If the model looks perfect in the SketchUp but the textures are missing after uploading and only shows the color of the material, we need to modify the model.
Reason: Failed to read model data
Solution：reattach the material in SketchUp
- Double click to enter the model group, select the faces need to be edited(make sure to select in the bottom group);
2. Select the material and attach to the model, save and upload again.
Then we can get a perfect model in Coohom.
