Brighter Shadow Caustics in Blender

[@levisarq]

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 KZbin!

[@svvwoo]

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]

Man oh man! Your way of teaching is best

[@_RichardOrtega]

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]

Daniel Krafft did a video a few years back explaining all the nodes, might be slightly outdated by now, but either way kzbin.info/www/bejne/mYKToqeZiN6geqs

[@DerekElliott]

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

[@splatterling4539]

Thank you for mentioning shade smooth. NO other tutorial mentioned this and blender appears to be super picky about that... oh man i am going insane with this.

[@EchoAnime]

What a happy day mister DEREK make a new tutorial. THANK YOU, SIR

[@KaizenTutorials]

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]

good memories indeed

[@musicandhappinessbyjo795]

Damn your voice is so soothing I fell asleep midway. But since the tutorial was so good I got back up and finished the whole video.

[@roykale9141]

Someone recommended me your channel and I can see why. Awesome tutorial

[@joe_fabricator]

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

[@LucianoSalomoni]

Thank's man. This is amazing! Greetings from Brazil.

[@xDaShaanx]

Noice :D New AMSR video with amazing Blender skills

[@georges6591]

He's back!!!!

[@JonasRoenn]

Love this tip Derek! :D

[@VoodooChino]

really nice work man, thanks for all

[@madsnylarsen]

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 :)

[@luiswar3d]

Best Incredible what you share with the Blender community, thank you very much.

[@BAZOMG]

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!

[@sonachine69]

YES!! I need this, thank you, man!🌷

[@melivancolas]

Awesome!

[@DerekElliott]

Thanks!

[@navarrocristofaro]

i will watch it tomorrow, but already hit the like button!

[@guidocanzianijona1129]

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

[@sistasnfashion]

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!

[@DerekElliott]

Some time yes!

[@nico-s5k]

Wow, nice technique!

[@RomboutVersluijs]

Wow wonder how you figured out this one

[@psk01063188636]

Thanks !!!! 항상 감사합니다 !!!!

[@cubedev4838]

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

[@AliKhan-rd6tb]

thank you bro for teaching free ❤

[@manug089]

la sombra de mi vaso es plana, sin ningun tipo de reflejos...no entiendo porque no se ve como en el video...:(

[@restFriday]

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!

[@MrBelenus]

thanks a lot for this great video

[@jabdallah6815]

Beautiful!

[@WenboZhao]

Love it!!!!

[@tuna98khan]

Can you do a training sofa or something like that?

[@moncef1824]

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

[@MarkSmith]

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

[@DerekElliott]

yes! but experiment and see

[@laughing_boothcodm349]

Please make an airpod animation please Derek 🙏🏾🙏🏾😁

[@man_art_man]

It was a lovely tutorial in a style of grandma house 😅😅👍🏻👍🏻👍🏻 You have to sell your voice to some Hollywood Film or Cartoons maker 😅. Love these satisfying and relax tons in your voice. 😅👍🏻😎💪🏻

[@Василь_Галич]

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]

You can do it however! Both are fine

[@Василь_Галич]

thank you@@DerekElliott

[@DuterqueStudio]

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?

[@denisebelanger3711]

是的

[@LucianoSalomoni]

I had the same issue. Solved reducing the lamp's size in Object Data Properties|Light:Size.

[@mrleotheo]

Thank you very much!

[@m3dverse]

Amazing🙌

[@Karanpurohit121]

Nice one!

[@bryjazz3556]

Hey there! I stumbled on your KZbin 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]

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

[@Prodo-r6y]

You are awesome

[@Lightly_Salted]

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]

Yeah this is a huge limitation

[@Lightly_Salted]

@@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]

@@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]

@@_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.

[@Limbo_Design]

[@riccardofissore7996]

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

[@MadManTnT]

Missed your voice :))

[@SeeYouInBluffington]

This doesn’t seem to work. Anyone tried for themself?

[@aaarThur349]

😍🤩

[@Olivsgreen]

Legit started laughting at the "you can add in a new website"

[@DerekElliott]

Haha tried to keep that one smooth

[@rafaalejandro1806]

If you are not getting the caustics try using CPU instead of GPU Compute

[@jakem950]

im on cpu and get none of that

[@shilpiarora7551]

cool

[@dgffggfhghgh]

I NO HAVE SHADING TAB. BIG KZbin MAN SAVE ME

[@DerekElliott]

You have to make a window and change the type to shading or use the workspace preset at top of screen

[@Amor.artist]

plz make tutorial video on sci fie envoirment

[@liamhalsey2938]

really happy I found your channel, Thank @ducky3d
