I watched many videos about caustics, but yours was the most helpful, you explained everything pretty well! Thank you!

[@paulmarshall3053]

I always learn something new from your videos Jonas! Thank you man.

[@JonasNoell]

That’s great, I always learn something new making them 😃

[@Hartproduktie]

Very cool, thanks a lot! Tutorial is awesome thanks a lot, always learn something new

fvorite channel on YT thx Jonas

[@diogomachado9381]

Hey man, love your videos, I have a question about how can I approach this kind of caustics to work with condensation drops scattered in a can for example, all the tutorials that I see are on how to do caustics in large scale objects, from time to time I have some trouble to get this caustics to work in small scale, do you have any tips about it? tried on vray, corona and redshift, no one seams to be able to handle this.

[@Dheeraj_Mahajan]

This tutorial is awesome thanks mate ☺️

[@L3nny666]

nice tutorial as always. have to say that the blueish tint in swimming pools is achieved through blue tiles and not by tinting the water. so i wouldn't go for that look.

[@F10F11hm]

Amazing tutorial as always! I have a question, can I render the caustics pass seperately faster somehow for compositing purposes? Would it work properly if I used Vray's override material? One more request - could you dedicate one of your tutorials, even a short one, to proper PBR & Metalness workflow? Or physical shaders in Vray, so that maps from Substance Painter/Designer or Megascans can be used correctly? I'm finding this a bit confusing, in Corona for instance Physical material is now completely separate from the old glossiness based mtl.

[@shivamkhare9543]

Loved your work, needed some suggestions for Desktop Processor for Rendering and ArchViz purposes.

[@JonasNoell]

Depends on your budget I guess. The more cores the better

[@martindione386]

Shivan Khare, if you're tight on the budget, I would suggest a good AM4 motherboard for AMD Ryzen and the best CPU you can afford, you'll be able to update it later up to a Ryzen 9 5950X, which is comparable to a 24 core Threadripper in vray rendering. If money is not an issue, wait until Intel releases the new lineup and see how it compares with the new AM5 Ryzens

on vray 6 does not have the option "affect shadows" what i can make to caustics work in water? have anoter option? someone help me please :(

[@JonasNoell]

This tutorial was done in V-Ray 6, so it does have the affect shadows option.

[@SerhatK.]

Hi Jonas. In the corona renderer engine, there is an option to not reflect the chaostics on every object (include ve exclude). Is this option available in vray engine?

[@JonasNoell]

You can disable or enable the caustics effects for each object separately if you mean that.

[@SerhatK.]

@@JonasNoell How do we do this. Can you make a video for vray 🙏

[@cappuchino7336]

Very cool, thanks a lot! Can you please tell me what processor are you using? what a monster ? ))

[@JonasNoell]

That's a Threadripper 3990x

[@khanhduynguyen7869]

Thanks for amazing tutorial video. Can i get this scene file for light setting ?

[@JonasNoell]

It' on Patreon

[@gogitatsintsadze]

Thanks, it's a cool lesson. You can do a tutorial on the underwater effect? thank you

[@JonasNoell]

What underwater effect do you mean?

[@pixelquarry]

I like the new chapter style 👍 Are you going to make a tutorial on how to fake those render heavy caustics?

[@JonasNoell]

No real good option to fake it in my opinion. If the objects are not moving I would probably just save it out in a map like shown at the end of the video…

[@eclairesrhapsodos5496]

How to enter vray properties? I have black caustics, no matter settings, I use Vray 6.

[@JonasNoell]

Hard to tell from this description. You can enter the properties with a right click on the light to change the caustic subdivs. You can also enter the render globals and navigate to the GI tab for the caustic settings.

[@MCruz-vg1ih]

thanks for the tutorial!!!! :) do you think is possible to make a cracked ice with parallax depth shadder in vray? i know is possible in blender and UE but i haven't found a way to do it in vray/3ds max

[@JonasNoell]

There is a video in my channel about how to use Parallax Occlusion in V-Ray

[@MCruz-vg1ih]

​@@JonasNoellbut is it possible to replicate this kind of effect?: kzbin.info/www/bejne/ZoHFgmulqcdsadk

[@nomad11811]

it seems vray gpu can not make caustics effect?

[@JonasNoell]

Yes, progressive caustics currently not supported by GPU

[@jaloliddinyaqubjonov6988]

you gave me 3dsmax???

[@JonasNoell]

Sure here you go

[@jaloliddinyaqubjonov6988]

Please

[@iamski]

Jesus christ dude, what are you rocking a 64 Threadripper!?

[@JonasNoell]

Yup 👍

[@JonasNoell]

Totally worth the investment if you are doing this kind of work professionally and time is money

[@iamski]

@@JonasNoell Yea I'm intimately aware. Now it makes so much sense why you always have super fast preview renders during your tutorials. Just outa curiosity, what GPU you using? And you ever play with RTX mode assuming it's an NVIDIA card, and how does it compare.

[@JonasNoell]

@@iamski I budgeted on the GPU, a RTX 3060TI, which at the time I bought it also was kind of expensive due to chip shortage but afaik the prices are more reasonable now. Never used it for GPU rendering,, it's only fo the viewport. In fact I rarely tried out VRay GPU so far as I would need to inviest heavily if I want to have a setup that would make sense to use as an alternative to the Threadripper. I think you either go CPU or GPU, you don't invest in both and then have 2 setups, because you will be only able to use one at a time 🙂 I also edit my tutorials, so sometimes rendering is speeded up. You can check the progressbar in the VFB if you wanna know how long something really took on my setup 🙂

[@iamski]

@@JonasNoell I always do brother, thanks again :)
