It requires little setup compared to other renderers. The principal approach of the iray renderer is time-based: You can specify the length of time to render, the number of iterations to compute, or you can simply launch the rendering for an indefinite amount of time, and stop it when you are satisfied with the appearance of the result. The iray renderer supports Rendering Elements Separately. See iray Render Elements.
You can use a section plane to create cross-sectional renderings of models. Early iterations of the iray renderer appear more grainy than the results from other renderers.
The graininess becomes less apparent, the more passes you render. The iray renderer is especially good at rendering reflections, including glossy reflections; it is also good at rendering self-illuminating objects and shapes that cannot be rendered with as much precision in other renderers. However, the result is not the same as hardware viewport shading: The computation carried out by the iray renderer is physically correct, and the result of a hardware-assisted iray rendering is the same as the result when you render using the Central Processing Unit CPU only.
A rule of thumb for GPU usage is that one gigabyte GB of memory can store 5 to 10 million triangles 5—10M of geometry. If textures usually shared among face triangles can also fit into GPU memory, that improves rendering performance as well. The performance of a ray-tracing renderer such as the iray renderer is relatively independent of how complex the scene geometry is. The complexity of light paths is more important: A candle in a labyrinth, or light rays diverging from a narrow window, will take longer to yield a good-quality rendering than light shining through a broad skylight or picture windows.
As with other renderers, performance is also proportional to the resolution of the rendered image. The complexity of materials in the scene also affects performance: The more textures, blending, and noise a material has, the longer it takes to calculate the results. The version of iray provided with 3ds Max is iray v2. This version supports the Do Not Apply Bumps To The Diffuse Shading togglethe round corner effect, many procedural maps; sky portals, glossy refractions, translucency, and IOR index of refraction ; and the ability to handle large output resolutions.
The iray 2. These can improve rendering quality, but in some cases they can slow down the renderer. These guidelines can help you decide whether to use Sky Portals:.
The iray renderer supports only certain material, map, and shader types. In particular, it does not support programmable shaders in the way the mental ray renderer does. If your scene contains an unsupported material or map, the iray renderer renders it as gray, and reports an error in the Render Message Window. In general, the iray renderer supports only material and map or shader features that relate to physically based light-ray tracing.
The iray renderer supports mainly the general-purpose mental ray materials:. It ignores settings on the Fast Glossy Interpolation rollout.
It ignores most of the settings on the Advanced Rendering Options rollout. It ignores shaders specified on the "mental ray Connection" rollout. Exception: Autodesk Metallic Paint is not supported. The iray renderer supports these maps and shaders:. On the Coordinates rollout for a Bitmap, the coordinate type must be set to Texture.
The Map Channel value must be in the range 1 to 4.Iray is integrated into Rhino, rendering directly within its viewports to give you continual, realistic feedback as you craft your model's form, materials, and lighting.

Select an object with the red material, mouse button 3 to open the object commands, and pick Select All Objects with this Material.
Converting JPEG textures into IRAY shaders...?
Now choose the blue plastic to apply it to the drill housing. You can review your changes and even show a customer or colleague this new material variation. But say you wanted to see this plastic in a darker shade of blue. You need only change the color of the Base Matte layer. Choose the color you would like and hit OK to apply the changes.
Save it to the folder corresponding to the palette folder.

The Iray implementation in Character Creator and iClone comes with a collection of easy-to-apply materials that do not require the user to have in-depth knowledge in CGI techniques, thanks to its material and light auto-conversion workflow and a vast material library. Character Creator CC can create realistic looking, animation-ready 3D human characters for use with iClone and other 3D tools. Interactive mode yields high-speed realistic rendering that can handle most naturalistic visuals including metallic surfaces and subsurface scattering.
Photo-real mode goes a step beyond with advanced effects like caustics, reflections, refractions and complex global illumination at the expense of time. Iray provides a full range of lighting techniques including High Dynamic Range Image-based Lighting, emissive materials, physically based Sun and Sky.
At the fundamental level, common directional, point, and spotlight systems can be easily converted from iClone light props. You can synchronize sky textures to IBL images, create your own IBL maps from 3D scenes, and then blend and animate them to achieve dynamic lighting effects.
NVIDIA MATERIAL DEFINITION LANGUAGE
Mesh Light for Iray is a highly versatile lighting system defined by emissive materials from scene objects. Emissive materials emit light across their surface area.
They contribute to bounce lighting in your scene and the associated properties such as color and intensity can be changed using iClone glow maps. Iray features an advanced sun and sky system based on the highly accurate atmospheric simulation. Compute blue skies and red sunsets while abiding to physical laws of nature or render any time of the day realistically and expeditiously.
The IES standard file format was created for the electronic transfer of photo-metric data over the web. It has been widely used by many lighting manufacturers and is one of the industry standards in photo-metric data distribution. Iray for iClone plugin translates cameras directly into Iray while retaining key attributes such as positioning, aspect ratio, depth of field DOF and FOV. Realistic camera effects can be achieved with a combination of Iray tone mapping, white balance, bloom, exposure value EVand render passes.
Iray Render Plug-in allows for the creation of state-of-the-art workflow with access to photo-realistic and physically based 3D rendering technology by simulating real-world physical behaviors of light and materials.Shaders and Materials

Mesh Lighting Emissive Materials Mesh Light for Iray is a highly versatile lighting system defined by emissive materials from scene objects. Sun and Sky Iray features an advanced sun and sky system based on the highly accurate atmospheric simulation.I am starting to play around more seriously with the Iray renderer in Daz Studio. The great thing about Iray, is that we can create realistic looking renders without having to muck around too much with lighting. Another really big advantage of Iray, is that we can get pretty good render results in a fairly short amount of time, if we have a good nVidia graphics card.
In this tutorial, I will describe how I started out with Daz Studio Iray, and how I created a simple realistic render from start to finish. This tutorial is intended for Iray beginners who are already familiar with the standard Daz Studio Interface.
I create the scene in the same way as I would in regular Daz Studio. However, one very important aspect of getting a scene to look right in Iray is in using the right materials. In this tutorial, I make a very simple scene with a female figure and a dragon tattoo on her back. She has interesting, long, wind-blown hair and is wearing a bikini. I make sure to use a highly detailed and realistic looking skin on my human figure.
In this example, I am using the Bambolina skin by Tempesta3d. This simple scene allows me to focus on learning the basic material and lighting aspects of Iray. After I finish creating my scene, I need to apply Iray shaders to all of my scene objects figures, clothing, props, environment. One simple way to do this, is to —.
This finishes the material setup of my simple scene. As I learn more of Iray and create more complex scenes, I will probably want to do more here to get the best render results.
However, that is for a later time and tutorial.
A very simple way to light my Iray scene in a realistic way, is to use an image based light IBL. To do this —. For example, rendering at Environment Intensity 1 and Environment Map 1 gets me the same result as rendering at Environment Intensity 0. Dome Scale Multipler and Dome Radius allows us to scale our environment map, and Dome Origin allows us to reposition our environment map.
I set Dome Scale Multiplier to 3 so that I can see more of the image in my scene.
Next, I want to position the sun in the image map at the right place so that it casts a nice rim or silhouette on my figure. To do this I need to better understand how my image maps onto the 3d-dome in my scene. A simple way to think about it is to divide our image into four segments. Essentially, the left of the image maps onto what we see, and then it goes clock-wise from there.
The sun in our image is in section C back of the dome. Therefore, to move it to the front of my image, I rotate the dome by degrees. This gives me a nice rim or silhouette effect on the left of my figure. Rotating degrees shifts the light-rim to the right of my figure.
However, it looks like there is also too much light in my scene, and there does not seem to be enough contrast between the rim set by the setting sun and the rest of the image.Forums New posts.

Thread starter brian foley Start date Aug 6, Tags ds iray shader factory. Has anyone seen a tutorial on this or even have done it yourself? In 3Delight ParticleFX works In iray it doesnt Pendraia Seasoned Contributing Artist. What are you trying to do with it? Very simple I might say I need to learn how to convert my jpegs into shaders for use in IRAY IRAY doesnt see the Particles from my emitters Using instancing in DS thru my Plugin.
So the short Question How do I do this? I am thinking I can still use the mip maps as the base texture then run the shaders off of that? I didn't know you could mip map Jpegs I thought that was just dds files.Narrow your search by specific forums. Iray Materials Posted By lvanvalk 2 Years Ago.

Senior Member. How do I access the Iray materials in CC3 to use as fabric in sweaters, sofas, or the wood for floors? In the video it looks like you only have to drag and drop but when I do, nothing happens. I also can't access the materials from iClone so I can't use the materials on any props, floors, or anything I need for my scene. Very frustrating and disapointing. Iray materials Distinguished Member.
You will not see the materials in CC. They only work when rendered in Iray. Can you show us how it works, a demo please. This video really helped me in CC3, is there any way I can use the material in iClone 7? Thank You Gerry Back To Top. Reading This Topic. Reply Quote. Space Rider. Space Rider Posted 2 Years Ago.

This was a big help. Thank you very much. The iClone update that supports Iray is not release yet due before the end of this year. So, today? The answer is, "No. I assume "Yes" since a material is a material, so it ought to work. Character Creator Thank you.
