Where are the 3dmax normals and what exactly are the normals used for in 3DMAX?

One: What is a "normal". In 3DMAX software or other three-dimensional software, the faces of the model we build are divided into positive and negative sides, and making a straight line perpendicular to the surface in each of the smallest constituent surfaces of the model is called the normal of the surface.

Normals have a direction, and if we flip the normal, we flip the face on which the normal is located. Being able to understand the relationship between normals and surfaces can help us better model and understand the model.

Two: Flip the normal in 3dmax.

Select the object you want to flip the normals--- add a Normals in the Modifier List on the right--- select Flip Normals in the Normals modification parameters.

When we build the model, the object will become black after the appearance, and we need to see the object behind the object after the appearance, at this time, we need the object to be blanked by the face.

1: Blanking the backside before loading the normal.

Since we want to see the object behind after the translation, then we have to blank the back, select "Custom" in the menu bar - select "Preferences" - select "palatable" - tick "Back blanking when creating object", and then create an object Load the Normal modifier, you can see the object behind you.

2: Blanking the backside after loading the normal.

Select the object to which the Normal modifier has been added--- right-click and select Object Properties -- check "Backface Culling".

1.Open the scene and locate the model that has the Turn modifier.

2.In the Parameters panel, you can find the flipped normals.

Attribute. <>

Your current model,It's extruded with a thread.。。。 You have to collapse into a poly to select the faces you find reversed at the face level, flip the normals...

Convert the object to a polygon, then look for the Normal modifier in the modifier.

Find normal on top of the extrusion

Remember to give points

In 3DMax, a normal is a vector perpendicular to a face that can be used to help adjust the display orientation of the model.

The specific steps to use normals in 3dmax are as follows:

1. Open the 3D Max software, click the left mouse button on the right side of the window, click the [Standard Primitive] button in the panel, select [Cylinder] and drag to draw a plane, and modify the color to brown.

2. Next, left-click in the [Modify] panel on the right, select [Normal] and click once.

3. Then, left-click and select the parameters on the [Normal Commands] panel, you can see the default parameters, and the shape of the cylinder does not change when the parameters are not changed.

4. On the [Normal Commands] panel on the right, modify the parameters, select Flip Normal Parameters from Unified Normal Parameters, so that the cylinder changes.

5. In the perspective view, select the [Standard Body] panel with the mouse to create a box, and see the effect of the three-dimensional box through the normal command.

6. Finally, in the rendering perspective, click the [Render] button with the left mouse, and you can see the effect of the cylinder and the box after modifying the parameters through the normal command.

1. First of all, open the 3D Max software on your computer and draw a brown cylinder.

2. After selecting the graphic, in the "Modify" panel on the right side of the interface, select the "Normal" option and click on it.

3. Then use the left mouse button to select the parameters on the [Normal Command] panel to view the default parameters, when the parameters remain unchanged, the shape of the cylinder will not change, as shown in the following figure.

4. Then on the [Normal Command] panel on the right, uncheck "Unified Normal", and then check "Flip Normal" to make the cylinder change, as shown in the figure below.

5. After the above settings are finally completed, you can flip the normals in the 3DMAX software.

Displays which face is not displayed . The main purpose is to improve the computing speed of the computer. For example, if you are doing an indoor scene, then the exterior wall part does not need to be seen, then it is best to use the single-sided modeling method, but pay attention to the physical properties of the side that is not displayed on one side, but it is not displayed, if you turn on a light (turn on the shadow) outdoors, (the indoor side is the visible side), then the light will not directly pass through the invisible and shine in.

Hehe, I hope you understand, and I have been thinking about it for a long time to sum it up.

The premise must be under poly, first element, right-click will bring up flip normals

Click on it and you're good to go! Then you'll see the other side of the object!

It's very simple, ask the teacher.

Normals are vectors that define the direction in which a face or vertex is pointing. The direction of the normal indicates the front or outer surface of the face or vertex.

That is, in the direction of the normal, are the visible faces (visible in the rendering). Conversely, faces that are not visible (not visible in the rendering).

Face normals can be manually flipped or unified to resolve surface errors caused by modeling operations or importing meshes from other programs.

It depends on the specific situation. When you are at the polygon sub-level of a polygon, you can find the "Flip" command.

This command flips the selected polygon normals. When you use the turning command and you find that the resulting graph is black, it's time to check the "Flip Normal" command.

Even the Loft command in the compound object has an option to "Flip Normals", which are tools that Max has in store for us.

It's actually a vector perpendicular to the plane on which the point is located.

In 3ds Max, every 3D shape has two sides, and by default, the reverse side of the shape is not visible. 3ds Max creates a vertical line on the front of each face of the model, and the direction of the vertical lines determines the orientation of the front of the model, the front of the model is outward when they are outward, and the front of the model is inward when they are inward. These lines, which control the direction of the model's surface, are called normals.

When creating a shape, it is very likely that you will encounter inconsistencies in the normal direction of each face of the shape, which means that the front of the shape is facing outward and some inward, and you can use the Normal Alignment tool to unify their normal directions.

Also, when assigning a material to a shape, the effect of the material is only shown on the front of the shape, unless it is a double-sided material. If you want to control the direction in which the material is displayed, you can also do so by adjusting the orientation of the normals.

The function of the normal is to distinguish between positive and negative sides.

When the model is lit up, the vertex normals are required as parameters.

There are three types of normals available in the Normals modifier:

Unassigned: These normals are the modifier's export from the smoothing group and were originally assigned to the modified mesh vertices.

The software calculates the orientation of an unspecified normal based on the average orientation of all multiple deformations to which the unspecified normal belongs contained in the smoothing group to which the unspecified normal belongs.

By default, each vertex has the same number of normals as the number of unique smoothing groups used by the surrounding polygons. For example, by default, each side of a box uses a different smoothing group, so each vertex where the three sides intersect has three different normals.

Each normal is perpendicular to one of the three sides. A sphere, on the other hand, uses a single smoothing group, so each vertex of it has a normal that is perpendicular to the average orientation of the polygons that share it.

By default, unspecified normals are shown in blue.

Assigned: These normals are used by specific angles of a particular face, regardless of the smoothing group.

For example, you can create a box, apply Normals, select a set of normals for a specific vertex, and then click Unify.

At this point, the three faces are explicitly told to use the uniform normal, and they will ignore the smoothing group at that vertex.

However, the specified normals are not set to explicit values; They ignore smoothing groups, but are still based on the face normals of the faces that use them.

Assigned normals are displayed in cyan.

Explicit: These normals are set to a specific value.

For example, if you use the Move or Rotate command to change the default value of a normal, you must change it explicitly so that the value is not recalculated based on the face normal.

By default, explicit normals are green.

Note: Explicit normals are also considered to be assigned.
