Strange shadows have appeared on the model preview images in 3D warehouse.
The each preview image of my models has gradually changed from the original one to the other with strange shadows and vision.
This phenomenon has already appeared to the model preview images of 67 models in my models.
The model preview images have still continued to change one by one.
It would seem that this problem may be due to some rendering pipeline in 2018 or imperfect upper compatibility of SketchUp 2018.
