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

@pinywood3077 4 года назад

This should be default

@graphicsguru6003 4 года назад

Of course...it's cool

@lawrencedoliveiro9104 4 года назад

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

@elfferich1212 4 года назад

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!

@A.J.Interactive 4 года назад

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!

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

@FedericoStra 3 года назад

A relevant buzzword in this context is "metamerism". But then avoid at all cost going down the rabbit hole of color spaces...

@vast634 5 месяцев назад

I remember some LED Chrismas tree lights. They appeared pretty bright, but barely illuminated the tree itself. In the end the tree just looked like a bunch of bright dots.

@DanielThiele 3 года назад

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

@marioCazares 4 года назад

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

@ciaranpmryan 4 года назад

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

This is a top-tier RU-vid video aside from the real information and totally useful design concepts. Great presenter too, exceptional really. Really solid, good job. And well lit :)

@Blendercage Год назад

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.

@Trymmelym 4 года назад

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

@JamieDunbar 4 года назад

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.

@lawrencedoliveiro9104 4 года назад

Blender’s source code at intern/cycles/util/util_ies.cpp defines a conversion factor between IES lights and Cycles lighting intensities, which might be useful.

@bakbees 4 года назад

What a well researched video, proper content!

@hypersonicmonkeybrains3418 4 года назад

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

@aluxado 4 года назад

Very interesting video and plugin! Coming from a photography background, having some explanation of how Blender manages the power of the light is very useful! And it's great that this is matching with the awesome Photographer plugin that we're already using with great satisfaction!

@GenericInternetter 4 года назад

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!!!

@MrSkarman 4 года назад

@g3x978 3 года назад

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.

@stuartwakefield244 3 года назад

@lawrencedoliveiro9104 4 года назад

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.

@lawrencedoliveiro9104 4 года назад

7:42 Yup, the intensity of solar radiation at the surface of the Earth, in fine weather, is a kilowatt per square metre. That’s why people get so excited about solar cells. But it’s worth noting that’s total energy, not just visible light.

@hazandthej 4 года назад

@cg_cookie 4 года назад

@timur7381 3 года назад

Got both this one and the photographer) I should've gotten the photographer addon ages ago, been doing photography for a while now and it would probably make it easier working with cameras in blender now :D looking forward to checking this out. I actually wanted to pickup the lighting addon cause I'm working on a scene now and default lights just don't look right to me. I'm a noob though, so I dunno if it's just my hands, but i'll try to fix it with Extra Lights)

@jorgemdahuar 3 года назад

JISUSCRAIST!!! Jonathan, I just can´t thank you enough for your amazing Add on , it is not only deliciously intuitive but also correct, congrats.....

@cactustactics 4 года назад

Heck dude, this is great work, thanks! I wonder if there's any chance of Blender including any of this as standard, at least more realistic defaults and the option to use lumens as units

@lawrencedoliveiro9104 4 года назад

7:13 Fluorescent lights are not black bodies, though. The mercury vapour ionizes, emits UV, which hits the fluorescent coating on the bulb and is re-emitted as visible light.

@marcus_ohreallyus 4 года назад

This stuff is good to regardless of which software you use

@Sport6000 Год назад

Very informative! Though I'd recommend using a "De-Esser" for the audio as they were a bit aggressive throughout the video.

@lawrencedoliveiro9104 4 года назад

3:04 That washed-out effect is a common hazard of what you might call “naked emission shaders”. That is, objects with emission shaders in their materials that are directly visible to the camera. I can think of two ways to avoid the problem: 1) Cheat. Use a Light Path node to adjust the emission strength, keeping it low for camera rays and high for other rays. 2) Use a translucent shader for the visible lamp structure material, and hide the actual light emitter behind or inside it. This way you can preserve a lot of detail (bump map etc) in the appearance of the “lamp” object, even with the light set quite bright.
