Nvidia has just announced that the upcoming plugin version of Mental Ray for Maya will be free for viewport and single-frame rendering.

There are various other 3rd party render engines available for Maya. This is not only limited to rendering the final product, it incorporates also materials, lights, camera's and even geometry.įor more information: Mental ray rendering The engine has a high level of flexibility which makes rendering in various styles (from photo realistic to cartoon style) possible. It is a 3rd party plugin developed by Mental Images and integrated in Maya. Mental Ray for Maya offers all the features traditionally expected of photo realistic rendering and includes functionality not found in most rendering software. Information on common render settings can be found in Rendering. By default Maya comes with four different render engines: There are numerous render engines that can all give you a different look and feel and have all their own limitations, which makes it important to choose the right one. The specific settings and render engine you use have great influence on the final result and your way to get there. In this stage you will transform the three dimensional model into a 2D image or movie.

Rendering is one of the final stages of the 3D computer graphics design process.

How to enable them is covered in the pages on each render engine. This requires Ray Tracing to see where the reflections go. Specular Reflections will only be calculated when you enable them. Glossy reflections are only available in a few render engines such as Mental Ray.ĭiffuse reflections won't be calculated by default and some render engines are unable to render them all together. Specular reflections are reflections of shiny surfaces (specular shader, such as Blinn or Phong). It's important to know there are three main types of reflections:ĭiffuse reflections are reflections of diffuse surfaces (diffuse shader, such as Lambert). Most render engines allow tweaking these different parameters, to optimize render speeds: if you're not interested in reflections, there's no need to spend costly calculations on them.īy default most render engines won't consider reflections of light.

Other options are rays to determine reflections (reflecting objects) or refractions (transparent objects). A ray may be shot towards a light source to determine if the spot is lit or in shadow. From there several possibilities may be evaluated. When a ray hits the first object it meets, the ray stops. With raytrace rendering, rays are typically cast from the camera, one for each pixel. Actually, the calculation is done in exactly the opposite way: from the camera to the object to the light. The downside is the performance: these calculations are costly.Īs the name already predicts, it traces a ray from its source in a certain direction until it reaches it's destination (or better: a destination), thereby determining the path of light from a light source to an object to the camera. It can give very accurate results and produce realistic images. Ray tracing is a method to calculate the path light travels. When an image is rendered, this is done in a few basic steps.

Instead it's more efficient to go from the camera to the object and then query the amount of light that gets to that specific patch on the object. You may see why a renderer works this way: it may take many light paths to be considered to get from the light source, via an object, to the exact position of the camera. This would typically be the direct light received by that surface. The renderer then determines the amount of light that is received by that patch of the surface. This is covered in more detail in the Lighting section.įurthermore light isn't traced into the camera, but the render engine determines which objects (surfaces) are 'in sight' by looking through the camera. You'll need advanced render techniques to mimic this light behavior. First of all, basic rendering doesn't calculate all possible reflections (bounces) of light from all surfaces (which would be a nearly infinite number of light bounces). Rendering works in a similar way, but not quite in the same way. It 'bounces' of the surfaces until it finally reaches our eye. In the real world, light travels from lights to the objects we see.
