Hi, I tried this database and runway is white.
Not using *.flt file.
This forum is about the CDB specification. As you are using Vega Prime, please engage with the Presagis support for questions. The runway on this CDB is rendered with an overlay polygon with texture on top of the imagery and terrain elevation. This is called a Tiled2D in CDB. Clearly it is being loaded and rendered by VegaPrime on this screen capture. Please look at other regions of the runway to ensure you see markings. If not, support can help you. If you prefer to have the imagery and not see this overlay, you can deactivate it in your CDB configuration node in LynxPrime (remove the Tiled 2D datasets).
