Blender graphic tutorial: teach you how to make a Mario gold coin with the next generation modeling process

This article is part of the Mario Odyssey tutorial in "[Hands to Take You Godot Game Development Second Bullet] Facing G" .

Renderings

Low mode

Create a new one 柱体, enter it 编辑模式, and scale the cylinder to the thickness of the coin

In the 面层级front and rear two faces selection, then press Ithe key, inserted in the two front and rear faces face

Then Alt + Eselect沿法向挤出面

Retreat 物体模式. Renamed it to "coin_low", so that the gold coin's low model is done.

2. High mode

Generally, high models are produced by engraving, and we stole a little bit here.

Shift + DCopy a "coin_low", in order to avoid misoperation, we Hhide the original "coin_low", and then use the copied "coin_low" to make a coin high model.

Go back 物体模式, create a new patch, and add more subdivisions to it (the number of subdivision faces cannot be too low, otherwise it will affect the accuracy of the gold coin relief).
Note: It will be 细分类型set to 简单型and will be 细分修改器applied.

Then add to the patch置换修改器

Apply the patch 置换修改器, then copy a patch, flip it over, and put it on the back of the coin

Activate the BoolToolplugin

Select two faces and coins, then press to Ctrl + Shift + +pass three objects BoolTooland integrate one object

Rename this object to "coin_high", and the high model of the gold coin is completed.

3. Baking normal

Blender can bake normal maps, but the process is more cumbersome. In actual development, you can consider using other tools to complete this step. Personally recommend Substance Painter.

Note: Before baking the normal maps, you need to spread the UV for the low mold. Since the low mold used in this example is the 柱体UV that has been brought by Blender , we will omit the step of UV.

a. Add material for low mode

Press Alt + Hto display the low poly first , then add a material to it

b. Set the window layout

c. UV view

Create a new 512x512 Texture and name it "coin_normal"

Created

d. Shader view

Select the low mode and follow the instructions below to create the node

Image texture node

Set the texture to the "coin_normal" we just created

Normal map node

Connection node

e. Set baking parameters

First select the high mold, then press Shiftto select the low mold, and finally press the "bake" button

After baking, switch to to 材质预览着色模式see the effect of normal map.

summary

After using the normal map for the low mode, the visual effect is similar to that of the high mode (especially at medium and long distances), but its number of faces is only 0.3K, while the high mode has as much as 24K.
