After .obj files had converted to cesium 3d tiles, buildings created transparently. When I looked behind building, I saw another building. I dont want it. I want that these buildings are opaque. Is there any way for this?
Thanks!

Hi @talha,
It's possible that the OBJ textures have a transparency band in them. You can check by opening the OBJ file in the FME Data Inspector, then clicking on a surface. In the Feature Information window, expand the Appearance Reference to see the texture image properties. If there is a Band 3 (Alpha) in the properties, then your textures have a transparency band.
You can use the SharedItemRetriever and SharedItemAdder to update the textures in the library to remove the transparency, without needing to update the actual features, using the following method:
I have attached a workspace containing this process for you.

I wonder and demand help from you so as to a lot of improve this workflow. Only last step left for me. After I had created these buildings with FME, I saw that they were created dark color. When I used obj23dtiles package, they were created with bright color. I found that there was a statement which is Occlusion in article of obj23dtiles. I want to share this with you:
When I created these buildings with obj23dtiles, I got the result such as following:
When I created these buildings with FME, I got the result such as following:
