In this video we'll go over a simple trick to make the default shadow caustics in Blender a little bit brighter. Caustics in Blender still aren't super realistic but sometimes that's ok! With a couple little tricks in the shader editor we can help your glass objects stand out! There are still a lot of limitations here but I wanted to share these tricks anyways. Hope you enjoy!

I'm a simple man. I see Derek's notification....drop whatever I'm doing to absorb pure knowledge. Please stick around Sir! Your Blender contents are hands down the best and most creative on RU-vid!

@svvwoo Год назад

ive been trying to figure out caustics for well over a year trying different render engines and watching a bunch of tutorials . finally got it with you . thank you

@rikhari_redelta Год назад

Man oh man! Your way of teaching is best

Damn dude, that light path node really makes a huge difference. To be honest, I just wish I knew what every node did. I just don't have the patience to sit there and figure them all out...and then figure out how they could work together. Thanks for doing this tutorial!

@kameleongreen Год назад

Daniel Krafft did a video a few years back explaining all the nodes, might be slightly outdated by now, but either way ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cQ0qtcSymDI.html

Light path is definitely a mysterious but useful one in certain scenarios like this

@KaizenTutorials Год назад

So I have a question about how the Diffuse ray works… 😜 nah great vid Derek! Really like these results and this is a great simple hack to pimp the shadow caustics. Thanks for sharing! Btw great pic, good memories at BCON 🙌🏻

@DerekElliott Год назад

good memories indeed

"You can add in a ....." lol. Subtle :-). Awesome job as usual Derrk

@madsnylarsen Год назад

great tutorial :). i tried it out and ran into a few challenges, i made my model to scale (14cm tall and 8 cm wide), something i wish would be a standard, 2 meter tall glass is rare ;). I found that the Light-path node made my caustic shadows too dark and un-realistic looking, i still think the caustic shadows are too dark thou, comparing to a real life example... A tip about roughness, if you use "transmission roughness" you retain the glossiness of the object, the roughness would be "within the volume" so to say, great for ex. a smoky-glass with reflections on the surface, if you use the specular roughness the object gets matt on the surface :)

Hi Derek! I love how thoroughly you explain each step in your lessons. I was wondering if it’s possible to create a luxury designer handbag tutorial? Thank you!

@user-jh9vl4vl3s 11 месяцев назад

Thanks for the lesson! For 12 minutes, you make a vase out of a circle, and can you make it out of a cylinder? And why from a circle?

@DerekElliott 11 месяцев назад

You can do it however! Both are fine

@user-jh9vl4vl3s 11 месяцев назад

thank you@@DerekElliott

@tuna98khan Год назад

Can you do a training sofa or something like that?

@m3dlance Год назад

Amazing🙌

@BAZOMG Год назад

Hey Derek I have a note here. Followed your tutorial but I did not got any caustics. I modeled a scene in real life dimensions. Like the glass ist like 10 cm high. The caustics only starts appearing if I scale the glass up to ca. 2 meters. How can we get the tutorial working on smaller dimensions? Thanks!

@restFriday Год назад

Hi ~ Man, thanks so much for sharing. I would like to ask a question, if you add liquid made of glass to the cup, why the scorching disappears completely, this question has been bothering me for a long time, looking forward to your reply, thanks!

@moncef1824 Год назад

Great content as always Derek 🙏 , is there no way to have the same results in eevee? thanks so much

@Lightly_Salted Год назад

Nice werrk Derrk! If only this helped with the lack of caustics from nested dielectrics - all the glass I work with has liquid inside which kills the shadow caustics at the moment.

@DerekElliott Год назад

Yeah this is a huge limitation

@Lightly_Salted Год назад

@@DerekElliott I find I can get some pretty decent caustics with nested dielectrics if I turn off light clamping and filter glossy but the fireflies and noise present an extra challenge. Denoising helps but it often turns the caustics into a blurry mess!

@_RichardOrtega Год назад

@@Lightly_Salted I am still having trouble getting any caustics to show up when rendering through any form of liquid. Even with the light clamping off, and filter glossy off.

@Lightly_Salted Год назад

@@_RichardOrtega I use a shader that I picked up somewhere along the way that uses a similar principle to what Derek is doing here except you use the Shadow Ray to mix between your glass/liquid and a transparent shader (similar to the archvis glass technique). This way you can control how much shadow is showing through (I have the liquid set to 0 and glass 0.3) which allows the caustics to show up better. The downside to this is it doesn't work at all with the new Shadow Caustics because as you turn the shadow down the caustics go with it! If you really want some cool caustic effects you can also look for fake caustics shaders, there are lots of them around.

@guidocanzianijona1129 Год назад

Caustic, both cast and receive, does not show on the Mac version of Blender....any idea how to walk around it?

@cubedev4838 Год назад

Hi derek, can you tell your story how to get client?

@shilpiarora7551 Год назад

cool

@riccardofissore7996 3 месяца назад

Doing exactly the same and I don't get caustics, I'm on Blender 4.0

@MarkSmith Год назад

If you had used an object with sharp angles, would you get a more prismatic effect? Like cut crystal?

@DerekElliott Год назад

yes! but experiment and see

@bryjazz3556 Год назад

Hey there! I stumbled on your RU-vid channel while looking for blender tutorial videos. I am a beginner and have been trying to learn blender for the past few weeks. I have been taking journals worth of notes so far, however I’m not sure if taking notes on tutorial videos as recommended or not. Currently I’m writing down almost everything said in a tutorial video and aren’t sure it’s the best way of learning or if it’s a waste of time taking notes. How did you learn blender and did you ever use notes? Should I only take notes on hot keys? Would love to get a response back on your insight! 🙂

@DerekElliott Год назад

Notes might be good for hotkeys but really just repeat repeat repeat and you will learn!

@DuterqueStudio Год назад

Great tutorial as always. Thanks! Was trying to do the same thing but instead of using a sky/sun I tried with a light point and also an area plane, but it doesn’t seems to work, even with caustics switched on in the light parameter. Is this trick work with somthing else than a sky?
