This is more of a 'tip' thread than a question. I've always had the issue that rendering takes a long time, usually 1-2 hours, and during that time my PC can't really be used for anything else as it takes up all the CPU. When I'm at home and I have free time, I want to play games, not watch a scene render! So render at night, you say? Problem is, I make image series often composed of 20 or so renders, and if I can only render one every night, it'll take forever. No one wants to get up in the middle of the night 5 times to save a completed render and start a new one.
A few days ago, I found a solution.
TeamViewer. It's an app like the IT-support guys use to take over employees' computers. It works on Windows, but also Android. What I do now is this - when I'm at home, I create all my scenes until they're fully ready to render. Usually about 5 of them. Then, the next day, I go to work. At work, I have TeamViewer installed on my smartphone. I use the app to remotely take control of my desktop PC at home, and start the render. Two hours later, I do that again, save render, start new one. By the time I come home from work, I have fully rendered 5 scenes. Without ever physically touching my PC! It's awesome.
