multipied by ten (at least).
-IBL-HDRI lighting works fine with externals, less easily with interiors, and could be really decieving for portraits if managed by clumsy beginners. 
-never try to produce your own HDRI-s, tools for doing that exist, but are not still friendly enough. But they are coming soon, just wait for some weeks for that.
Friendly, locusSolus. 
 

The two plugins locussolus mentioned are UberEnvironment and ahEnvironmentLight.

Pendragons shader pack actually has an early version of his ahEnvironment light that is now in his commercial plugin.

The free shader pack would be a good way to play with the HDR capabilities that these plugins add to Studio before spending money.

I did a quick run-through with Pendragons Shaders over at  the dazartistsguild.com:
