I was about to add platforms (IN DAE) and export it to p3dv4 mdl so i can see the model as it will look at sim.
Then i had to change layers and No z-write options. i exported again and all textures and materials gone
It happens to me all the time. When you save the file in a different format (even FS2004 MDL to FSX MDL) the file no longer is linked to the location of the textures unless they are in the same folder or in the texture path in Options). I need to restart MCX to get the textures to display again.
