Issue Description:

Hello,
In this particular work, materials that exist in the preview disappear in the final render. This doesn’t happen with all materials, just some of them. To continue working, I renamed the problematic materials in Sketchup and reapplied the materials in D5 Renders, save the file and then render. However, whenever I close the file, the problem comes back and I have to do the whole process again.
This also happens with other scenes.
What could be the cause? How can I solve it?

Thanks

Hello, when you rendered the image, D5 Render is still being synchronized with SU or not?
If possible, please send this sample scene file and the skp model to my email ziyin.zhu@d5techs.com for further troubleshooting.
