How physically based, photometric lighting can improve 3D renders + FREE Blender addons for it
Показать описание
Introducing physically based, photometric lighting for Cycles and Eevee. Learn about the strength and color of lights and how those two properties interact.
You're a true hero to the blender community. When I just got started I was always fiddling around with lighting for hours and hours and would end up being confused because it wouldn't look very real, after all that wasted time. This is the answer to all of my questions regarding this. Thanks!

I am writing an entire book about color and light and zou are the first Artist on Youtube actually learned something from since my Masters Degree about 9 years ago...

Wow, this should be in the Blender default addons!!!

1:10 The technical term for that soft shadow edge is the “penumbra”.

Hey, physicist here. Note that sometimes light is even more complex than that: even with exact temperatures, wattage and so on, an LED lamp will only look like the sun if you stare at them directly, not at the things they light up. The full spectrum of LED lamps is still different, and different materials (paints, plants, tissues, tinted glasses) can look very different under two "matching" lights.
Oh and there's polarisation, but that only matters if you want realistic looks through sunglasses or something, otherwise just adding a bit of color filtering would be enough to mask any apparent effect it might've had

I really liked how you used scientific facts to make your add on, and I’m really great full that you have a free version! I’m currently a student so I Can really use these type of things!

I found this addon just this morning( Oct 3 2022)while surfing around Blendermarket. I saw this video (very nice information, btw) and I bought it immediately.
I built some cool light textures using the node setup you provided in this video, but the fact that you’ve organized so many lights and settings overwhelmed me. I had to have the lot.

This video proved once and for all that you have to be a genius in order to work in 3D

thank you for this video! based on this advice i went to me eevee settings, changed exposure to -9, gamma to 1.2, and set my main sun light to 500 strength. it works amazing.
if i want the "overbrightness" look, i can still increase my light to 1000, on the other hand if i want smooth, dark looks i can set it to about 100 or 200. it works amazingly, thank you!!!

This is mind blowing... A lot of this stuff needs to be integrated into blender as standard especially the default scene.

Thank you!! This lighting stuff always drives me nuts and I've never been able to figure out what measurements Blender's lights are in.
Here's to hoping this addon will eventually get integrated into the main Blender build, but until then, I'll go grab your addon.

Thanks for this video! I was beginning to learn this as well during ACES research and so with real world scale scene I'm not afraid to even crank my sun and sky to 400 and 30 and use exposure to bring down. Makes a huge difference in light bounce

I love the Photographer addon. It’s super useful.
I’ll definitely be getting stuck into some of these lighting setups.

This was amazingly informative! I'll probably rewatch a couple times. Very well done!

What a well researched video, proper content!

12:23 Also, part of the shenanigans with studio lighting could be to simulate non-inverse-square intensity falloffs. Blender has alternative falloffs available as an extra built-in node type.

Such a beautiful addon! i always knew that the blender default lights were wack, and have rarely seen tutorials on using nodes for lights. Lighting is where my scenes always fail! So I am really excited to give this a try.

Dude you’re a genius. Love your enthusiasm and drive here

I like how you literally said "blip" and then bleeped it out instead of swearing :D

linked sky texture alone is kind of a big deal. Thanks for doing that! I'd always wished that was something Blender had as a default feature
