Two crucial things are missing: 1. In the first Principled BSDF example change the Base Color value to 1 (by default it's 0.8 - that's why the glass looks dark). There is no difference at all between Glass BSDF and Principled BSDF (only the default value of the Base Color). 2. The most important thing is your render settings. For realistic glass rendering you MUST crank up the Light Pass bounces for Glossy and Transmission. Set the Total, Glossy and Transmission max bounces to 48 for example and see the difference :) If you're using the volume too - you should change the volume light bounces. By default it's at 0.
actually there is a slight difference between the Principled BSDF and Glass BSDF, its differences in the base code of each shader but the differences are very miniscule to the viewer, but there are some
I have reviewed all your videos, you are doing something that many people do not do. I think in the future you will have at least a million subscribers :)
Very nice information. If I may be so bold, I would like to offer a suggestion for improving your videos (please take this in a good way -- I'm not trying to be mean, just helpful). When you're just talking -- take your hand off the mouse and keyboard. Constantly moving things around on the screen, zooming in and out, and fidgeting gets confusing. You see -- in tutorial videos when someone is doing something on the screen it means we're supposed to pay attention to what you're doing, because it's important. But if you're just fidgeting -- it's confusing, because nothing seems to line up to anything you're saying. So... a good thing to work on as a successful TH-camr is learning to talk with your hands off the keyboard and mouse. It lets people know you're simply instructing them verbally and that there is nothing they need to focus on just yet. Once you start clicking on objects, the viewer will pay attention -- so make sure it's relevant. This is simply one of those "less is more" tips. Anyway -- please accept this as nicely as possible (I'm really just trying to help and want to see you put out more awesome videos). Thanks again for the lessons on glass.
Nicely explained and simple,but the IOR on some shaders are off a bit,glass is 1.5-1.7.I'm using a 5th option for glass shader,try combining Light path with shadow and diffuse ray plugged to math node plugged to factor of mix node with glass bsdf and transparent bsdf in mix shader then to output.
Thanks! The thickness of the glass is not visible, for example, in corona render, it allows you to give a thickness color. I think we still need to use the volume parameter.
Very nice, Wenbo! You know how can I export glass in transparency for use in different images whith different colors? My render always gets black, I dont know why.. cheers!!
The glass will reflect the environment, you cannot export a transparent glass without having the reflections of the environment. It’s simply impossible to do🤦🏻♂️ spending some time working on lighting your environment or the surrounding environment of your glass
Dear, first of all, thanks for your videos, it's help me a lot to understand more about blender and blender light. May I ask a plug-in which you use to show a small preview on top of a node?
First , you need enable Node Wranglar addon in you blender, got to edit/addon then search node wrangular addon, and enable it。 Then you left click on the images texture node or any other note Hold shift and control and left click to preview. If you are asking the default text preview founction on each note. It is a addon called Node preview. links here blendermarket.com/products/node-preview
@@WenboZhao i saw multiple of your videos... but can you please make an video of lighting on glass material as im an 3d modeller of perfume bottles . so i find much difficult to give them soft lighting so that each and every part of product get visible... can you please guid me

This is so encouraging！ thanks a lot！
best glass texturing video, i need to make a glass less dark, and more transparent for render presentation purpose, thanks mate
You’re welcome ☺️

sounds very interesting！ would you mind to share your node screen shot？
@@WenboZhao happily will share,but don't know where, do you have discord? if you do MD me astrobat#7948
You can DM me on Instagram if you can:)
Thanks for nice tutorial
Thank you so much for the tutorial!

useful!

node preview I think
@@WenboZhao thanks :)
Isn't that glass dark because by default Blender "white" isn't fully white?
That’s part of the reason, lighting is the big deal and the environment
@@WenboZhao I do agree. :]
Hello, Wenbo! What are you think about using PBR textures of glass?
That works well if you can find something that works, I never found a good one
what addon allows you to display images above the nodes? Thanks!
It’s called node preview, you can get it from blender market
Where did you get those fingerprints from?
Any texture website, search for surface imperfections
How can I enable that node preview ?
First , you need enable Node Wranglar addon in you blender, got to edit/addon then search node wrangular addon, and enable it。 Then you left click on the images texture node or any other note Hold shift and control and left click to preview.

@@WenboZhao ouu actually I am asking about that node preview add on.
how to find greater than node... in blender 3.2 i find alottt bt its useless
search math node
@@WenboZhao yupp got it ... tysm sir... its awesome ❤️❤️

whats your PC specs?
Processor Intel(R) Core(TM) i9-10900 CPU @ 2.80GHz 2.81 GHz
Installed RAM 32.0 GB
System type 64-bit operating system, x64-based processor
It doesn't say how they made it transparent in the first place... they skipped an intermediate step.
