Thank you for advice, but I do not use so preview directx 10. I use directx 9 with the Katana X
to avoid texture with no color (white).
However, I found a solution in the meantime best so as not to see in 3d panel,
theres a plate, bright and shine, like aluminium style around cadran.
When I fly, during the day, i closed all lights; strobe, Land, taxi, position, etc. and the plate
like aluminium style disapear.
It is not a perfect solution but it is best like nothing, pending better.
Hoping that this will help you.
