That does not mean its vast valuable content is lost, but we will stop hosting it on the original website location. For those of you who are searching for the download links of the free Mental Ray software, which we did publish in the forum as well, here you are. We include a copy of the text of the original announcement followed by all the links to the pieces of software. The version 1. The update also fixes a lot of known issues, and improves rendering performance especially for GI Next.

Note, the plugin works in Maya Please notethe plugins are free to use autodesk maya 2018.5 release notes free interactive rendering and rendering of still frames from within Maya or 3ds Max.

The primary purpose of this update is to fix a problem autodesk maya 2018.5 release notes free the original installer, which stopped working with latest NVIDIA driver installers on Windows. At the same time, we also addressed few minor issues in the plugin itself, and in the Mental Ray core engine. For details see Mental Ray and Iray product updates. You are eligible to convert your licenses to perpetual, just contact us by email as mentioned in the FAQ above. The plugins offer the full functionality of Mental Ray no matter if you have a license or not.

We are open to giving out licenses to cover your critical and ongoing Mental Ray projects. Just let us know. You may also download the latest version from our mental ray for Maya website. For release notes and download locations please visit our forum at Now Available: Mental Ray for Maya It is now available in our online store and through select resellers. You can download the free version or purchase full production licenses here.

Need help or advice? Our exciting new version 3. Click here to see the full post on mental ray for Maya! The Physical Area Light has physically-based falloff Light Decay is Quadratic so the intensity of the light compared to the scene scale matters.

It is the number one reason we find when troubleshooting a physically-based scene that renders black or dark. Take the following example. A default polygon plane is created on the default grid. The plane is scaled up to the size of the default grid.

A Physical Area Autodesk maya 2018.5 release notes free is created and moved to 4 units above the plane. Then rendered, noting that the default intensity of the light is Now the light is moved to 10 units above the plane. And barely lighting this plane, so more than that requires more light intensity.

A flashlight can light up a baseball, but it cannot light up a baseball field. This kind of thinking has to start informing your lighting decisions. But once you get used to it, it may actually help you work more efficiently to produce realistic lighting results.

With Light Importance Autodesk maya 2018.5 release notes free LIS on, the area light Samples settings are ignored, and quality of direct lighting can be more easily controlled with the Lighting Quality setting in the Quality tab of the Render Settings. This is especially useful for scenes with many lights. Example using an HDR textured rectangular area light. In other words, the texture is not normalized before multiplication.

The physical area light defaults to use a point light output pattern over the surface area of the light. In order to use a more spot-like falloff for the edges of the area, we need to adjust the area light. It is still a Physical Area Light because it uses the light shape. We are now beta testing Pi-rayour exciting new version 3.

If you are interested, please email mental-ray-beta nvidia. Please state your company, how you use mental ray, and your machine configuration. In addition to registering in our forum, you need to have Maya and the mental ray for Maya plugin installed before installing the beta plugin. The following image is rendered with the latest global illumination GI algorithm in 3. Enter the beta test to find out some great things about the latest GI.

In this autodesk maya 2018.5 release notes free post in a series on mental ray for Maya Render Settings, we assume you are familiar with the concepts presented in the introductory post and the second post on adjusting quality.

We recommend physically-based materials and lights to fit a modern workflow. In this post, we focus mostly on the materials, and we will follow-up with more posts on lights. These materials are designed to work more compatibly with unified sampling, and the simpler UI quality controls.

Autodesk maya 2018.5 release notes free provide the flexibility of balance in adjusting global vs. The Layering MILA material not only provides better compatibility with unified sampling and quality controls, but it also provides simple passes which can help you to adjust the quality settings.

For example, this interior scene using mila materials clearly demonstrates the difference between direct and indirect lighting. The left picture has no indirect diffuse lighting as it is turned off in the Render Setting Quality tab, and the right picture has Indirect Diffuse GI Mode turned On with a depth of 4.

Note that нажмите сюда 2 pictures below are organized in a gallery, so that if you click on them, you can see a larger version. Click on x upper left to get back to this page.

Direct-only lighting Direct and indirect lighting. Then, we can see the relationship between the pass results with respect to their quality. Note again that the 4 pictures below are organized in a gallery, so that if autodesk maya 2018.5 release notes free click on them, autodesk maya 2018.5 release notes free can see a larger version, and step through each with autodesk maya 2018.5 release notes free right, left arrow.

Indirect Diffuse Quality 0. In a sense, this is the indirect quality aside from the indirect по ссылке, autodesk maya 2018.5 release notes free. When Advanced Settings are on, we provide separate Glossy Quality and Scatter Quality controls in case the noise differs significantly between these components.

Note that the material quality settings are relative, so controlling Material Quality will continue to control both glossy and scatter quality. The autodesk maya 2018.5 release notes free так microsoft office 2016 product key 2019 freefree ссылки!!!!!!!!!!! is multiplied by glossy or scatter /23771.txt to determine a quality for each respective component, with all defaults at 1.

Glossy Quality 0. Scatter Quality 0. Note that for the MILA shaders, we provide quality settings by scene. In other words, all autodesk maya 2018.5 release notes free materials перейти на страницу the scene share the settings. This makes it easier to control in a typical scene with many materials, rather than per-shader. It also allows the renderer implementation to optimize better.

Besides quality, we have several other useful render settings that are shared by the mila materials. They are in the Scene tab in the Materials section. This is an enable, for using the clamp level. If off, light transports through the scene in the most physically-accurate way, though with high dynamic range lighting, more quality may be required.

The default is off. When making a material to model colored glass, not only do transmission paths inside the glass need to be colored, but also, if one of those paths reflect inside the glass again internal reflectionit should be colored. Depending on your scene, this may be more or less subtle of an effect visually.

A material with a reflection component could be on the outside or the inside, so the max distance parameter for a reflection component needs information as to whether it is modeling physically-correct internal reflection, or modeling the legacy max distance render trick for the external reflections.

We recommend using colored max distance primarily for internal reflection, when combined with a transmission component, and therefore, make this the default. Microsoft 2013 essentials free the max distance for reflection internally for colored glass. On is the default. If off, the max distance is used for external reflections, those bouncing autodesk maya 2018.5 release notes free the outside of an object, instead of internal reflections. In the Materials section of the Scene tab, we provide a global scaling factor for scatter distances.

It multiplies by the local scale control, if exposed, in the MILA scatter component. Below we show how increasing the scale makes the scatter pass look more like the diffuse pass, with autodesk maya 2018.5 release notes free and less scattering. Front Scatter Pass Scatter Scale For practically good results the scatter pass should look barely noticeable when mixed in with all the other passes.

All Passes Scatter Scale The elemental component structure provides the renderer with this ability. The material can either be selectively sampled or flattenend for a single minimal BSDF representation, and as the depth of a ray increases, more optimizations can occur.

Use physically-based mental ray lights such as the Physical Area or Environment lights. All lights in this section default ссылка на продолжение quadratic falloff for physically-based lighting, and compatibility with the modern techniques including Light Importance Sampling LIS.

In our next post, autodesk maya 2018.5 release notes free will introduce the Physical Area Light, and in another post we will provide more detail for the Object Light, which is a special case of the Physical Area Light assigned to an object for emission. Читать полностью will also provide a post on how to use the newly packaged Environment Lights. The vMaterials are a collection of MDL materials designed for physically based rendering, representing real world materials.

You can register for a free download here. To use the vMaterials for rendering with mental ray for Mayayou have to add the following definition to your Maya. Some materials are dependent on the scene unit and assume meter by default.

You can either change the scene scale to meter or you can convert the scene unit dependent parameters.
