Having this issue with P3Dv4.5.13.32067 (the latest as of this date). The ULD's are detailed, but darkly textured. Also, some of the textures on the PMDG 747 QOSIII are the same way. This leads me to believe it might be a P3D issue, but wanted to ask here as well as there if anyone has had the problem or, possibly, a fix they can direct me to. This does not happen in FSX:Steam, just P3D...
Thanks and keep up the great work..!
