Q: After creating OSGB scene cache for the vector layer in the scene in SuperMap iDesktop 8C, I found labels of the original label layer display as black blocks. Why did this happen?

A: It is mainly because that the osgb scene cache does not support two-dimensional symbols in the scene. If you want to use osgb scene cache, it is recommended that you use 3D objects and 3D symbols; otherwise create the vector scene cache for the data.
