Blender's image drawing and texture drawing

[BLENDER] Practical skills丨Unable to draw textures丨Wonderful situations arise when textures are drawn and you have no idea what to do? _哔哩哔哩_bilibili

Implemented blender's function of how to color images

Reflection on blender

Image drawing means drawing on a model with a uv map

So the model must have a uv map

Texture drawing is when your model has been expanded uv can be directly painted on the model

About exhibition uv

Model

First expand the uv of a module, select the object mode, the object enters the edit mode, and expand the uv

Then zoom and move on the uv panel, etc. The uv panel can select the surface point line to select

Adjust all uvs

In the object mode a select all, enter the edit mode, a select all the faces, you can see the uv of the non-stop model, and then put it on the same panel

It is best to check whether the model is facing the wrong direction first, and it is best to unfold the model one by one intelligently, or mark the stitching line to expand, otherwise there may be overlapping UVs, and the color will not be painted

Select image drawing panel

Create a new image, then select texture drawing on the right, and draw directly on the model

save, image

Then go to shading, create a new material

Then link the image to the image texture blender's material

texture painting

Draw directly on the image, you can see the effect in

Can't draw on texture

1. Selecting the wrong object

2. Did not expand uv

The picture is expanded

3. The case where the drawing model cannot be painted

3.1 Because the faces are reversed

Select an object, in edit mode, facing

Select the reverse side alt+n flip

4. There are multiple uv maps

A model itself comes with

If the displayed uv is different from the operated uv, it will not be drawn

5. The mapping relationship of the image in the shader is wrong

Unity succeeded

Successfully display the model and texture on Unity

Import model fbx can be multiple parts or combined into one model

Then import the texture into the texture folder

Create a new material folder

Create a new material drag-in object

Drag the texture into the material
