Make a grenade with 3DMAX

3DMAX Modeling is not friendly to novices , Zero foundation Xiaobai learning 3D Modeling requires at least 8 About months . Need to systematically study the foundation of Art 、3D Modeling related software foundation 、 Modeling and manufacturing process 、 Mapping and project practice training . Just put the above 5 Xiang Xuexue , Solid learning , For future work and employment, it will be small case 了 . Through the actual combat of this grenade model, I become more skilled 3DMAX The operation of , Make a summary through the project .

One 、 Create a projectile model

1、 View -〉 Viewport configuration -〉 Layout -〉 Choose left and right

2、 The upper left corner of the left view , Select left 、 Plane + highlights + Side face （ It's best to change the view direction on the left , Do not rotate at will ）

3、 The upper left corner of the right view , Choose perspective 、 Plane + highlights + Side face （ You can use the upper right turntable to rotate at will ）

4、 Press +, Hidden grid , Maximize the view

5、 establish -> Basic geometry -> The ball , Rename it to grenade

6、 Set in the modifier panel ： radius ：48, piecewise ：16（ The default value is 32, Not conducive to operation ）

7、 Right click the sphere -〉 Convert to -〉 Convert to editable poly

8、 Switch the left view to the top view , In the rollout （ Editable poly ） Select polygon , Select the upper and lower faces of the sphere , Press Delete Key to delete

9、 The border ->Ctrl+A Select all sphere objects , The actual two boundaries in the object are shown in red

10、 Edit boundary （ Select the boundary in editable poly ） -> Seal , Add a definite face to the object

11、 Press the shortcut key 6, Deselect the sphere object layer

12、 Click... In the toolbar “ Select and scale evenly ”, Along the Z Pull the sphere object upwards

13、 Click... In the toolbar “ Select and move ”-〉 Press down 4, Enter polygon level -〉 Select the top face

14、 edit poly -〉 Insert -〉 Set up Inset=8, single click √, Complete the insert operation

15、 edit poly -〉 Chamfering -〉 Set up Hight=14,Outline=-7, single click √, Finish chamfer

16、 Press down 1, Enter the vertex level -〉 Press down T, Switch to the top view -〉 choice -〉 choose “ Ignore Backfacing ”

17、 Select the two points on the top left of the sphere -〉 Edit vertices -〉 Connect , Connect the selected points

18、 Press down 4, Enter polygon level -〉 Select the top middle face -〉 Chamfering -〉 Set up Hight=14,Outline=-1, single click √, Finish chamfer

19、 Select the two faces on the left side of the top -〉 edit poly -〉 Squeeze out -〉 Hight=10 , single click √

Two 、 Create a fuze model

1、 Press down 2, Enter the edge level -〉 Select an edge in the middle of the left projection -〉 Press Ctrl+Backspace, Delete the selected edge and the extra points on the edge , Become a plane

（ The deletion effect is better from the perspective , Notice that the left and right sides are different ）

2、 Press down 1, Enter the vertex level -〉 Press L, Switch to the left view -〉 Select the top two points on the left -〉 Use “ Select and move ” Tools , Move the selected point down and left

3、 Select the four points on the left -〉 Edit vertices -〉 Connect , Connect the four selected points

4、 Press down 4, Enter polygon level -〉 Select the face below the protrusion of the object -〉 Squeeze out -〉 Set up Hight=10, single click √, Finish extruding

5、 Press down 1, Enter the vertex level -〉 Press L, Switch to the left view -〉 Select the point of the protruding part -〉 Use “ Select and move ” Tools , Move the selected point at a certain distance and angle from the main part

（ Change the angle of the face by moving two points on one edge of the face , Move the four points on the face to make the face stretch , The adjusted surface is used as the extrusion datum , It's best to choose a point after changing the perspective on the perspective , Move from the left view ）

6、 Repeat the above two steps , Squeeze it out twice , The handle of the grenade is finished

3、 ... and 、 Create insurance pin model

1、 Press down L, Switch to the left view -〉 establish -〉 Standard primitives -〉 ring

2 Drag and drop the mouse to create a circle , name Torus001,Radius 1=20,Radius 2=1.2, Segments=10, Sides=6

3、 Drag and drop the mouse to create a circle , name Torus002,Radius 1=2.5,Radius 2=0.8, Segments=10, Sides=6

4、 establish -〉 Standard primitives -〉 Cylinder

5、 Drag the mouse to create a cylinder （ Pull out the garden , Release the mouse and then press and pull ）, Radius =1.2,Height=0.8, Height Segments=1, Sides=6

6、 Use “ Select and move ” and “ Select and rotate ” Tools , Move two rings and cylinders , Combined into the shape of the pull ring of the grenade （ First, rotate and translate in all directions on the perspective on the right , Then select the left view on the left , Put the parts in place , Then change to the front view , Put the parts in place .）

Four 、UV Expand add material

1、 Press M（ Or select the material editor from the icon in the upper right corner ）, Select a shader on the material editor panel

2、Blinn The basic parameters -〉“ Diffuse reflection ” The map selection button on the right -〉 In the pop-up “ texture of material / Map browser ” Choose from “ Bitmap ”, single click “OK”

3、 In the pop-up “ Select bitmap image file ” Select... In the dialog box grenade.bmp, single click “ open ”, Determine the selection of the map file

4、 Click... In the material editor “ Assign materials to selected objects ” Button （ The... Below the shader 3 Button ）, Hold the shader and drag it until the object is released , At this time, the map is not displayed on the object. Click... In the material editor “ Display the standard map in the viewport ” Button （ The... Below the shader 9 Button ）, View the addition of model mapping in the perspective

5、 Select the grenade object -〉 modify -〉“ Modifier list ” The drop button on the right -〉 choice “UVW an ” Map modifier -〉 Click on “ edit …”-〉 Show “ edit UVW” window -〉 Select the map display mode in the upper right corner as “Map#0(grenade.bmp)”, That is, map expansion and model mesh routing are displayed in this panel

6、 Click on “ edit UVW” Below the window “ Choice mode ” On the far right “ Face sub object mode ”, Modify the mapping information of the model in the scene in face mode

Click on 3D The face in the figure , Display the corresponding area in the bitmap , Move each vertex position , send 2D Graphics and 3D Model matching

5、 ... and 、 summary

Mapping software is recommended Substance Painter, The design of the coating combines it with the updated seamless material sample project . Polygon modeling is suitable for building models with edges and corners , For example, this grenade model , It is also suitable for building models with smooth surface changes . Polygon modeling is a complete modeling process , It can't be accomplished with oneortwo commands . This blog uses the most commands in polygon modeling .
