Advice AI models for P3D

[ozflyer 2]

Hi All

I moved from FSX to P3D v4 and I only fly on online on VATSIM, so have traffic slider at 0 in FSX settings.

I had MTL and it worked brilliantly, never had an issue model matching.

Now in P3D v4, the fuselage is black, no landing gear etc.

Is there a utility to automatically convert MTL models to FSX version?.

If not, my option is to get a payware traffic program?.

I don't need traffic, just need the models to display online traffic.

Any recommendations or workaround for MTL appreciated.

Thanks
