how to render pencil drawing in 3d max

The Quicksilver hardware renderer and the NVIDIA^® iray^® renderer requite you culling ways to render a scene.

Other tutorials that demonstrate rendering use either the default Scanline renderer or the mental ray renderer. The Quicksilver renderer creates quick hardware-supported renderings, and also offers non-photorealistic rendering styles. The iray renderer provides physically accurate rendering with little preliminary setup.

Skill level: Beginner to Intermediate

Time to complete: 45 minutes; perhaps longer if you lot cull to create an extended iray rendering

Training for This Tutorial

• If yous have non already downloaded the tutorial files (MAX scenes and other assets), download them now and unzip them into a project folder chosen \Autodesk 3ds Max 2015 tutorials. See Where to Find Tutorial Files.
• On the Quick Access toolbar, click (Project Folder) and prepare your current project to Autodesk 3ds Max 2015 Tutorials.

  

Employ the Quicksilver Renderer for Fast Results and Stylized Images

Important: To utilise the Quicksilver hardware renderer, your graphics hardware must support Shader Model iii.0 (SM3.0) or a later version. If yous aren't sure what graphics hardware you lot have, in 3ds Max choose Assistance Diagnose Video Hardware. This displays a dialog with details nigh your graphics configuration, including GPU Shader Model Support, which shows the Shader Model version number. If you can't run the Quicksilver hardware renderer on your system, skip ahead to the next department, "Use the iray Renderer for Concrete Accuracy."

Ready the scene:

• On the Quick Access toolbar, click (Open File), navigate to the \scenes\rendering\renderers folder, and open barcelona_chair.max.

  Note: If a dialog asks whether you want to use the scene'due south Gamma And LUT settings, accept the scene Gamma settings, and click OK. If a dialog asks whether to use the scene's units, take the scene units, and click OK.

  The scene shows a living room with windows and a chair in it. A painting is on the wall.

  

Use the Quicksilver renderer to return the scene:

1. On the main toolbar, click (Render Setup).
2. On the Render Setup dialog Common tab, scroll downwardly to the Assign Renderer rollout. Open the rollout if it isn't already open.
3. On the Assign Renderer rollout, click the (Choose Renderer) button to the correct of the Production label.

   

   The Production renderer is the one used to render finished output.

   3ds Max opens the Cull Renderer dialog.

4. On the Choose Renderer dialog, click to select Quicksilver Hardware Renderer from the list, and then click OK.

   

5. On the Render Setup dialog, click Render.

   3ds Max uses the Quicksilver renderer to render the scene.

   

   The Quicksilver renderer uses your system's CPU to prepare scene information for rendering. It uses the graphics card (Graphics Processing Unit, or GPU) to perform the actual rendering. The first fourth dimension you render a scene, the CPU needs to compile the shaders used in the rendering. This tin accept some time, merely it needs to happen simply once per shader: Subsequent renderings are faster than the showtime rendering. For instance, on one system this scene initially takes over 30 seconds to render, but subsequent renderings have only 5 seconds or less.

   The Quicksilver hardware renderer supports a express set of materials and maps or shaders. For details, see Quicksilver Hardware Renderer.

   To render scenes speedily, the Quicksilver renderer simplifies shadows and some other scene details. This will be apparent when you compare the Quicksilver rendering with an iray rendering of the aforementioned scene, afterwards in this lesson.

Try one of the Quicksilver renderer's not-photorealistic styles:

1. On the Return Setup dialog, go to the Renderer tab.
2. In the Visual Way & Appearance rollout Visual Mode grouping, click to open the Rendering Level drop-downwardly list, so click to choose Graphite from that list.

   

3. On the Return Setup dialog, click Render one time once again.

   3ds Max renders the scene again, this fourth dimension in the mode of a pencil sketch.

   

   You might want to experiment past rendering the chair using other not-photorealistic styles.

Use the iray Renderer for Physical Accuracy

The iray renderer generates images past tracing light paths. It is especially good at rendering reflections, including glossy reflections as in this scene, and self-illuminating objects. Like the Quicksilver renderer, information technology supports a limited fix of materials and maps or shaders. For details, see iray Renderer. As long as your scene uses physically based materials, such as Autodesk Materials, and photometric lighting, the iray renderer creates physically accurate results.

The iray renderer does not crave any item graphics card, and can run on the Central Processing Unit alone. Even so, a graphics card with a CUDA-enabled Graphics Processing Unit (GPU) improves the performance of the iray renderer without irresolute the result (CUDA stands for Compute Unified Device Architecture).

Tip: Depending on scene geometry, the iray renderer tin can use a lot of retentivity and take time to give a good result. Before you launch an iray rendering, it is a practiced thought to shut other programs, peculiarly graphic or sound applications, and to plan on taking a intermission away from your computer.

Prepare the scene:

• Continue from the previous section. If you had to skip the previous section, then on the Quick Access toolbar, click (Open up File), navigate to the \scenes\rendering\renderers folder, and open up barcelona_chair.max.

  Note: If a dialog asks whether you want to employ the scene's Gamma And LUT settings, take the scene Gamma settings, and click OK. If a dialog asks whether to use the scene's units, accept the scene units, and click OK.

Create an iray rendering:

1. If the Render Setup dialog is not already open, then on the main toolbar, click (Render Setup).
2. On the Common tab Assign Renderer rollout, click the (Choose Renderer) push to the right of the Production label.

   

   3ds Max opens the Choose Renderer dialog.

3. On the Choose Renderer dialog, click to select "NVIDIA iray" from the list, and and then click OK.

   

4. On the Return Setup dialog, go to the Renderer tab. On the iray rollout, cull Iterations (Number Of Passes).

   

   The main iray renderer controls simply set the duration of rendering: Yous can cull to set the fourth dimension in hours, minutes, and seconds; to specify the number of iterations; or to set an Unlimited rendering. The Unlimited option is good for overnight rendering.

   If you leave the value of Iterations gear up to its default of 500, rendering this scene takes about 5 ane/ii minutes, every bit tested on a dual-processor 64-scrap system running at ii.6GHz, with graphics-card acceleration. If your rendering is taking longer than you want it to, you tin abolish it then reduce the number of iterations.

5. On the Render Setup dialog, click Render.

   3ds Max uses the iray renderer to render the scene.

   The commencement iteration is dark and grainy.

   

   Each iteration adds detail and reduces the graininess. Later on several iterations, the scene begins to become clear.

   

   Here is the result later the full 500 passes:

   

   Compared to the Quicksilver rendering in Realistic style, the lighting and shadows are much subtler, and the curtains and their shadows prove fine details that were non apparent earlier. Lighting and reflections on the painting are subtler, too.

   In that location is still some graininess in the darker shadows: An Unlimited rendering would correct that.

   

   Overnight is a convenient style to run the Unlimited option, though for this model, it doesn't take as long equally that to eliminate the graininess in the shadows.

Save your work:

• Save the scene equally my_chair_rendered.max.

Summary

• The Quicksilver hardware renderer is adept for quick rendering assisted by the graphics card. It besides gives y'all a choice of non-photorealistic rendering styles that mimic artwork created by hand with traditional media.
• The iray renderer is good for physically authentic rendering that requires trivial setup aside from your choice of physically based materials and photometric lights.
