V-RAY 5 FOR 3DS MAX

Thank you very much! Works great. All other was perfect. But when I run this script nothing happen. Can you show me how to use this script?

Thank you very much sorry about my poor english. There is only one thing that would come in very handy. I dont know if you are still able to do this, but it would be a great feature to convert only the selected objects materials. Skip to Main Content Area.

Submitted by blaxxun75 on Fri, Convert selected objects material only Hello, I really like your script! Submitted by jamoka on Mon, This page introduces you to the VRayMtl, which is the major building block for most shading networks in V-Ray. This material can be easily set up to simulate a huge variety of surfaces from plastics to metals to glass and more by adjusting a handful of parameters.

Diffuse Color — The diffuse color of the material. Note: the actual diffuse color of the surface also depends on the reflection and refraction colors. You can also assign a map by clicking the check board button. This way you can create a material that has a non-uniform opacity. Opacity mode — Controls how the opacity map works. For more information, see the Opacity mode parameter example below.

Normal — The opacity map is evaluated as normal: the surface lighting is computed and the ray is continued for the transparent effect. The opacity texture is filtered as normal.

Clip — The surface is shaded as either fully opaque or fully transparent depending on the value of the opacity map i.

This mode also disables the filtering of the opacity texture. This is the fastest mode, but it might increase flickering when rendering animations. Stochastic — The surface is randomly shaded as either fully opaque or fully transparent so that on average it appears to be with the correct transparency. This mode reduces lighting calculations but might introduce some noise in areas where the opacity map has gray-scale values.

The opacity texture is still filtered as normal. A texture map can be used for the self-illumination color by clicking on the check board box next to the color slider. Self-Illumination GI — When enabled, the self-illumination affects global illumination rays and allows the surface to cast light on nearby objects. Compensate Exposure — When enabled, the intensity of the Self-Illumination will be adjusted to compensate the exposure correction from the VRayPhysicalCamera.

The renders below show a blow-up of the tree to better show the effect of the different modes. Note that in the first two renders the opacity is blurry because of the texture filtering. The render time is very good, but the increased sharpness can increase flickering in animations. The BRDF parameter determines the type of the highlights and glossy reflections for the material. This parameter has an effect only if the reflection color is different from black and reflection glossiness is different from 1.

Reflection Color — Reflection color. Note that the reflection color dims the diffuse surface color. For more information, see The Reflection Color Parameter example below. However, this will not produce physically correct results.

For more information, see The Reflection Glossiness Parameter example below. Lower values will render faster, but the result will be noisier. Higher values take longer but produce smoother results. Note that this parameter is available for changing only when Use local subdivs is enabled in the DMC Sampler Settings. Some materials in nature glass etc reflect light in this manner. Note that the Fresnel effect depends on the index of refraction as well.

Glossy Fresnel — When enabled, uses glossy fresnel to interpolate glossy reflections and refractions. It takes the Fresnel equation into account for each "microfacet" of the glossy reflections, rather than just the angle between the viewing ray and the surface normal.

The most apparent effect is less brightening of the grazing edges as the glossiness is decreased.Expand all Collapse all. VRayMtl is a very versatile material that allows for better physically correct illumination energy distribution in the scene, faster rendering, and more convenient reflection and refraction parameters. This material can be easily set up to simulate a huge variety of surfaces from plastics to metals to glass and more by adjusting a handful of parameters. This parameter can be mapped with a texture in the Maps rollout.

This parameter is not available when the renderer is set to GPU. This example demonstrates the effect of the Roughness parameter. They can be used for generic plastic for the plastic backs of computer monitors or laptops in a meeting room, or for the car tires in a scene where the cars are somewhere in the distance, etc. Controls the sharpness of reflections. A value of 1.

Some materials in nature glass, etc. Note that the Fresnel effect depends on the index of refraction as well. Note that intermediate values between 0. This parameter can be used with PBR setups coming from other applications.

The reflection color should typically be set to white for real world materials. Scenes with lots of reflective and refractive surfaces may require higher values to look right. Note that this affects total internal reflections too when refractions are computed.

Any value above zero enables refraction. Enabling this option and lowering the value widens the dispersion and vice versa. Note that currently, this works only with clear non-glossy refractions. Scenes with lots of refractive and reflective surfaces may require higher values to look right.This value can be a flat color or a texture map. This value is multiplied with color, therefore by default 1, the final color equals the diffuse color.

If weight is 0. This is mostly used as a silhouette technique for leaves, branches, and people. Hard surfaces like metals are usually rendered with the default value of 0, causing the object to look brighter at front angles.

Rough materials like skin, rubber, and cloth tend to look more flat because they scatter light diffusely from every angle. Notice in the simulation how by increasing roughness the objects receive a more flat look. This value can also be higher than 1.

In the simulation you can see that by leaving this attribute by default Off, the entire scene, including the light bulb, becomes darker. This type is mostly used for plastic. In more diffuse materials reflections gain some coloring. Skin for example reflects a subtle bluish color, rust a brownish color; generally all reflections are slightly affected by the overall diffuse color and simulating it in the render adds realism.

Since VRay shaders are energy conserving, reflection subtracts diffuse, this means that the more reflective the material become, the less diffuse color it emits. Reflective materials cast reflection rays into the scene to determine which color to render, if they hit another reflective surface they bounce off again to determine the next color.

In this simulation you can see how by turning this attribute Off I am able to blur only the roof highlights while leaving reflections sharp. By default 1 reflections are glossy sharp like a mirror. The rougher a material is and the less glossy matte its reflections are, resulting in blurred reflections.

Notice in this simulation how by increasing blurriness noise starts to appear, to solve this increase reflection subdivisions. The blurrier reflections are, the more subdivisions they require to render smoothly and consequently increase render time.

Be careful not to use interpolation in animations as it results in excessive flickering and grid like pattern looks. In this example the floor is rendered with a glossiness value of 0. This states that materials reflect more when viewed at low angles than from the front. In this simulation you can see that by turning this attribute Off the car is equally reflective at all angles and therefore appearing unrealistic.

The reason why these two values are connected is because in real world the degree of reflected light is proportional to the degree of refracted light. In this simulation, with this attribute turned On, the statue is rendered with both reflective and refractive index of 1. Be aware that turning this attribute Off does not produce physically correct results.

In this example, by increasing the reflection IOR means that the material becomes harder, like metal, resulting in stronger front reflections, this should inevitably also cause refractions to become more distorted, and not left unchanged. A value of 1 causes no change in direction, meaning that it has the same density as air. The harder the material, like chrome and metals, the more it reflects at angles facing the viewer and therefore higher IOR values are required.

For softer materials like fabric, where reflections are seen only at low angles, lower values are required. To solve this problem reverse its Normals or turn On this attribute. By activating this attribute you can set a distance at which these rays stop travelling and instead render the shaded points as non-reflective.

This technique can be used to eliminate unwanted reflections coming from distant objects. Notice how the lighting and reflection pass becomes visible in the window reflections.As I've just started to learn I'm facing some problems, today I'd like to ask your help about the following one.

I'm trying to make a simple composite, a basic greebled cube over a plane. I added a Vray Mtl Wrapper to the plane with the following settings:.

By the way I've noticed that turning on the Refraction to maximum white prevent the cube to receive color reflection from the plane, even though I guess it's supposed to don't affect the cube. It works until I add a Sun Light to the scene. Then I can see a smooth subtly gradient of light on the plane:.

I'm not entirely sure I understand what you are trying to do, but I can tell you that you did setup the MtlWrapper coreectly. You could have also just made these adjustments in the VRay Propertins menu of the objects you want to matte. You really shouldn't have to make it fully refactive to remove color, but there is an occasional need to un-tick Receive GI.

As to any additional tips: You could also try selecting your Vray Sun, hitting the "Exclude" button, and then adding the plane that you see the color gradient on. The images aren't bigger than that, that's why you can't open them.

VRay material to Standard material

It was meant to be just a detail of the problem. I'll try your advice on the Sun Light as soon as possible, in the meantime I'm wondering if excluding the plane from the Sun Light will also prevent the plane to project the cube shadow. If I don't use any material on the plane, but just tweak the vray object properties, it seems to work:. I've got rid of that gradient bleeding on the plane unchecking Receive GI.

I had to do it both on the vray object properties and the wrapper material. By the way, unchecking Receive GI takes the sun light color out from the shadow, it would have been nice to have a workaround for that and save the GI on the shadow. There are some workarounds for this issue.

But what I'd do is set the base material color in your wrapper material to a neutral gray After all, color bleeding is a natural thing. I try to stay away from "artificial workarounds" You could also play with the color mapping settings.

Some of them can handle this bleedings but they also have other "side-effects" to consider. Other option is the vray material overide, where you can set a diferent material for the GI's response.

I couldn't maximize your images to see what was going on in your image. Thank you Corey. Basically I'm just trying to compose the Cube over a picture. If the images aren't clear enough I'll post bigger images soon.VRay Dirt is a texture map that can be used to render ambient occlusion.

This pass is useful particularly in postproduction for example for 3D architectural renderings to add contrast to the image by darkening corners or areas between close by objects.

Rfactor f1 2004

In this tutorial the Vray Dirt texture is rendered as a render element. The simulation goes from default black to various different colors. It might add some realism by using a slightly dirt looking color like brown. If the ray dies off before it reaches a shaded point, then the latter is considered to be an unoccluded area.

In the simulation you can observe how by increasing this value the occlusion on the ground seems to gain the shape of the car, as if it was casted straight down from it.

It is recommended to use multipliers of 2, such as 8, 16, 32, etc. The wider the occlusion is spread, the more it renders noisy and therefore more samples are required.

This parameter can be used to simulate the effect of dirt being more visible in a downward direction, like dirt dripping down from walls or objects. In this case the tires are one of the few elements visible because within their gaps, rays are both casted and received from the same object.

By default occlusion is only calculated on the side of the Normals. In fact, polygons are not allowed to cast occlusion on themselves. In this simulation, by turning this attribute Onthe tires gaps become brighter because they no longer self-occlude.

In this simulation the car is rendered with V-Ray Sun and Sky.

See the VRay Mtl tutorial to understand better the difference between these reflection models. In fact you can see how this front wheel is the only one not casting shadow on the ground.
