I feel very stupid... how do I start? I got someone on the street to work for me but I cant figure out how to shoot any scenes >.>
There are two ways to shoot scenes: The easy way that pays less and the far more complicated way that pays more. You will begin with the easy way because one cannot open a company, buy a studio and hire a dozen people + gear for $500. So you're in luck.
Go to your home/office (use tab or the building on the map, top right) and go to the staff tab that shows all your models. Now select the hooker. On the very top right of the screen will be a little camera icon that will pop-up with "shoot scene" when you hover over it. Click that. Ta-da!
Now a more detailed explanation: What you're doing is shooting a scene at home (bedroom or office) with whatever crappy cellphone camera or whatever you have laying around. This limits the quality of the scene (and thus it's popularity & income) but requires no extra purchases, actions or crew to perform. It can also be done pretty much any time of day, between 8am and 10pm, and in any location that you've unlocked.
Unlocking locations: There are specialist NPCs that you can hire along the way as extra Personal Assistants. Doing so will give the MC special perks that can't be acquired any other way. If you hire them in a non-porn position they will also give perks to any actual porn models that you hire, as well (but doing so means they won't be doing porn). For example, if you hire the nurse and keep her onboard as a medical advisor then the time models spend in rehab is cut in half and you get STD cure pills for free. There are many others and, IMHO, the non-porn option is always the best one. Anyway, once you hire them then you can free-shoot sex scenes at their place of work. Again, let's say you hired the nurse, so now you can shoot scenes at the hospital.
The hard way: This pays a lot more per scene and generates more popularity, which in turn means more Fans for your business which then translate into more Subscribers once you start your own porn site. However it is also a lot more involved. First you will need to buy a studio. There are two kinds: Photo and Porn (you can have something like 16 porn studios but only 1 photo studio). Then you will need to buy equipment - each studio requires 1 camera and 1 lighting system bought from the mall, and that can easily set you back well over $100K right there for the best stuff.
Then you'll need to hire a crew to work it, and that is close a dozen people for a porn studio and around six for the photo studio.
Once you've got all that crap together, however, you can now do
professional porn that rakes in big bucks and lots more fans. The catch is that each studio (and model) can only do 1 shoot per day, and they're not instant. When you click on the camera icon in the company screen you're actually queing up a scene that will begin the next day (except on Sundays, as always, because we're Orthodox or something). This is true of both porn and simple photos. So a single studio can only do six shots per week, while a MC who plays their endurance right can do 14+ freeshots at home in the same amount of time. But again, quality. With a max level crew and equipment your videos will have something like three times the quality rating as amateur porn from home.
Also worth noting: Only hookers will go straight to shooting porn. All the other girls you meet elsewhere will
require a photo shoot done first in the photo studio. Until then they will not do porn of any kind, period. Of course models have higher stats and fewer mental issues as hookers, which in turns means better quality videos that pay more. The good news is that you can start with just a photo studio - you
don't have leap straight into porn studios. Once a model has released a photo scene they can do amateur porn just fine, and you can keep on scheduling them to do more photos to bring in money afterward (note: this doesn't pay much, but it's better than letting your studio sit idle).
The Website: This is your endgame goal. It's a huge investment but also makes absurd cash when done right. Once it's open you can choose between publishing on the web or the website. Scenes published to the website make
no money directly, but they keep the fans happy. You'll want one scene per day to keep that up. Meanwhile, the number of Subscribers you get is dependent on how many Fans your company has - and fans are added from the day you open your company, not just when you launch the website. I've found it's best to wait until you
at least 50,000 fans before going down the website route, because only a fraction of them become subscribers (roughly 10%, depending on subscriber happiness). Websites make their money off the number of subscribers and, overall, they're pretty easy to please.
So let's say that you've got 50K fans and 5K subscribers @ $10 a month. That's $50K a month and all you need to do is upload whatever cheap, crappy videos you want once per day and you're good. Even just photo shoots will do. Keep that in mind when you've got a Contract model sitting on her butt, because photo shoots have minimal drain on model Happiness (low-effort) so you can probably squeeze a dozen or more per month out of even just one contract model and, being on contract, these cost you nothing extra. A exploit is to contract your ugliest, worst model (because they'll be cheap) and keep on the perpetual photo duty for your website.
Note: A website will need to be upgraded once you hit the invisible ceiling for number of fans. There are 8 levels, and each Webmaster increases the limit by 2, so 4 webmasters = max website. As of this post, the skill level of webmasters has literally no effect on anything in the game, so go ahead and grab all level 1s and don't waste time training them. Dev said this will change in the future, however.
And remember you can keep doing amateur porn at home even while your studios are queued up with a month's worth of photos and porn scenes. A busy porn producer who multitasks is a successful one.
