Great tut and nice channel. If you look closer at dust on a body shell, you'll see that it's intensity change according to the angle you are looking at. In you scene, you used the same technique for 2 different effects. The one you used is working fine for the mud, but for the dust I think you should give a try to a falloff map, set to perpendicular/away. You'll see!
Hi yeah that’s an interesting idea. I guess if combine both should get some nice result. So to place the dust more on areas facing upwards but also have it affect by viewing direction. Good idea 👍
Another excellent tutorial! You make it seem so easy and logical, but I could never come up with this on my own for my shading networks. Thank you for the inspiration and education you provide! Looking forward to the next one! :)
Please do a detail tutorial on how vray samples + which global illumination is best suitable for which scenario and how to clear noisy renders without denoiser.thanks.
❤as always great tutorial! Using simple shaders like the black one, so the artist can easily see the effect is your best tip ever! We have a snowify script that does something similar but with snow.
great tutorial ✌I've been applying dirt and mud to vehicles for several projects recently and developed a similar approach with layered vraydirt maps (the override material was clever and didn't cross my mind). But I'm working with vehicles converted to VrayProxies and can't get triplanar maps to work with them unfortunately, so I had to develop several work arounds. You might want to incorporate an additional dirt map in the composite map that uses streaks, with a bias in Z. But this can become problematic on a vehicle with so many curves
Yeah the z bias was creating some unwanted results in this case, I was playing around with it for a while. Why you couldn't get VRayTriplanar to work with Proxies? Should work with no issues...
When is the long and detailed course for v-ray materials and lighting being released? Do you need to take all my money now or after it gets released? :)
thank you for these fantastic tutorials, want to ask, if we have an animation, does the distance map for the mud, change and flicker with car movement?
If its driving over a perfectly flat plane then not :-) Otherwise you can choose a UV based approach instead of the distance texture by just using a simple gradient for example.
very nice, however this will not work with animations since the procedural effect will break as the distance change from the floor. Is there a way to bake it ? or maybe use a falloff parallel to world Z ?
I was hoping to apply this technique for Cinema 4D and Vray 6, but annoyingly, you can only plug solid colour or texture maps into the C4D MultiSubTex node, not complete materials.
MultiSubTex is also the wrong node as that is just to layer maps. You have to chose something like a BlendMaterial, LayeredShader or whatever the C4d Equivalent is
@@JonasNoell Aaah, I thought the 3DS MultiSub Object shader and C4D MultiSubTex were the same thing. I wish ChaosGroup would add equal functionality across implementations.
So good! The use of VRayOverrideMtl to clear up the glass kinda blew my mind to be honest. I read the documentation for VRayOverrideMtl, but I still don't fully understand how it works for the reflection and refraction in this case. My main point of confusion is how the reflection override only affected the glass and not the whole vehicle. Wouldn't using the original clean multi/sub object in the reflection slot of the overridemtl affect the glossiness/roughness of the dirt and mud materials?
The Override in this case defines how that material looks in reflections or refractions. So in the Refractions we use the clean version of the shader. If in this example you would put a chrome ball next to the muddy car it would reflect without mud in the chrome ball . That's why I also had to use the clean version in the Reflection Override as in the headlight there is a lot of chrome reflecting itself. So that's why I had to use Reraction AND Refraction Ovrd.
@@JonasNoell Got it! It's starting to make sense, thank you! In this case, what would you do if let's say the vehicle is in a scene where there are a lot of reflections (standing on top of a still puddle, for example, where you would clearly see the vehicle in the reflection), would you get rid of the OverrideMtl and work on the glass material separately from the rest of the vehicle's multi/sub mtl?
@@ThomasMiller3D In this case I would probably select separate the interior from the exterior and apply the clean version of the shader for the interior.
Hello, is there any simpler method to combine all the materials from an object (let's say all the elements on a car) into one multi sub-object material?
It would work unless you deform the geometry of the truck. In this case you would need to use UV maps instead of Triplanar, as the projections would "move through" the geoemetry during deformations. But depending on the shot/cameraangle/animation it would be more or less visible, so maybe it doesn't matter in the end...
@@JonasNoell I think also if the truck animates/jumps above the ground (like off a ramp) the distance texture cause the mud at the bottom to disappear as it gets further from the ground? I guess you could bake it out.
@@nathanmitchell7074 Or you can just link a groundplane that links together with the car. But if your primary usecase is animation then there other techniques which work better in that case.
@@JonasNoell I ask because I am curious what engine is responsible for render previews in your video - is this GPU only, or something else (CPU, CPU+GPU)?
This seems like a good reason for not using Corona ): Apparently there's no way to connect a Multi-Sub Obj into a CoronaLayered Mtl. Do you think there's a way around to make it work?
@@JonasNoell I tried to do it applying the Dirt Map (CoronaAO) in each material separately and it worked marvelous (much more time of course). It's my first decent results using dirt/distance maps. Thank you!
@@albertofigueroa7804 Ok perfect :-) Yeah one by one would work as an alternative, however I like that in VRay I can just just throw the whole MultiSubobject Mtl inside.
Hello, I want to know why there is no model at the bottom of the car, but there are shadows. And there is no lighting in the scene. Why do the car highlights and the background of the picture have gradients?
As long as you just use move, rotate, scale there won't be any issues. If you crash the car and deform the mesh itself then the Triplanar won't work. In this case just use a simple Box UV or something instead. Or spend the time to do a proper unwrap.
Is this possible in Maya with VRay, can assign material id's as a vray attribute but I do not see any way of being able to make that useful with the shaders. Yes could prob get this effect per material but that is a lot of shaders to update and modify for the look dev.
As long as the car keeps the same relative distance to the floor then not. But if the car jumps or something I would use a UV based approach instead for the distance part.

The floor is a matte object :-) And the gradients exist because whatever reflects in there also has gradients built in (sky)
