P3D v4 My taxi lines and skids are disappearing

I guess it is the same but I do not know how Blender works.
In that case merge the Blender made mdl's (there should be more than one) with the photo real ground mdl.
Great. Keep me informed. You could send me a PM instead of continuing this thread unless somebody else with more knowledge of Blender chimes in!!!
I do not think so. I guess it would be the same unless you make one mdl for each layer and then merge the mdl's.
I do not use FSDS to make ground poly. I use the ADE GP-editor.
