Three. JS introductory learning notes 07: external model import -c4d to JSON file for web pages -fbx import
2022-07-07 15:48:00 【Jiang Duoduo_ Mostly Harmless 】
Used in the last article obj Import , Turn into json I found that some materials cannot be loaded , I don't know why .
such as blender Import obj When modeling , as long as obj and mtl Material files are in the same folder , Normal condition , Import obj At the same time, you can directly import mtl.
stay blender You can see the complete material obj Model , But with three.js Plug in conversion json When placed on the web , The material is missing .
This problem has not been solved yet .
So I switched to c4d turn fbx,fbx Import blender, use blender Of three.js Plug in conversion json The way , Put it on the web , In this way, the material can be better preserved .
fbx Import Blender Turn into json There are several problems that need attention and unresolved problems to be recorded :
I don't know whether the following is true , I didn't find the cause of the problem , It's just that the effect seems better
1.C4D export fbx when , You need to be able to group and Export , Each object has a material , Don't add or delete all levels of connected objects , Avoid having many materials on an object
2.C4D When adding or deleting connection objects , Adjacent and close ones are merged , A bad merger may break the page
3.C4D Reset coordinates in ,blender Middle alignment 3d The cursor , The last one had
4. The material needs to be painted on both sides
To be solved :
1. Some groups are separated , Also pay attention to the material , Still can't load the desired material effect , Unknown cause
2. Some materials are exported as fbx and json It's big , For unknown reasons
3. Axial overturn problem , What are the rules , Why does it flip , Unknown cause
4.Blender export three.js When , Shortcut key required a once , Select all and then select objects , Then export without error , Why is this
5. Load multiple json What are the simple methods for objects ?
Icon
C4D Add or delete all connection objects in , Multiple materials cannot
Upper figure blender It looks like this
The effect of not adding two sides is not good
There are individual objects in the Group , Each object has its own material , You can export a whole set
C4D Adjacent connection objects + Delete
When the whole group cannot reset the axis , It can only affect the axis , Change the origin position of the axis to 0,0,0 Just fine .
There are still many problems with the whole export , I don't know why
