The effect you are describing is essentially why an environment map (HDRI) is used to simulate a real environment. The light source is mimicking the sun which is far brighter and further away than a studio light close to the subject. The even lighting and shadow shapes of objects close together under sunlight matches what you see with an environment texture and image based lighting is written to sample the way lighting works in the real world. So putting your key light in your environment map will simulate sunlight conditions where any punctual light will simulate studio lighting conditions. Subconsciously your viewer will make assumptions about what is outside the frustrum of the lens based on how your light renders because we are used to seeing lighting in both conditions. So your object could look like it was lit by the sun or in a studio by which light setup you use.
True! That is a very good point. The reason why I show the difference here is that, in my experience, a great majority of the people using KeyShot uses HDRI only - Also for shots that would benefit from using physical lights instead. Hoping to show upside of using physical lights with this video.
Hello Esben ! Great videos and tutorials, i really appreciate them ! I was wondering, what specs do you use in the renders themselves, for example these 2 images you've shown here. Like what samples, ray bounces, resolution etc. I'd appreciate it ! Keep up the good work ! Regards
Could you say the HDRI lighting is infinity far away and there is no brightness falloff over distance? Question though: Why did the HDRI shadows get dark as it went to the further spheres?
Wow, you read my mind by making this video, I was trying to find a good way to demonstrate the differences to some colleagues about this, and you nailed it. Great demo. Also, I would love someone smarter than me to create an 'easy' way to translate HDRi pins to Physical lights. Harder than it sounds, I'm sure, but could be a game changer!
@@esbenoxholm thanks for clearing this... Is this the same Threadripper Rig? My Ryzen 5 1600 struggling a lot. Any ways to boost the speeds in interior mode?
@@vikisk.3d Did you try decreasing the global illumination to 1 in case you're not really rendering the interior scene? I guess that could make some difference at least. Nothing else that I can think of which wouldn't work on speeding up any other mode.
Hi Esben! Thank you for the vid. Could you please upload the source file? I am trying to setup the same scene as yours but I couldn't get the same lighting using the HDRI with a single pin. Thanks
Sure. Use whatever you think looks the best for your purpose. The purpose of this video was just to show the difference of using the one or the other :)
Usually it's to remove the 'border' that appears when your environment is smaller than your object. Often there's a hard shadow line that appears, or sometimes the shadows coming off the object calculate strangely. Esben mentions 'artifact' in this video - that's what you're trying to avoid :)
Good questions. As Anuj mentions you just want to make sure that it is big enough to cover all your objects. One thing the size affects though: If you have polished materials with clear reflections, those will change if you adjust the size of the environment.
@@esbenoxholm Sure, I'll put some link here: i-h2.pinimg.com/564x/ce/8d/7b/ce8d7b941524e950ca01cb57585ab977.jpg i-h2.pinimg.com/564x/3b/e5/8f/3be58f64d8588ecb9ca57cf8634659ab.jpg i-h2.pinimg.com/564x/df/82/83/df828385a436f915875a27243bf8738a.jpg i-h2.pinimg.com/564x/2a/ca/15/2aca15db8153b9dd50be92b35bb4c835.jpg In general the dimensions and the type of objects goes from a chair to a small tea box (10x10x10 cm). As a student i can say that is almost impossible to find an exhaustive tutorial for keyshot wood rendering using the wood material of the program or a starting .jpg texture.
what about making a larger area light and placing it further away to make them same. is keyshot an awful software? no usable scale or falloff settings for HDRi environment either? jezaz. what we see is just a difference in scale and distance that should be adjustable, nothing more. you could even set falloff to 0 in the area light and keep the light uniformity but have the different shadow angles.
Hi Constantinos. Good point. It is possible to use an area light to create the look of the HDRI, by bringing it far away from the objects. The point here, as I think most people use HDRI to light their scenes, was to show what kinda look you can get using an area light. I wouldn't say that KeyShot is an awful software, but having a visible falloff for HDRI would be really nice!
I like this kind of short videos, which tells only one topic. It is easier to concentrate. Thank you Esben!
oooh, Esben, what would Keyshoters do without you?
This has always been a confusion till now. Thanx a lot Esben, your videos on small topics are really appreciatable.
Thanks, that is great to hear!
Check out this tutorial by Will Gibbons for tips to set up a dramatic lighting using an area light: th-cam.com/video/3AxYcNMFuKQ/w-d-xo.html
SO helpful! I was just experiencing the overdramatic effect of area lighting in my scene and now I know how to solve it! Thanks for the quick help
super useful! I wonder how did you make that cloudy look on the circle?

This is exactly the video I’ve been trying to find! Thank you so much Esben! Really well explained and thorough. You’ve got a new subscriber :)
A super helpful and straightforward tutorial as always... thank you!
Please keep making these Esben! These are things that I should know, but I don’t. Appreciate it!
Fantastic nugget of info. Thank you for taking the time to share this.
Beautiful explanation. Thank you for taking your time making these easy to digest content!
Thanks a lot for your help ! How can you combine both type for interior rendering ? Which one is the best ?
well done, thanks. Area light 4 life
I don't personally use keyshot, but the difference in how these kinds of lighting should still be useful in Blender! Thanks for the video!
Cool, that's good to hear. I'm not sure how other softwares handle HDRI lighting, but guess it is kinda similar. You are welcome.
Very good test. Good job.

Thanks, David. Appreciate it! Oh, yeah. A 'Convert HDRI to Area Lights' would be a very cool option.
Great, Can I know why you are in interior lighting mode???
Good catch! In some cases, I think the shadows and especially the colors in the shadows looks nicer when using the interior mode.
@@esbenoxholm thanks for clearing this... Is this the same Threadripper Rig? My Ryzen 5 1600 struggling a lot. Any ways to boost the speeds in interior mode?
@@vikisk.3d it is actually the 2990wx threadripper. Don't have any tricks to speed up the interior mode.

Thank you, Esben. What kind of situation would you use area light?
For dynamic lighting setups. Take a look at this video: th-cam.com/video/umnswWAS2vw/w-d-xo.html
Great video! What CPU are you using of its not secret?
Threadripper 2990wx for this one
Super usefull! Thank you again!

Very usefull ! Thanks !!!
That clear ! 🏆👏🏼
An awesome explanation dude!
what are the specs of your computer?
Hi, thanks for your tutorial, but I personally think the HDR environment of keyshot is more realistic
Sure. Use whatever you think looks the best for your purpose. The purpose of this video was just to show the difference of using the one or the other :)
Yes, thank you for your reply
Thank you.
To start with HDR light in keyshot
If the size of the environment doesn't affect the intensity or shadows, what would be the reason for changing the environment size?
Usually it's to remove the 'border' that appears when your environment is smaller than your object. Often there's a hard shadow line that appears, or sometimes the shadows coming off the object calculate strangely. Esben mentions 'artifact' in this video - that's what you're trying to avoid :)
Makes sense @@anujdhawan, thank you

awesome
Really useful, ty! But can you please make a tutorial about wood material in little objects please?
Thanks Mattia. Do you have any reference images of the kind of 'little object' that you have in mind?

Take a closer look :)
Really??? That's not possible.
