Spot area lights can be tricky to implement because they don't have a simple physical meaning (condensers, reflectors, shutters, barndoors... they all act in a very different way). However, decent basic controls are fundamental to give artistic control over lighting.

Looks really cool! What would you consider decent basic controls?

Few controls giving a good range of shaping in a predictable way. A way not to implement a spot area is to restrict emission with a cone by each point in the light surface (cone convolved over the area). That makes the light darker and darker as the cone shrinks.

This is incredibly beautiful!

For directionality it is much better to control a spot area light from its target rather than from the origin. You could also scale the manipulator lines to show the distance fade.

I need to do some work on the manipulators, I agree. I need to make one specific to lights, it’s in my todo list. About the cone scale, yes it’s there, I don’t show it, but in the video you can see it just below the spot controls in the UI.

That’s correct. Besides a handful of foundational libraries, it’s all written new.

🇺🇸President Donald J. Trump: "Hamas has become very difficult to deal with in the last couple of days because they don't want to give up these last 20 [living hostages], because they think as long as they have them, they have protection. But I don't think it can work that way, so I'm speaking to Bibi Netanyahu and we are coming up with various plans."

📣📣 SILVER ONGOING DEFICIT 🚨 Silver is the most manipulated commodity. Selling Billions in Silver that they don't own and can't deliver. They have gotten away with this in the papers markets because they didn't have to deliver. Silver is in a deficit so delivery is a problem when you have sold way more than you have. FAILURE TO DELIVER Commodities can't be faked like selling Securities you don't own and can't deliver because it is a physical asset. You can use a loophole in securities to give the illusion it has been delivered but that doesn't work with physical precious metals. FAILURE TO DELIVER IS WHERE EVERYTHING BREAKS

AOC, Kamala, and Hillary Clinton all have to use Fake Accents On The Campaign Trail Because Democrats Are Fundamentally DISHONEST. They don't believe anything. They don't know who they are. They don't know where they're from. The only thing they know is power. So they change your accent in order to gain power based on who they're speaking to. Conservatives have a fundamental bedrock and ethos of who we are as people. We don't have to pander or be ashamed of who we are. We as Christians and conservatives know who we are because we have a relationship with the God who created us. Democrats are lying to their voters and they aren’t going to buy it.

🚨 Jeffrey Epstein says the best traders act on intuition they don't fully understand "If you talk to really experienced and successful traders and you ask them how they know what's going on, they can't give you an answer. They don't know. They feel it. They can feel the way the market's moving. They can feel the way the stock's moving. And that these are not very well-defined terms. Great traders feel it and then act on their feelings. That's the difference. Many people feel it but are afraid because they want a mathematical justification before they take that next step."

AWARENESS AND THE SYSTEM Yoko: The public believes that there's somebody up there who's very powerful because they're rich and they control the media etcetera. And they think, 'Oh, we don't have the control so we can't do it.' And we have this negativism all the time. But that's not what it is at all. They're not powerful because they're rich and they control the media. They're powerful, sadly enough because they are 'aware' and they're trying to keep other people ignorant. If our awareness level gets to the same level as they are, we outnumber them. So there's nothing they can do. John: Who is 'they'? Well, whoever 'they' are - That kept the workers uneducated. That sent children down in the mines in the Industrial Revolution in England. Who tried not to educate people. We're all part of a system, in a way, and 'they' includes us, too. #powertothepeople

Ospreys in this area have an eagle alarm call. When they spot an eagle coming, they make a very specific sound to alert all the other ospreys in the area. Every time I hear that call, I know something crazy is about to happen.

"AI has become a symbol for a technology revolution that people know is changing everything about their way of life and the economy." - Ro Khanna on TBPN today "They feel like they don't have control, that they don't have a full say in what that's going to mean." "I don't think we can be oblivious to peoples' concerns about keeping jobs, and keeping social cohesion, and making sure their kids are going to have a good economic future."

But then you ask: why did they have to do that when none of the American labs did? Well, because they're using partially nerfed chips—that are the only thing that Nvidia is allowed to sell in China because of the export controls."
