The reason and solution about 3ds Max rendering is not enough real

The-reason-and-solution-about-3ds-Max-rendering-is-not-enough-real

Maybe you will find that the rendered pictures look fake and not real enough when making renderings. So what determines whether the rendering is real enough? There are certain methods in the process of model processing, material production, lighting arrangement and post-processing. The problems may appear in the following aspects.

If you want to make a realistic style effect, five of them are particularly important: composition, black and white balance, lighting, materials, and rendering settings.

  1. Composition

Ordinary cameras and physical cameras of some renderers can achieve good composition effects. Their use principles are the same as real photography principles, such as depth of field, focus, composition, etc., and they involve many knowledge points. If you want a good composition, then learn the principles of photography.

  1. Black and white balance

Black and white balance involves balancing the intensity, temperature, and contrast. You must also learn the light balance analysis method through the light! Different processing methods for day and night scenes, office and bedroom color temperature control, and so on. Step-by-step headlights are needed to create a layered sense of light. The most important thing in this session is to design the lighting atmosphere.

  1. Lighting

The combination of different lights in different scenes will produce different effects. Pay attention to the extension direction of the lights when you arrange them, so you need to grasp the direction of the lights from the details.

  1. Material

The material of the model is a very important step if all the other steps are fine. Different materials, different gloss and transparency, reflection intensity, softness and rigidity of the fabric and so on all need to be obtained by adjusting the material. For example, the production of floor textures, just like the production of daily wooden flooring, the first layer is first processed into the shape of the wooden floor, with highlights and reflections along the direction of the wood grain. The second layer is waxed. The entire wooden floor has a relatively high reflection and does not follow the texture. On the third floor, people walked through the dust floor that was not cleaned.

The more detailed the material of the model, the more realistic it will be.

  1. Rendering settings

The parameters are not important, what is important is what effect you want, but you must pay attention to the setting of the lighting. The lighting follows the real principles. Look at the lights, see the real feeling, see the light and shadow relationships, see the details of the objects, and see if the structure is reasonable.

In addition to these five principles, there is one more important place: the model.

Details determine success or failure, and the same applies to models. If the model in the scene is not fine enough, then the rendered thing will definitely look lacking in real texture. A good model, even in the case of a prime model, still feels true and natural. And the ratio of all models to the surrounding environment must be correct.

As the leading render farm in the CG industry, Fox Renderfarm recommends that if you want to have a good work, you must repeatedly debug the details of each link in modeling, materials, lighting, rendering, and post-production to achieve the best. status. For the control of light, shadow, and material details, it is even more necessary to observe objects in real life. Various factors can be combined to make a good work.

Big News! 3ds Max 2021 Is Now Available
Big News! 3ds Max 2021 Is Now Available
Hey guys! Let’s check out the new features in the lately released 3ds Max 2021.1, including texture baking improvements, Arnold as Default Renderer, expanded PBR workflow capabilities, viewport, fluid and modeling tool enhancements. The feature-rich update is targeted at modernizing and upgrading performance for artist workflows across design visualization and media and entertainment disciplines. Bake to Texture: - Output now supports multi-tile UV mapping (UDIM) - Animated map outputs are now supported as well as multiple animated frames - Various usability improvements. Model courtesy of TurboSquid and their artist, Luke_Ahearn. Fluids: - The Fluid loader is now exposed so that object types such as particle systems can work with the data - The Velocity channel now reports correct information when not using meters as your default scene scale. This fix will enable motion blur in your renderer - PRT now supports a signed and unsigned integer values (via .ini change). Interactive Extrusion and Inset: - Users can now utilize a Shift+Drag (left mouse button) with the Move transform tool to extrude polygon component selections when using an Editable Poly or an Edit Poly modifier - Shift+Drag with the Scale transform tool now performs a polygonal inset action on selected polygon component selections when using an Editable Poly or an Edit Poly modifier - Clone/Copy actions are now performed with Ctrl+Shift+Drag when using the Move transform tool on the polygon component on and Editable Poly or an Edit Poly modifier. Viewport improvements: - Depth of field now affects the environment map - Vignetting scale is now the same value as defined in the camera - Matte/Shadows material now work in the viewport - Each view can now have its own exposure, white-balance and vignette settings. Arnold renderer: - MAXtoA 4.0.4 - AOV token system - Animation support for Alembic - Increased shader spinner accuracy - Bake to Texture support for projection of normals from high to low resolution, normals spaces, and Mikkt. Enhancements and Changes Weighted Normals Modifier Now includes support for multi-threaded processing to enhance speed and performance when performing calculations as well as other stability improvements. Explicit Normals Preservation for Mesh Applying an Edit Mesh modifier no longer invalidates explicit normals, nor do the following actions: Attach, Detach to Object, Detach to Element, Clone to Object, Clone to Element, Detach as Clone to Element. PBR material Both PBR materials now support displacement. Shared Views Shared Views now supports Physical material. SketchUp model importation There is improved handling of internal edge visibility, improving the imported mesh quality, and SketchUp 2020 models are now supported. Slate Material Editor The Slate Material Editor now pans and zooms smoother and faster when using a 4k monitor. In addition, the Search field has been improved to perform global search through all materials and maps in the editor. For example, if you were searching for the Advanced Wood map and typed "wood," the old search would not find it but now it will. Render output size HDTV resolution of 1280 x 720 is the new default output size. UDIM display When you work with UDIM, you are now able to view all textures in the viewport when using the Bitmap Lookup OSL shader, instead of just viewing one as when using the Multi-Tile map. User Defined Defaults Allows you to set your own default values for ParamBlock2 supported spinner, radial, checkbox, or input field through MAXScript calls. Viewport Depth of field now affects the environment map, the vignetting scale is now the same value as defined in the camera, Matte/Shadows materials now work in the viewport, and each viewport can now have their own exposure, white-balance and vignette settings.

Next, we will share the production process of two other materials: Making wood material Pay attention to the following points when making wooden materials: • When you split the UV, try to place the squares as much as possible to ensure that the post-texture image will not be distorted. • It is also necessary to consider the utilization rate of UV space and try to give priority to the things you can see, which can improve the quality of the material. • The texture of the wooden structure is simple to produce, and it is necessary to find a lot of references that combine with the situation of the scene. For example, what does the wooden structure look like in an underground wet environment for a long time? Or the wood in this environment is more corroded? So to make such a feeling, a lot of references is very important. Substance Painter wood texture production • Import the baked Normal stickers and prepared materials into Substance Painter. Before creating something, create two fill layers, leaving only the Color option. One layer puts the AO diagram on the Color and adjusts to a positive overlay, which is used to improve the dark color. Another layer puts the Curvature map on Color and adjusts to Overlay, which is used to improve the bright color of the edge. After these operations are completed, the production of the texture begins. Pay attention to the production of wooden texture: Consider the actual situation of the scene. Take the scene we made (spy house) as an example. For a long time in a dark and humid environment, the corrosion will be relatively serious. Afterward, it should be noted that the edges of the wood will not be particularly bright. The bright edges of the wear marks will also be darker, and then the scratches and the wear of the places where they are often used. A little brightness is needed here. Finally, there is dust accumulation and stains in places that are not often encountered. After these things are done, you can basically get a good real texture. The material for making paper and book When making a single-page paper with no thickness, please pay attention to the following points: 1. When you split the UV, try to place the square as far as possible to ensure that the textures in the later period will not be distorted. 2. The texture of the paper is simple to produce, without Hight Polygon, just baking Low Polygon Normal. How to make paper in Substance Painter: Import the baked Normal map and prepared materials into Substance Painter. Create a layer (unfilled layer), select Color for the material and put the material in Base Color, and select None for UV Wrap. In F1 3D/2D mode, place the picture material in the corresponding position. Just pay attention to the book texture production: from the beginning, it is necessary to distinguish between the shell and the content. If it is made into one, it will not be easy to separate when making the texture. Marmoset Toolbag 3 rendering Finally imported into Marmoset Toolbag 3 for rendering, the first is to layout the light source, choose to add an HDR suitable for the scene, adjust the Child Light to the appropriate position to make the model produce a 45-degree shadow. Because the scene is larger, more lights are added, but when rendering, pay attention to adjusting the size and illumination range of those fill lights to prevent the mutual influence of light. I hope our learning and sharing can help you, thank you.

Material production After baking all normals, AO, and curvature, import Substance Painter to make materials. It is worth noting that the normals baked in Marmoset Toolbag 3 and Maya use OpenGL mode in Substance Painter, and the normals baked in 3ds Max use DirectX mode. The first step after successfully importing the model must be to check whether the normal direction is correct. After successful import, the remaining textures are baked in the texture set-baking model texture. The following uses the sofa leather material to share the basic process of the material: the production of sofa leather material. Inherent color of the leather Choose a suitable material map and paste it in the color channel, adjust other parameters appropriately to make the effect more natural Bump height Create a new fill layer to keep the height channel, paste the height map corresponding to the background color layer, and add Level to adjust the height. At the same time, add anchor points to ensure that the color changes with the height. AO layer The AO diagram of the model pasted in the AO channel is that the dark parts of the edges are deepened, and the bumps are more three-dimensional. Roughness Adjust the roughness of the sofa surface. Frequent contact with objects will wear more, such as the edge of the cushion, the inner and upper sides of the armrest, the bottom of the sofa, the top of the backrest, etc. Grunge textures can be added to make the effect more natural. The edge fades Create a fill layer and add a generator to produce a faded edge wear effect. Adding only one generator effect will be very stiff. Add a few more layers to interrupt the continuous effect to make the wear more natural, and finally, add hand-painted details. Details added Use the Grunge map to add scratches, stains, and other details to the surface. Dust There are two kinds of dust: dust accumulated in corners and trace dust on the surface. Create a fill layer to leave the color, roughness, and height, and then use the generator to calculate the dust position adjustment parameters to make the effect natural, and you can appropriately add hand-painted details. Gap treatment Manually add black to deal with gaps and other details.
