You are the devil of Vray. Not even chaos group would have known that what you gonna do with their tools. Thank you so much for making these tutorials.

[@Explore-Gobal]

When it comes to tutorials, I've seen very few OPs that direct you to a "free" patreon site, only to find that just about any content, including the scene files to the tutorial are only available with a PAID subscription. You seem to know what you are doing, but your site is a bit deceiving as there is virtually nothing free with one of your "FREE" accounts. Loosen up and give us a taste before charging for everything.

[@digitalesthetics]

best channel for this stuff. I use Corona Render but still find it useful. Unfortunatly we don't have bump material so have to do a workaround for that.

[@scpk2246]

Hi Jonas, can you explain vray camera's Field Of View, Film Gate and Focal Length? What are the relationship of these settings to each other, and how can this be related to an actual camera - im confused on this. -anyway, your videos are always super super helpful 😊

my curvature node doesnt have all the options your does.. why are our nodes dif? dif max version?

[@JonasNoell]

Rather different V-Ray versions

Hello Jonas, is there is a specific reason why in my chase the texture in not randomly set, after fallowing the tutorial? Thanks!

[@JonasNoell]

Did you apply a triplanar texture?

[@ciprianandrus1544]

@@JonasNoell I manage to resolve the situation after I reset XForm of the object. Do you think that in the future you could make a tutorial for dust and dirt material, I am not able to do as I want the transparency of the dust in certain places combined with the texture of the dust. Thanks! Keep up a good work

the most explaind tutorial...

[@ЖекаГребінник]

WOW!!its blow my mind!!!!

[@glmstudiogh]

I’m a VFX Compositor but I’m also learning lighting, shading and rendering. Thanks so much for taking your time to share this knowledge, much appreciated, my materials and shaders in CG have gotten better since I found your page. My question is; Is there a way to include a mask in cryptomatte for decals, cause I used V Ray Decals but the decal doesn’t show ip in the cryptomatte channel. I use Cinema 4D.

[@JonasNoell]

Thanks for the feedback :-) As for the cryptomatte if you switch it to separate by material it should be working. At least it does for me in 3ds Max. In Cinema 4d I'm not sure. If it doesn't work and you think it is a bug you can ask in the support forums for C4D.

great tut as always my friend!

Love from india 🔥😍

[@smukkegreen]

Good stuff, Jonas I use Arnold and the curvature and Ambient occlusion shaders are pretty awesome.

[@JonasNoell]

Yeah I guess it should work quite similar there 😀

[@ghrairioussema5373]

perfect explanation

[@SuperMaimed]

CTRL+drag the node on to the spline, so you dont need to individually pipe the splines in to the node. maybe you already knew that, and did it this way for demonstration purposes :) Good tuts as always. cheers and keep 3ds max alive......... ehm i mean vray. ( I think it is drag first and then push CTRL )

[@JonasNoell]

Yeah will check it out, I normally only work with the Slate Editor for the tutorials, I normally don't like to use it and prefer the Compact one :) Thanks

[@F10F11hm]

This is beyond amazing. Loving your procedural workflow, there's so much flexibility to it!

[@JonasNoell]

Once you go procedural you never go back. 🙂I normally don't find any need to do any unwrapping and don't like to substance painter/designer but prefer to do a similar kind of workflow directly in VRay

[@3DRnD]

I highly recommend your videos for those who want to get into advanced material. Keep up the good work

Awesome thx!

Hi Jonas, can you make a tutorial un VrayRandomizer? Specially on the "steps" option - thanks

Great job!!!

[@kelsenarchioli9843]

Hi Jonas, very impressive. Can we to make this same technique in V-Ray for SketchUp?

[@JonasNoell]

Hi, unsure about V-Ray in Sketchup since I have never used it. But If you have a curvature node and a BlendMtl I would guess you can. Those are no new features and have been in V-Ray for years, at least for 3ds Max...

[@kelsenarchioli9843]

​@@JonasNoell I understood, Jonas. Thanks a lot.

[@addamski]

Fantastic video again mate! I would love it if you could show how to add a Vray Decal on top to make it also look worn down and chipped with the same bump etc?

[@JonasNoell]

I think Vray decal would work better on less complex surfaces. Here it would probably be stretched across all those gaps and details in the geometry and I think you would get a better result just by using curvature or AO

[@addamski]

@@JonasNoell Yeah I understand, fair enough, thanks

[@piergiacomomacri492]

Very nice is the output map necessary even if it's already implemented into vray curvature? thank you

[@JonasNoell]

It depends, in my case I wanted to clamp the output AFTER I multiply several textures on top of the curvature. If I would clamp the output in the curvature node the result would look different in this case.

[@piergiacomomacri492]

@@JonasNoellclear.. thank you for reply

[@pixelquarry]

Very nice overview of the curvature map and excellent workflow pointers. I'm wondering if the 99% thing is something you found out by trial and error or knew it beforehand? Congrats to the 10k subs!

[@JonasNoell]

Thanks, what 99% thing are you referring to?

[@pixelquarry]

@@JonasNoell When you blended the maps you set the transparency to 99.9 instead of 100.

[@JonasNoell]

@@pixelquarry Ah ok, just trial and error basically 🙂

[@andreasmass4492]

Great tutorial! I've been using this method for many years. Although with the VrayDirt map instead of curvature. I still find VrayDirt a better option because I find it more intuitive and easier/faster to manipulate organically. Mostly with just one texture in the radius slot (and adjusting output curve for the right contrast). And a VrayColor map for the occluded color where you increase the RGB value in case the resulting mask is not bright enough. Long gone are the days of Grant Warwick's Mastering Vray... Weiter so und beste Grüße!

[@JonasNoell]

Hi, I have another tutorial in my channel that covers exactly the VRayDirt workflow. It's called Rusty Metal Shader tutorial, you can check this out to compare this to your workflow :-) I like use both V-Ray Dirt and Curvature. They have different usecases for me, for example in animations the VRayDirt may behave weird if other objects suddenly move by closely and interact with it. The Curvature just depends on its own geometry so it's more suitable for animations as it doesn't depend on the objects position and it's position to other objects in the scene.

[@andreasmass4492]

@@JonasNoell ​ I see! But VrayDirt map has the "Consider Same Object Only" option built in so you could make it behave the same when needed. In fact I find the ability to use both very flexible. For example you can leave this option off so VrayDirt interacts with with all other objects. And then the exclude/include list can be used to further specify which objects in the scene affect it and which don't. To be exact there are two exclude/include lists, one for which objects receive VrayDirt at all and one for which objects have an influence on it. There have been many instances where I used this. Just recently for example to generate dirt/sand on car wheels. So you would take advantage of the tire object and rim object interacting and the crevices between them gathering dirt but exclude the car body etc. But having said all that, it only matters what works for each person better and feels more intuitive. For this kind of setup the curvature option might be more interesting (for me) if maybe it's considerably faster than VrayDirt. But I haven't tested the speed between the two directly yet... if it is it might be a better option on scenes with many multi level shaders like these. In the end the biggest slow down though is the fact that Vray always computes all the layers of the blend mtl. Once you have a model with many of these blend mtls you will notice how slow things get during render time. But hey, quality over speed! :D

[@JonasNoell]

@@andreasmass4492 Yeah the thing with the blend material is unfortunately annoying. For animations or when rendertime matters I normally try to built all of this into one VRayMtl. It's a bit more complex and annyoing to mask out different Glossiness, Metalness, Bump, IOR and so on in the same shader but it's possible and speeds up the overall rendering. I would wish that the BlendMtl would act the same way because it would be much more clean and intuitive to keep those shaders separated.

[@andreasmass4492]

@@JonasNoell Yeah, it would be great if they actually managed to "bake" the composite right before rendering instead of calculating all layers. I mean hey, we got a sheen option in the vraymtl now instead of having to use blend mtl and shellac mode. That's a start, right? 😅
